Hi,

I am the one that posted “Strange problem in my jeep”

Here is the post:
viewtopic.php?f=5&t=58229&p=657031#p657031

After several mails I actually fix the jeep. Thanks to Jim that bought me a used ECM for my jeep. And thanks to Keith that programmed the ECM. They are the best. Thank you very muchhhhh.

The jeep started to work perfectly after changing the ECM. Actually the jeep is having the initial fail.

I connected the scanner and this is the fail:

Manufacturer controlled fuel and air metering (code number:P1267)

This is why the mechanic that fix my jeep emulate the signal of the MAP and after putting a trimmer (variable resistor) that makes interference in the PCB the ECM started to fail .

When the check light turns on the jeep starts to fail (the turbo doesn’t works any more) and the jeep is turn to emergency mode (go home mode).

I am writing if anyone can help me with this new problem


Thanks

In what country do you reside?

P1267 is a failed #4 cylinder glow plug. It should not cause a limp home mode. The scanner used may not read all the codes, can you try a different scanner? You can easily check the glow plug resistance to verify it is failed. There is a 4-way connector on the side of the intake manifold, unplug it and measure the resistance of each terminal to that of ground. A good glow plug will be around 0.7-1.0 ohms and a failed gp will have a resistance over 200 ohms.

Hi,

Well, I check the resistance of the #4 glow plug and is in 56 ohms, and the others are in 0,7 ohms, so the #4 glow plug is not working fine. I will change it on Friday.

But now I have a new fail. I used my scanner and this is the fail:

Manifold absolute pressure or barometric pressure circuit low input (code number P0107)

I know this code appears when the signal of the MAP is lower than 0.25v. Probably this is because the MAP sensor is not working fine, but there are other reasons that can make this happened.

I change the MAP sensor once in this jeep(not me, so I don’t know if I have the one that goes in this jeep). I need to know the part number of the MAP sensor, so I try to find the original one.

Thanks

If your not doing the ORM you have to pull and clean the MAP sensor every so often. Some here do it at every oil change.
