2005 Chrysler T & C (appears to have small break in MAP connector line)

[email protected] said:

I posted concerning codes p0129, p0068, p2074 codes showing up on my van. I took the power steering reservoir off to inspect the lines. I saw what appears to be a very small break in the line. I used electrical tape on it and wrapped up the remaining lines. However, I'm still getting the codes. Do you think a small break could cause the codes? If so, what's the best way to repairing the break?

I have some 18-22 gauge watertight heat-shrink butt connectors that I thought about using (Harbor Freight)? If I splice the wires, will these type of connectors work?

Thanks in advance for your help.

Are you able to remove the wiring harness and repair it off the van or you need to make the repair on the van? If it can be removed I would do that and resolder the connection and use heat shrink tube overtop. The butt connectors would work, but I prefer soldering them (it would be stronger).

First, electrical or vacuum lines?

Second, did you reset the codes after you repaired? Otherwise, it might take a few drive cycles to clear.

You also need to determine whether there is continuity in the wires to the MAP.

I reset the codes. The van is driving alot better, so I will give it some time. BTW, the lines are electrical...from MAP sensor to the engine.

Thanks for responding to my post.

I do have continuity in the wires. As matter of fact when I tested the signal and the ground with the van off it had a reading of over 4 volts. The ground wire tested at .11 V and the constant at 4.96 V.

Thanks for responding to my post.

I am not able to take off the whole harness. I will have to splice the wires and add butt connector to it and heat shrink it. I have added electrical tape but I think that disturbs the connection. The code that pops up shows and maybe a connectivity problem at the connectors, but I'm thinking it's because of the very small break in the line. It's very small.

Thanks for responding to my post.

Problem solved....thanks, everyone.

Thank you for your responses. I ended up taking it to the Chrysler Dealership that couldn't find the problem. They said I must have a short to ground somewhere after keeping my car for 3 days...and charging for additional diagnostics. They said the hand tool wasn't picking up communication. They supposedly went through half of the modules and didn't find the problem. Sorry, got long winded...but another auto repair shop, with the same information I gave Chysler, found the problem within a day and fixed it for less than what Chrysler charged. At any rate, the problem that my signal wire to my map had a short/burned/frayed. They repaired it. Problem Solved.

Once again, thanks.
