I use a cheap $10-20 bluetooth OBD2 adapter and $5 Torque app for Android. Works great on a phone or tablet. Pretty sure it will do all these tests, depending on what the ECM will allow it to read. I worked in a garage for a couple of years and used a several thousand dollar Snap-On Verus. Torque will probably do about 70% of what the Verus would do.
Thank you for this video.. very much needed. You say you put in a jumper wire at 4:50 With a fuse; what size fuse is that ? Or what size ohm resistor do I use to put a jumper wire on that ? Thanks again.
all of these videos are great , unless like me, your van wont idle and barely runs goosing the throttle, and your OBD scanner/ code reader gives you a version of; "sorry, we're not happy plugged in here" every time you plug it in.
Will a leaky intake manifold cause this sensor to read high or low at idle?I should add I have an old 5.7 Vortec Tahoe. very minor leak and no coolant going into engine at all.

A bad MAP sensor may not allow the car to start at all-it will crank but won’t hold the idle at a level that will keep the engine running; it will just die. While the RPMs are high-say, while cruising down the highway, nothing would happen, but the engine would die as soon as your foot is off the gas AND the RPMs drop. MAF isn’t so severe. My car will start and run with it unplugged. For how long and what problems that might cause I can’t say.
I have a 98 chevy 5.7 vortec pos. Lol. I have the po108 code. Dosent pop up untill the truck either dies or struggles so bad to stay running the tach drops and act like it out of time or running on only 2 cylinders. Wont start back up unless you try really hard but still struggles. I delete the code and in a matter of seconds its back to normal. Will run for 20 kins or so before acting up again. It did this that other day I deleted code and got a week out of it before it acted up again. When it's not acting up it starts hard and dosent start or sound right running but running ok. Know I have done so much t this engine I've changed every sensor wires plug wires cap rotor temp sensor knew MAF brand knew intake. And alot more. I dnt see how this map sensor could cause this am I right?
Wish I knew how to check all that myself ..... I've been having a lot of problems with my car and maybe it's just something as simple as that...my car jerks when driving and makes a weird noise .

If so I'm getting one today looking at the new ones and from cleaning mime I'm sure I don't recall seeing the sane elements that should be present . Likely my issue
I'm looking for a simple fix, my gmc jimmy with the 4.3 vortex sometimes has a long starter start. In the morning it pops off quick. But after it sits for awhile. And then start. It's long. I'm hoping it's not fuel leak in the intake. Please respond. Love to hear thoughts.
its funny, MAP sensors are basically microphones. a diaphragm that changes a voltage range based on pressure waves. wonder if these could be used to detect knocks? i heard some cars have knock detecting microphones in them?
Can the map sensor be bad if at idle when you rev it, it doesn't go up but when you accelerate down the road then it increases finally. It's a Honda element 04. No codes but running rich negative 15 both short and long term. Thanks.
Hi i need help with my MAP sensor wiring harness, i have a civic 9th gen R18z1 I'm facing an issue with the engine hesitation but when i wiggle the wire the hesitation went away however there's no check engine light or any sort of code on scanner,if anyone can help me on this issue I'll be grateful.

Hi, can you tell me if the pressure reading from a MAP should be dead steady or can there be some variation? I have three pressure sensor in a bmw m235i ( ambient pressure, intake charge pressure and manifold pressure). Two ( ambient pressure and manifold pressure sensors) are dead steady at 1030 hpa whereas the intake charge pressure sensor varies between 1027-1033 hpa when using a ODB scanner . All readings are before starting the engine. I'm experiencing a fault code (Throttle valve opening angle absolute pressure intake pipe comparison pressure too high) on startup and was wondering is the MAP sensor which is showing a variating value could be the issue.
You ambient temperature should stay the same, it only varies when the outside atmospheric pressure changes. The MAP sensor will change and vary when you start the engine. Just like in the video.
howzit my MK3 Golf 2lt have short to ground on the MAP sensor connector as per the dio, when i connect the sensor the car just dies even if you hold the rev now i decided to unplug the connector and runs but does not have power i some times have to climb the hill on the 1st gear where can i start resolving this issue
I have a question my car (lifan 320) is facing a problem because of the map sensor , I tried to replace it with another one but I can't find the one that fits my car is it ok to change the socket and pins of the map sensor getting out of the ecu

my check engine light came on after 6 months bummer seeing it on after its been off for awhile the code told me map sensor and some guy at oreillys mentioned my engine cabin filter not sure how he connects that to map sensor will bad engine filter do this im no mechanic so go easy on me lol
So use a computer sensor to diagnose? That’s all? I think there may be other things that would be helpful to know other than “buy a scanner and scan it”

The map sensor basically acts like a brain. It can make your engine run all kinds of funky random ways. My guess is this is your problem

How to diagnose
Step 1 - Buy an expensive scan tool
Nicè
Dude why didn't you show how to take it off?
They literally only have a couple screws , nothing to show . The sensor will have a type of either Teflon or nylon seal or ring . Easy
So use a computer sensor to diagnose? That’s all? I think there may be other things that would be helpful to know other than “buy a scanner and scan it”
