It is not just diesel powered trucks that have limp mode also gasoline powered automobiles have a limp mode if certain problems occur. It is not fun to suddenly go into limp mode and have very little power.
Another cause for silent limp mode: Your coolant reservoir cap. If your cooling system loses pressure, the first thing to overheat, and rapidly so, will be your fuel. It's why these powertrains come with fuel coolers. Above a certain threshold, your HPFP's performance will be limited/throttled and your truck will limp. The simplest things can be the biggest cause of headaches.
I have a 2002 LB7 Duramax it’s tuned out about 80%. I love my truck. It is my favorite thing in the whole wide world .My transmission is going out what kind of upgrade transmission wise do I need to achieve 1200 horse and how much will that cost me?
Well I’m having a incorrect gear ratio 5th gear on my lly 220hp over stock pushing roughly 525hp and I’ve not ran it hard since those codes and stuff happened for just a 800hp tranny labor and all $9,500 in nc
I had message on filter cleaning on my lmm. I drove the damn thing for an hour on highway. Would not come out of cleaning mode. Ended up being the K&N filter caused the Mass airflow the misread due to the oil. Put stock GM filter back in and all was well.
My 2009 6.6 LMM Has gone into limp mode Only on start up, Twice sense ive owned it, both on very cold days -25c or worse. 1 time the error code read Service Exhaust System, i cant remember the other error message, but both messages went away on their own & i took it to the dealer to get proper service done
It’s a little off topic but if it’ll save somebody from pulling their hair out like I did I’ll gladly take whatever chastising I have coming. My 2004 Duramax LLY started going into derate very sporadically. The only power enhancement it has is a Banks Ram air intake. Ultimately however,it ended being one of the two batteries being junk. I replaced them when I had to jump start the truck everyday. That was 3 years ago and it hasn’t derated once. Prior to that I had scanned it for codes and everything was pointing towards a pressure control solenoid fault so I decided to replace the batteries and then tackle the Transmission issues but after replacing my batteries the check engine light went away, the codes went away and I haven’t had a problem since. I later spoke with a GM dealer tech and he said that one bad cell in a battery can cause the entire electrical system to do some weird things. Which I was partially aware of but I never would’ve guessed it would affect the transmission system but it can and will he said. Those junk batteries weren’t more than six months old but they were cheap John Deere batteries So despite still having a warranty on them, I said to hell with that and replaced them with NAPA batteries and they’ve been great.
@@Duramaxtuner replaced alternator. Both batteries dead, decided to remove them to charge them separately. Long story short. Small side terminals looked clean, no corrosion visible. BUT.. removing the small terminals both positive terminals were full of corrosion. Lots of soda an water toothbrush an pocket knife. Fully charged cleaned replaced. All is good. Transmission is good. Also windows power up fast, air conditioning fan blowing better. Those small side terminals are sleepers. I highly recommend checking yours. You cannot see the corrosion externally. Could probably saved myself 200 bucks if would have cleaned batteries posts a year ago. Thanks for reply hope this helps someone.
5:40 ... how did you know me so well? I have PPEI tunes, jumped to the 60+ after running the 30+ for a week or so. Driving up a paved hill, tow/haul on, traction control off, felt sluggish so I throttled down to get up and over the hill. 0:19 is exactly how I felt! P0733 - incorrect 3rd gear ratio. Scared the shit out of me. Thought I fucked up the trans. My take, too much torque being sent, trans tried to down shift & missed or popped out so save itself. At least I hope. Now I'm scared to get on the throttle while it's approaching 2-3 3-4 & 4-3 shifts... damn that expensive trans tune file.
So how has it been I got my set at 5 220hp time yes I know stick trans pay to play but it’s never done that got a incorrect 5th gear ratio. Pulled over wouldn’t shift to any gears just revs up turn off them back on been great since. But I’ve been running stock I’m just scared to death I screwed up before I got my bank account right for that near tranny
@@Duramaxtunerwe do a pre-trip inspection every morning and never have had any leaks. We found a small hole where it looks like someone did a questionable weld repair prior to us owning the truck and it failed there. I initially thought head gasket so I need to check that also. All signs lead to 💰
Just deleted my 05 lly it ran great no check engine light then I started going down the highway and got into higher boost and it sounded like air was escaping from somewhere didn’t and the check engine light for low performance supercharger not sure if it’s the up pipe or a boost leak
I have a stock 07 LBZ, 118,000 miles threw P0713 and P0708 deleted the codes and now P0708 keeps coming back, only when moving the gear selector into gear, CEL comes on, and light under the selected gear disappears as well as shifts sloppy through PRND and locks into 3rd gear I believe. When the code is deleted it runs fine, the internal wiring harness was changed 3,000 miles ago due to a similar problem when fluid was leaking into the plug. I use this truck daily for my business towing trailers, I’m concerned it’s going to strand me if I don’t get this figured out.
My lb7 won’t shut off with key when I shit the key off everything stays on and it throws a bunch of codes has a glow plug modgel code and that’s it and the box isn’t hot

N Perry all map sensor outputs are usually calibrated between 1.2v to 4.9v with max output of 5v, if the ecu sees 5v it will know either the sensor is failing or the pressure is out of calibrated range and will throw a code

Hi my Nissan navara is in limpmode when I turn it on if I let the truck run for 10 minutes it fine or turn off and turn back on it's fine .no code on the dash could you help me please
Hey how are you? I have mine allison 1000 going in to limp mode. I can get any codes is a motor home I have try a 9 pin diesel scanner but it show just engine Codes. The trans was showing a ⚙🌡 light on the dash right when you turn the key on. Some sites said the pressure manifold should be defective. I had put on new manifold, internal harness, filters and mobile delvac. And it came back after 10 mins drive. Do I need to clear codes on the tcm after the manifold get replaced? How can I do that is there is no connection between 9pin j1939 connector and the trans? Thanks for your feedback. Trans have just 32000 miles. Engine show just 1100 hours .
I've had trans fluid a leak for a while out of the bellhousing. I forgot to check the level over the past week. Now it got so low im in limp mode. I pulled over and put fluid in but still stuck in limp mode. Tried cycling the ignition, cycling the gears with the truck off. Its stuck in limp mode. I have efi live flashscan v2 but haven't really used it yet. I haven't got around to egr delete yet - thats why I got it. And, I don't really know how to use it. But could I reset it through efi?
i have a 2016 cheverlot silverado HD 3500 6.6 duramax diesel that has the cp4 injectot pump been trying to find someone to take it off heard horror stories !!! does anyone now if GM has any recalls or special policies or offer any assistance to take this pricey bad pump off put a cp3 on? any information would be appreciated thank you in advance!!
GM wont be helpful on that. They offer a CP4 replacement for CP4 failures. There are 2 aftermarket options. The CP3 from SS Fuel and the 10mm Cp4 from Exergy are the only real options out there.
HI Nick, getting codes p1723 and p1721 on a 2001 Sierra 2500hd. Engine light is currently on but the previous guy put too short of a filler neck on it and it has no gas cap. The truck stays in 3rd gear but there is no rpm limit. It shifts through 1st and 2nd fine. The truck does have some kind of programmer with 10 siding and a dial turn but I just picked this up so don’t have much info on it. Do you have any ideas of where to start ?
Will I be able to read codes even though I don’t have a check engine? My 2003 duramax doesn’t have any power! If I hit the pedal, it revs high and starts to slow down like crazy. I have to lay off and slowly keep pushing the pedal so it tries to hit 60 mph.
Sounds like a trans build is in your future. Cruising on the highway generally does not cause a P0700. However in the city going from light to light, that is when we see more problems.
I have a c5500 I did a egr delete no tuned I have a limp mode codes air mass flow sensor. I have a scanner I deleted and keep driving but is annoying any ideas what to do?
i have the same experience with my 2009 6.6L i recently tuned it and whenever i floor it 100% the truck goes into limp mode check engine lights comes on and it tells me to change the fuel filter. when scanning the codes they are related to 1. low fuel rail pressure 2.throttle body sensor. i am wondering what are the ways to fix this issue because in long term it can cause more problems. any suggestion is appreciated. thanks
@@Duramaxtuner so your saying to change it with an aftermarket one or buy new stock ones? i am thinking the new tune is running higher fuel pressure and the stock fuel pressure relief valve is not made for that and thats why i am getting the error low fuel rail pressure error.
@@reshadamiry8639 We always start with accurate diagnostics. the aftermarket plug does not allow any return through the high-pressure rail. This will give you a more clear baseline for further testing. duramaxtuner.com/lbz/supporting-modifications/fuel-pressure-relief-valve.html
Yes it dose it will read all d.t.c for 1996 and newer with obd2 port and it will let you run data logging as well you do need a windows based software to be able to send the log to someone or to read it hope this helps good luck

Buying my 4th pickup but 1st diesel. I’ve learned a lot watching you channel. Really appreciate what you’re doing and live the Facebook post joke. 😁
Right on!
It is not just diesel powered trucks that have limp mode also gasoline powered automobiles have a limp mode if certain problems occur. It is not fun to suddenly go into limp mode and have very little power.
Another cause for silent limp mode: Your coolant reservoir cap. If your cooling system loses pressure, the first thing to overheat, and rapidly so, will be your fuel. It's why these powertrains come with fuel coolers. Above a certain threshold, your HPFP's performance will be limited/throttled and your truck will limp. The simplest things can be the biggest cause of headaches.
I have a 2002 LB7 Duramax it’s tuned out about 80%. I love my truck. It is my favorite thing in the whole wide world .My transmission is going out what kind of upgrade transmission wise do I need to achieve 1200 horse and how much will that cost me?
You'll definitely need a beefy torque converter. We have the DT 1000 for 1000 HP + trucks and it comes with a Goerend triple disc torque converter.
Well I’m having a incorrect gear ratio 5th gear on my lly 220hp over stock pushing roughly 525hp and I’ve not ran it hard since those codes and stuff happened for just a 800hp tranny labor and all $9,500 in nc
If your truck is stuck in 1st gear and the gauge cluster isn’t working, check fuze ing 0 in the interior fuze box
change filter when fuel pressure is low , that's the cheapest first

Dude this happened to me doing about 100 scared the absolute fuck out of me
I have an lb7 and when I tow I get a overboost code, if the MAP sensor only reads up to 22psi how exactly does it sense overboost always been curious
N Perry all map sensor outputs are usually calibrated between 1.2v to 4.9v with max output of 5v, if the ecu sees 5v it will know either the sensor is failing or the pressure is out of calibrated range and will throw a code
Hey man I have a 2008 3500 6.6 duramax I am in limp mode , I ran the diagnostic and I have the turbo booster and fuel pressure regulator is a code popping up , what do you think is going on ? Trouble codes are p0090 and p0047
Mine is Underboost , any answers ?
Any trick to get the check engine light off
Usually u cycle the ecm by turn key on and off three times. After a day or two the check engine should go away or if u have a monitor like a cts and delete the codes
05 LLY. P07300 and P0735. Tow haul on pulling camper up hill 3/4 throttle. Tunes were on towing. and It slammed it into 4th gear. What should I do to prevent?
Sounds like you need to upgrade to a built transmission.
@@Duramaxtuner definitely agree. Found out it went into limp mode because I had too hot EGT’s etc. gonna have to mess with my tow tune a bit.
Why is my lb7 not going past 90 mph
My trucks worst nightmare the dreaded p0087, balance rates on injector 4 are bad. Never thought the lbz had injectors but I guess I'm unlucky 😭😢
Additionally, it didn't not down shift , just lost power.
My lb7 will go into limp mode, I lose reverse and get stuck in 3rd tell I pull over and cycle the key. The only thing that comes on is the service engine soon light, I have never seen the check engine light. I have tried to still scan it and there’s no codes. ?!?!
Sounds like clutches slipping, you may need a more advanced scan tool to see TCM codes.
@@Duramaxtuner hey thanks a lot, after reading a lot and doing some research I think I will just call my buddy at SDP and have him build a transmission for me.
05 lly 420k miles new motor 100k miles ago egr delete full intake with mouthpiece and full exhoist stock tune pulling a po700 and po776 code it did it anothet time and said speed sensor I'm confused truck dont slip jerk nothing o that nature guessing trans is jus on its last leg?
2012 2500 Duramax with cleaning exhaust filter on dash and in limp mode. Drove it 70 to 80 miles and no change. Any ideas?
You probably need to start with a manual regen.
So I have an 05 lly equipped with the zf6 trans. It acts like it goes into limp mode while pulling mountains. Doesn’t show any codes at this time. But it’s like a daily thing, truck gets a little Smokey and seems like the throttle doesn’t respond when I push it to the floor. Truck had the codes P0101 and P0299 so I cleaned MAF sensor and rese the codes. Still having the same issue. Truck is stock including stock catalytic converter and muffler and EGR valve. Once I peak the mountain it takes off like a raped ape again but still Smokey till I let off throttle. Anybody able to help me?
My truck just went into limp mode. EFI LIVE tune 4, 80hp tune. It locked itself into 4th gear and of course the check engine light came on. I pulled over and cut the truck off and put it in lvl 3 (60hp tune) and it drives fine and shifts fine but my check engine light is still on. How ccan I get the engine light to go off?
clear the DTCs. I can do it either with autocal or a CTS2 edge monitor I have.
Hi my Nissan navara is in limpmode when I turn it on if I let the truck run for 10 minutes it fine or turn off and turn back on it's fine .no code on the dash could you help me please
I'm not getting codes when mine does it it happens when heavy on the pedle
@kylemarks1947 That sounds more like a specific engine issue than limp mode activating.
My 2008 gmc duramax went into reduce power.plugged in and had 4 codes,p003a,p0102,p2563,p04041,and has banks 6/1 tuner is this serious.
Yes take it to the scales ive been there before
Serious like how? Bad turbo?
Hey how are you? I have mine allison 1000 going in to limp mode. I can get any codes is a motor home I have try a 9 pin diesel scanner but it show just engine Codes. The trans was showing a ⚙🌡 light on the dash right when you turn the key on. Some sites said the pressure manifold should be defective. I had put on new manifold, internal harness, filters and mobile delvac. And it came back after 10 mins drive. Do I need to clear codes on the tcm after the manifold get replaced? How can I do that is there is no connection between 9pin j1939 connector and the trans? Thanks for your feedback. Trans have just 32000 miles. Engine show just 1100 hours .
You likely need a scanner that can communicate with the TCM to properly diagnose your issue.
i got u0402 code not communicating with tcm. do i just change transmission control module.
I got a ambulance with 6 6 duramax replaces the pedal 3 times still get the same code
sooooo, did you finally find a cure you could share?
2010 Hyundai Santa fe goes into limp mode while trying to over take on the highway, no trouble code. What to do?
Trade it in for a Duramax.
I've got a 2012 ram 3500 6.7 with a 68rfe will the trans be a definite fix if the code is P0734? I needy truck back on the road asap.
What was your problem what happen that u ended up doing
Sold it lol got tired of fooling witb it didnt have the money
Is their a way to tune your transmission, to accommodate for some of the power from a "big tune"?
A TCM tune wont make your transmission able to handle more power. It will make a built trans shift better.
@@Duramaxtuner thank you, just wanted to know
I 2002 lb7 duramax showing p0380 help please
Nice truck
I've had trans fluid a leak for a while out of the bellhousing. I forgot to check the level over the past week. Now it got so low im in limp mode. I pulled over and put fluid in but still stuck in limp mode. Tried cycling the ignition, cycling the gears with the truck off. Its stuck in limp mode. I have efi live flashscan v2 but haven't really used it yet. I haven't got around to egr delete yet - thats why I got it. And, I don't really know how to use it. But could I reset it through efi?
I dont have check engine light on. Just the trans symbol
Nissan patrol zd30 wont give power even after stepping on the accelerator at max yet same as stepping lightly 😭
i have a 2016 cheverlot silverado HD 3500 6.6 duramax diesel that has the cp4 injectot pump been trying to find someone to take it off heard horror stories !!! does anyone now if GM has any recalls or special policies or offer any assistance to take this pricey bad pump off put a cp3 on? any information would be appreciated thank you in advance!!
GM wont be helpful on that. They offer a CP4 replacement for CP4 failures. There are 2 aftermarket options. The CP3 from SS Fuel and the 10mm Cp4 from Exergy are the only real options out there.
I have a 03 lb7 keeps throwing PO708 and have tried about everything anyone have any idea what it could be
p0700 codes are typically transmission codes. Take it into a shop!
Have a code that keeps popping up P2263 on a 2016 Silverado 3500hd need help...
Do you have the stock turbo?
HI Nick, getting codes p1723 and p1721 on a 2001 Sierra 2500hd. Engine light is currently on but the previous guy put too short of a filler neck on it and it has no gas cap. The truck stays in 3rd gear but there is no rpm limit. It shifts through 1st and 2nd fine. The truck does have some kind of programmer with 10 siding and a dial turn but I just picked this up so don’t have much info on it. Do you have any ideas of where to start ?
Both are transmission codes, have you data logged the truck?
08 LMM h&s tow tune delete dpi egr. When pulling loads or in high idle for extended period code P0193? HELP PLEASE!
Some pretty good info here: www.duramaxforum.com/forum/11-16-lml-duramax-powertrain/829449-p0193-code.html
Will I be able to read codes even though I don’t have a check engine?
My 2003 duramax doesn’t have any power! If I hit the pedal, it revs high and starts to slow down like crazy.
I have to lay off and slowly keep pushing the pedal so it tries to hit 60 mph.
Did you happen to figure out what the problem was? My 05 is doing the exact same thing right now.
Fuel filter. Hope no one convinced you it was injectors.
Wher are yall located?
I have a 2005 duramax 4x4 LLY with a P0700 duramax {transmission control system..
Sounds like a trans build is in your future. Cruising on the highway generally does not cause a P0700. However in the city going from light to light, that is when we see more problems.
One reason limp mode gets activated....my ex wife
I have a c5500 I did a egr delete no tuned
I have a limp mode codes air mass flow sensor.
I have a scanner I deleted and keep driving but is annoying any ideas what to do?
Tune it.
@@Duramaxtuner Any suggestions
What kind of scanner do you have to delete or reset it ?? I need one
i have the same experience with my 2009 6.6L i recently tuned it and whenever i floor it 100% the truck goes into limp mode check engine lights comes on and it tells me to change the fuel filter. when scanning the codes they are related to 1. low fuel rail pressure 2.throttle body sensor. i am wondering what are the ways to fix this issue because in long term it can cause more problems.
any suggestion is appreciated.
thanks
Start with a Fuel Pressure Relief valve.
@@Duramaxtuner so your saying to change it with an aftermarket one or buy new stock ones?
i am thinking the new tune is running higher fuel pressure and the stock fuel pressure relief valve is not made for that and thats why i am getting the error low fuel rail pressure error.
@@reshadamiry8639 We always start with accurate diagnostics. the aftermarket plug does not allow any return through the high-pressure rail. This will give you a more clear baseline for further testing. duramaxtuner.com/lbz/supporting-modifications/fuel-pressure-relief-valve.html
Hey i have a code P268A and makes my truck stay in limp modes goes thru all gears but wont go over 2k rpm it my worl truck need help asap

Hey nick I have a question about the edge cts monitor, does it read trouble codes?
Yes it dose it will read all d.t.c for 1996 and newer with obd2 port and it will let you run data logging as well you do need a windows based software to be able to send the log to someone or to read it hope this helps good luck
#### #### thanks man
Yes it does.
P0777 and p0700
MAF over range LB7
Are Diesel engines worth it due these interruptions?
Yes. Anybody who tows, knows.
