the worst thing for me, its not under waranty after 3 years or 60000km, and not 5 years and 100000km. my jeep is at 95000km and under waranty until march.

im not 100% sure its the computer my problem, i cant buy one only to test and found its not the problem.

do you have any other idea for that problem ? im desperate

I've given you all my information based on the materials I have access to. The tedious part of the diagnostics is testing each wire from the MAF sensor back to the computer. Did you actually take it to a dealership and get them to use the starscan to read the codes and provide you a print out? The starscan is better than any other scanning tool because it can read codes that other scanners cannot read so a dealer printout may give you more information.

If you did get the dealership to do the work so far, I would guess that the dealership would just replace the computer after following the same diagnostic procedure.

By the way, if your jeep runs fine, it just has a check engine light with a p0101 code, you could drive it that way for a long time. Certain features that are inherent in the diesel won't work though, like the remote start and diesel particulate filter regeneration. It would also fail an emissions test if you had to take one.

I'm not sure if used computers for the same make/model/year of your jeep are available at junk yards, but you could try that, usually the computer has to be programmed by the dealership after installing because your VIN and mileage have to be programmed in.

little update, i asked another dealer if the computer was under waranty and they said yes (8 years 160000km). so they tested another computer and after moving a little bit the cable of the computer, the check engine came back. he say its a cable problem, maybe in another cable, not a cable of the mass airflow.

but for now my jeep dont have the check engine... ill wait to see if it come back before to check all the cable of the jeep.

my first dealer is a liar, i wont go here anymore, and it cost me nothing for the computer test, ill go there now.

the interesting thing about the p0101 in the sprinter forum is that the code could be activated any time there is a an air leak in any of the pipes that go to or from the turbo. there are many connection points on the jeep but the main issue has been the turbo resonator, it commonly leaks. the easiest way to see a leak is to check for any oil residue on the turbo pipes because oil will get pushed out the leaking area by air pressure. follow all the piping with your hand and visually check for oil on the pipe. the pipe goes around the front of the engine and finally to the intake manifold.

How did you resolve this problem? I have been chasing down the same P0101 error message. Based on diagnostic test Susieque provided I am up to the point I need to perform the ECM Verification Test Ver. 1 since the voltage test of Pin 4 (K157) of the Mass Air Flow Sensor harness resulted in 5V. Since you tried another ECM and the P0101 persisted suggesting a harness issue, I am hoping you can point me to the problem area before I start pulling connectors and testing each wire. Thanks,

I know the discussion is from 2016.. but who knows!

I have the same problem with pin 4 getting a +5V (same as pin 3)

Did you find the problem?

I'm getting a P0101 soft code. I have no CEL and Jeep runs normally. I can clear the code and as soon as I turn the key on the code shows. I ordered a new MAP sensor, and may order a new MAF as well.

did you get to the bottom of your p0101 issue?
