CRAZY PT Cruiser (Stall, No-Start, No Comm)
Вставка
- Опубліковано 4 жов 2024
- This 2005 Chrysler PT Cruiser Turbo left the customer stranded and got towed to a local shop.
The shop found some wiring damage, replaced a crank sensor, and the car ran ok...until the customer came to pick it up. He didn't make it out of the parking lot before stalling out xD
Let's diagnose this weird start-stall issue and give the shop an estimate for repairs.

I've seen this issue before and it took me some time to trace it down. One thing I learned is that the Cruiser will set communication codes if scanned while not running. To the point I found that power was intermittent to the computer. This would cause the car to run ruff, buck, and yes stall out. The dash lights would send confusing signals and when scanned, the codes were inconsistent never showing the same ones. Took a step back and went to the basics of checking powers and grounds to the computer. In the end it turned out to be a poor connection at the ASD fuse. As it turns out most of the power that runs this little vehicle goes through this fuse. It didn't blow but did show signs of excessive heat. Replaced the fuse and I was cruising in my automobile once again.
Probably something that was overlooked in diagnosis was not just the signals (data packs, waveforms to and from sensors), but 'ripple' on the supply feed in reference to ground, and when there is strange behaviour, check what that shows with another trace, or scope..
A fuse can show signs of over-temp when the fuse connections get oxidized to the point of increasing contact resistance. Which intern, increased heat which increases resistance and so on until the plastic housing starts to melt. If you catch this in time and clean the fuse mating contacts with Deoxit D100, and clean the new fuse contacts, with emery cloth and then Deoxit D100, insert the fuse, then remove and reinsert to wipe the contacts, you can drop the contact resistance down to the point where you can get some extended life out of it.
However, if we step back and want to study the problem in more detail, a relevant test before swapping the fuse or cleaning the contacts would be to monitor the voltage across the fuse and fuse contacts while under load to understand the magnitude of the voltage drop.
No, just the fuse. About a year before this problem shown up I had a fuel pump failure. It may have drawn close to the fuse limit.

Sounds like you're in a clear flood mode, test the throttle position sensor.
If you're only having long cranks on first start up check the fuel pressure. Fuel pressure needs to hold for at least a half hour.
My buddy has a PT, he says it stands for Persistent Trouble. Good diagnosis Ivan. Cheers
Love your content been watching you since Staten island days inspired me to open a mobile mechanic business a few years ago bless you and keep killing it
That's awesome! Keep up the great work 👌👍
I am a do it myself oil change expert. Anything else I leave it to experts, but I enjoy watching this stuff. Weird
I feel like watching channels like this one only serves to convince me how few experts there are.
Should of had the guy that designed that GOD DAMN dinger to do the PCM instead, it would still be running today. Probably the most reliable thing in the car.
Bought an 09 PT cheap from a friend. Been restoring it with junk yard parts. ALL, and I mean ALL the PT's in the yard are automatics, hence why they are in the yard. Mine is a manual, like this one, but without the turbo. Owning a PT is like owning a Harley, if you cannot do your own maint and repairs, which is pretty much constant, they are not cost effective to own.
Strange that a pt cruiser needs a immobilizer 😆
Its engineerd in, no parts required😂
😂🤣
Lmao
High demands .
I agree. You would think they would have put in a neon sign that said "please steal me." instead.
I've done a few of them PT's that had issues like this, and most of the time, it was something wrong in the ASD circuit. Burned but not blown fuse on one. Bad connection to or bad ASD relay on a couple of others. Something in that circuit was drawing more power than the circuit was rated for. And my sister had a 06 with a bad PCM. But it got junked shortly after sending it to the dealer for a 2nd opinion.

Confusing problem(s). Great chain of thought and corresponding diagnostic! Deserved to be repaired (unless the car is not worth the cost, although it looks OK).
Old Chrysler tech here. On some of the older jeeps 98 or so if the five volt reference to the map/tps and a few other sensors got shorted to ground it would cause the pcm to not communicate and it would result in a no start no communication. Unplug each sensor that shares that same 5 volt circuit untill comms come back. I think other Chryslers used the same controller and might be prone to that issue. I have an 03 PT/GT with a five speed. Drive it daily. Still runs.
Another great diag! Have not seen anyone work on a PT Cruiser in a long time! Thanks Ivan.
What's the customer complaint? He owns a PT Cruiser.
😂🤣
“Pretty cool car” - said nobody else ever with a PT Cruiser 😂
At least the owner did the right thing and junked it.
Putting it out of it's misery was the right call.
wrong!! i have a GT turbo everyone who sees it loves it
@@ferrumignisif it was properly maintained it would still be around
Smart customer!
Dude you are an awesome diagnostician, working on a PT Cruiser is beneath you. You should politely explain to your customer that you would be happy to help them with their car as soon as they purchase a real one.
At least it's a manual! And turbo! 😄
Winner, winner chicken dinner.
@@satamanschmidt3428 you'll like the next video Denis... A 2000 Pontiac Bonneville 3800 with no speedometer 😉
I had a theory that the 5v ref to the cam sensor could've been dropping out. Don't know if that could cause the behavior, but it would be consistent with a faulty ECM
Oil in the cam sensor.
Parked with engine facing downhill.
Replaced cam sensor.
Engine sounds ok.
In neutral, runs up to just under 4000 rpm.
Then bogs, and returns to 4K, and just buzzes around there.
Drives fine, but every warning light in the menu is on.
I want to say the is a TSB about this. I had this issue on several PT. Replaced the ecm and reprogrammed.
Thanks Ivan . I was expecting a bonus footage . But I don’t understand why the customer want to junk that cruiser? It is one of the kind because is a stick shift .😢 because the budget💰 or the car had more problem ?
More dollars than sense
Because PT stands for piece of trash. lol
If it's your daily driver, it's trash. I'd love it as a toy. I'm tempted to try to find it.... and send it back to Ivan! 8)
I don't know, while it certainly could be the PCM I would want to examine the repairs before blaming the computer. Junking the car seems kinda harsh, it looked pretty clean. On the other hand, it is a PT. But if it is the PCM then was the wiring issues not really the problem? Just doesn't seem quite satisfying. Thank you for posting the video still interesting to see.
The car looked to be in decent shape otherwise, with low miles. I'd love to have a turbo 5 speed PT, just to trigger the haters. I would have bought that car for scrap value, put a used PCM in it and had a blast on the cheap. Too bad it was junked.
Yea me too I am not much on PT cruisers but one with a 5-speed hell yeah the thing looks to be in pretty decent shape is it Rusty?
Thanks Ivan for another great video.
Verry talented, THE REASON YOU DON'T HAVE MILLIONS OF SUSBCRIBERS IS BECAUSE AT TIMES IS DIFUCILT TO KEEP UP WITH YOUR KNOWLEDGE
Ivan, sorry it ended this way. Would have liked to see this car back on the road again. I suppose the customer just got tired of dealing with it. Hope his next car is performing much better. Thanks for Sharing!
On the older chrysler transmission if to lost power it would set a solanoid coad for the first solanoid in the tcms check function and you would start chasing a solanoid problem to you understand that chrysler had a order in the self test program . Lose of power code for the first checked item in the self test programming
Hey Ivan😊🙋♂️, loved this video buddy. The ending was sad when you revealed the owner junked this PT Cruiser. Being I am a fan of the HHR's, I have a soft spot for the PT Cruisers as well. The one in your video is especially becoming more rare. Just like you said, 2.4L Turbo with a stick. And what makes that particular Cruiser even more rare, is the factory stereo. It has a CD Player and a tape deck. How cool is that lol. I hope it didn't get crushed though, hopefully somebody will save it. The Cruiser you worked on in this video would give my automatic HHR SS a run for it's money. Would be a heck of a good race. He would probably get me off the line but I would catch him at top end. Keep the videos coming, I enjoy watching during my morning coffee. Cheers buddy!
You gave your best try. Obviously the PCM would not communicate with other modules, something is shutting down inside.
My mom had a PT Cruiser. Man, that thing was a piece.
BUZZER never dies.
The good ol' wiggle check.
Personally I would have disconnected everything on the network one at a time to see if that affected the network because something was interfering with the network
2005 car not much modules talking on the databus , very unlikely that another device would cause this
Ivan is a damn good diag technician
Ivan, you should really take it to the next level and bench test PCM and other modules.
I could write it in python to simulate comms after i capture the messaging streams.
In Australia, there are several PT Cruisers travelling about, but wonder what Chrysler and its distributors did with warranty, and coming up with easily identifiable faults, for keeping them going. When they were introduced, the body shape represented a 'retrograde step' in design, harking back to the days of the 'Airflow' and introduction of hydraulic brakes.. (The 1930's and 1940's). In the 1960's, the fashionable design concept (in Valiants) was to keep a lower centre of gravity.. As for the electrical issues, and some experience repairing electronics, I would look inside the engine computer and check down to component level, but the customer has called it junk, and decided to 'cut his losses' in time and money spent on the vehicle...
Great work Ivan.
Crazy first PT of a 3 PT series indeed.
I'm sure it bothers Ivan that he will never know for certain what is wrong. It might be a no parts available problem and junkyard parts wouldn't be reliable.
The last time I had a PT do this to me the tb was loosing teeth. It would intermittently stall. Sometimes crank no start. Sometimes run perfect
Previous shop replaced cam and crank sensors. So I start scoping. And just when I was about to get both captures for cam/crank I get a crank no start. Constant. Pulled timing cover and and cams were no longer turning. Crazy that it would run, stall not run. Just depended on where along the belt the gears were catching.
That's insane lol!
Cool study, cant wait to see fix!!!
My wifes PT Cruiser is a 2005 AT Trans no spark no injector function getting healthy 12 volts to coil pack and hot side to injectors from ASD relay when
cranking . NO signals to coil or injectors (ground side switching from computer). Crank and cam with magnet sensors are new are getting 5 volt reference and ground at connectors to both sensors . Both sensors are providing voltage switching to computer measured at C-2 connector (orange)
Gray Black Wire (Crank) Tan Yellow wire (Cam) Tried junk yard computer replacement no luck have not tried new one.
Any codes?
@@PineHollowAutoDiagnostics Air temp sensor unhooked Code
Rebuilt computers are cheap for that car. I put one in my sister in laws 2005 PT Cruiser several years ago and its still holding up. Similar symptoms. My first guess was fuel pump but it was also shifting weird (automatic trans) and had a code I think was p700 or something like that along with a few others..
So let me tell you about the late to the party car that I had to diagnose one day... this car resembles something that made me misdiagnose a PCM. 🤓
Please continue Master Keith 😎
@@PineHollowAutoDiagnostics Now I'm really intrested.. Keith, help us out man!
@@PineHollowAutoDiagnostics Вот это поворот, да, Иван!?
Tipm ig feed . Pmc seems to always set a crank position sensor coad if it loses a power source. And It seems like when the crank sensor fails there's never a code for it . I think it has something to do with cranking voltage doesn't let the pcm see that the crank sensor is dead .
Oil light never goes out, unless I blow the horn.
Thanks, Daimler Chrysler.
Love your channel, I just started my own channel. You are a wizard with the scope, I am just learning with the scope I have the Snap On Zeus. When you are using the scope if you could go into teaching mode would be greatly appreciated. Have a blessed day.
My first guess is to check the connectors on the PCM.. Lets see what happens though
Don't think I am not noticing that you are starting to match apparel to the company logo 👁.... well done sir 👏
Hi Keith, Dennis here, how''s things in North Carolina? It's been hot as hell here in Phoenix but that's not much in the way of news.
Standard and a turbo!! Can’t believe they junked it.
I dunno, Ivan.....are you sure you don't want to buy it as a cheap toy? I realize you're probably not a huge fan of the PT, but with a turbo and 5 speed, might be fun to play around with....
Now I will sat this watching the video and you have just checked fuel pressure. I have had ignition switches go bad on older vehicles and cause this problem but it wouldn't be causing this issue on a newer car like this. First I would think immobilizer the pcm. Entirely possible to be pcm but the odds of the pcm going bad right after wiring damage from mice are low but and there's a big but here, if the wrong wires touched while the wires were damaged could it have caused the pcm to start failing. I would say it shouldn't cause the pcm to fail but could it have the answer would be yes. And with what I see I think it may have. Now for my favorite part, to see if it is in fact the pcm. Back to the video.
I don't blame the customer for junking it, my dad bought one back in the day and it was a nightmare for the entire life of the vehicle with the ONLY good quality being that it was good on fuel. It was in the garage being repaired more than it was actually on the road with one electrical gremlin after another. The final gremlin was that if you plugged in the rear O2 sensor it would blow the fuse for the transmission and refuse to start so it drove for the last few months with no downstream O2 till it was finally wrecked and put out of its misery. Lol
That's very strange that plugging in the o2 sensor blew a fuse unless the sensor was internally shorted. Either way it's stupid to design something in a way that a non critical part failing makes the whole thing unusable, but that isn't exclusive to Chrysler products. Years ago my Honda kept blowing the alternator fuse. When I finally figured out that the problem was a shorted EVAP solenoid, I was pissed that Honda put some nonessential emissions device on the same circuit as the alternator. Crap like that belongs on its own circuit or with something nonessential like the radio so it won't leave you stranded if it fails!
@@averyalexander2303 Yeah even a brand new sensor did the same thing and it didn't matter if it was O.E. or any other brand either. I traced the wires and there were no issues to be found so I attempted to check the wires inside the fuse box for any issues and every single wire inside was the exact same color making it a nest that looked like red spaghetti that took days to check but I may have missed a wire or something. Either way it made no sense to me or anyone else that looked at it so we just left the sensor unplugged.
my battery, a delco, was at fault. had dash lights come on followed by stalling as well as a very long seat belt alarm. even blew a 10amp fuse, which allowed the vehicle to crank but not stay running . tried to charge the battery on a trickle charger but after awhile i got an F01 error code and never finished on a regular charger. battery had plenty of spark but no reliability for starting the vehicle
You need to repair the MOBILIZER! 😆
That Cracked Me Up Ivan 😅 Be Nice If The Guy Would Stop Mowing And Blowing Dust Here So I Could Hear The Fuel Pump
Friggin` Landscrapers grrrrr
Who In The Heck Is Cutting Grass Anymore ? I Have Not Cut Mine Since The 20th Of June 😄
Probably the Pcm Demise Was Caused By The Rodent Shorting Some Wires
The Owner Should Have Put A Used Pcm In It And Sell It To Recoup Some $$$ Especially Now With This Economy smh
Great video/ if I only understood all the process- But it’s just like life/ keep up the videos/
Hello
You just said cool car
Well well well here in 🇬🇧 it’s a my biggest pet hate
Anyway good job and very knowledgeable approach to diagnostic and a perfect strategy
Take care
Great candidate for speeduino
Customer says diagnose the problem then junks it. Wow, that was sad! But don't really like PT cruiser lol. Too much of junk stuff. But cool video of the diagnosis with bad pcm. Very cool with the scope!
‘Which is not unheard for Chryslers” …….as I choked on my drink. Thanks for the laugh!
This video confuses me. No mention of inspecting the shop's repair, or looking at the area for damaged wires that were missed. Is the scoped CKP/CMP inputs or outputs of the PCM? I don't understand how the signals disappearing is the fault of the PCM. Bad/confusing inputs can cause all kinds of odd computer issues.
Agreed . Also the fuse . Just jump it real quick.
Inputs, powers, and grounds were all good at the PCM 👍
Ah dang. That's like the one desirable model 😥 the turbo can really be turned up & the 5 speed can handle it. Dang....
Brilliant as usual Ivan, I just have one query, what bus are you connected to and what number on the BOB? thankyou.
Thanks Ivan!
Your view of pretty cool is quite different to mine. 😄
I would have sparyed freeze spray at the engine computer and see if would stay running that way. If it did then I would take a heat gun to it and see if it stalls out. I do this a lot to jet ski computers.
OEM parts ONLY on these. The skim module is bad and or the key could have failed. Needs a PCM. Rey common. (Did the timing belt skip a tooth?)
Bad ignition switch. Common issue. You did see the TSB for a 1603 regarding bad PCM confirmation test?
Smart decision.
Nice Hat Sir......Looks good on you!
I can see that you constantly missing check engine light on the dash, when the key is on, engine off (security light on)
Why did we not look into the skim immobilizer telling the car to shut down ? Shouldn't we have at least looked at the mode of operation for the skim ?
You are very talented. I love your videos.
Thanks, Ivan
How's the Horses ??
Hi Ivan. I can just hear Keith at L1 AUTOMOTIVE .( DON’T BYE A CHRYSLER )
Customer decided to junk there pt cruiser used to be a very common occurrence. Now they are happily mostly all gone.
I can't believe the owner decide to junk it, unless he just gave it to the repair shop instead of paying the bill
Owner was smart IMO...
@@wyokaiju992 after having all that work done , a use Ebay computer would be a minor cost
i had one of these things same type of faults, it turned out to be a shitty connector to radiator fan was connected and still loose ,inside crappy plastic was cracked were you could not see it took me weeks to find it replaced cam sensor .tightened every ground point . plugs .wires was lost till my hand accidently brushed the stupid connector and it ran . pissed me off after throwing the part cannon at it . all it was was using plastic were you should never had it freaking enginerds.
And this is why I call them the Part-Time Cruiser lol....
The owner is full of it had you find the problem and bought the computor himself......you don't junk a car in that shape
started to sound like a disney film hi low hi low its off to work we go with shovel and a scope
Good call by the customer!
Love the content I would like to have seen that thing be fixed cuz had a PT cruiser doing the same thing had the engine computer replaced from Midas they sent it out and replaced it twice still continue to run and die would have loved to have seen if a computer some other computer would have fixed it
Think the owner made the right choice after making the wrong choice a while back.😉
I have replaced my fair share of PCM's in that vintage of Chrysler. That Pcm design is the weak link.
WHAT ? JUNK THE CRUISER, KRAZY WITH A 5 SPEED & TURBO.
PT Cruisers are known for blowing head gaskets. Turbo PT Cruisers blow them faster.
Did you figure out the problem what is wrong with it
I keep having this problem in my pt cruiser it stalls on freeway doing 60 I shift into neutral starts back up. But if I can't GO 80. IT WILL DIE AGAIN. BEEN DRIVING IT LIKE THIS FOR MONTHS. But when I hook up the computer to it I see when it happens the auto shut off switch goes from high to low and shuts it off. Also the ignition switch is low. Help 😢
Is there an immo control unit on the pt ?
And how you excluded reprogram a key for it might solve it ?
Thanks
I wish I had the tools you have..
I have that on my verso every now and again it will set an immobiliser system malfunction and will just not start you have to turn the key off then on then it starts no problem those systems can be annoying sometimes
“Ain’t got no gas in it” Umm hum…Carl
Pt cruiser based on a dodge neon if you remember those not good.
Before I watch. I'm calling a failing timing belt.
Junk it. Yeah baby. My son's next door had a PT Cruiser that my son could have if he could fix it we ultimately found the TIPM was bad. The neighbor ultimately junked it too.
The computer could decide the car can't run because of lack of control data, set the light and stop talking to modules because it is in no start mode. Though not talking to diagnostic equipment would be a smoking gun that the computer is bad because you have to talk to diagnostic equipment to solve the problem, it doesn't have to talk to module if it knows the car is broken but it has to tell the tech what is wrong. Seems in good shape unless it has other serious mechanical issues, fixing the electrical issues would leave you with a decent car worth several thousand.
First things first. Visual inspection. Is it plugged in? Okay. Plug it in...
I still wouldn't have junked the car unless there were more issues
Привет, Иван! Возможно, я что-то не верно понял или ... Ты выяснил, что имел ввиду Кейт?
@13:35 where is the 4th pcm connector? Or connector is that for the automatic version
DOES THE CAR HAVE GAS?????? THE GAUGE LOOKS MIGHTY LOW.
I showed fuel pressure at the end, it was good
