Durango O2 problem
 
Trouble with my mom's 99' durango again. The other day it started to chug and sputter like it was going to stall, then idled up to keep itself running. Engine light came on. Checked codes, got code p0132. Assumed bad upstream sensor so today I changed it. Drove it around a little bit and it did it again, felt like it was going to stall, idled up but when I gave it gas to leave the stop sign I was at, it gutted out for a second or two with no power then finally took off like nothing was wrong. Checked codes when I got home, now it has code P0135 and P0138. I don't get it. Any thoughts?

*EDIT* it only does it when the trucks at a stop and idling, and doesn't do it when it's cold only after it's been driven for a while.

What engine is in the Durango? Judging by the symptoms and codes, I'm inclined to think maybe you have the O2 sensor signal and heater wires shorted together. My second guess is a PCM internal issue. You really need access to a scan tool and DVOM to sort this out unless a visual inspection of the wiring turns up a problem.

It's the 5.9L, I'll trace the harness and see if I can find it rubbing or melting.

You may find these diagrams useful if you decide to use a DVOM to sort this out.

I checked the harness and found no problem. My mom took it this afternoon to a local mechanic, he thinks the exhaust manifold leak ( it's a quiet tick so I thought it wasn't that bad) could be messing with the o2 reading, he thinks it could also be the Idle air control. I'm going to do the manifold gaskets since they need it anyways to see if that solves it. But I don't think an IAC would cause it to throw o2 codes. He says it could be confusing the ecu... sounds like too much of a shot in the dark though.

I think this guy is either incompetent or is trying to take you for a ride. Either way, I wouldn't call him trustworthy. Below are the possible causes for the codes you're getting. I suspect this "mechanic" isn't performing the correct diagnostics by the book and is taking s shot in the dark at it as you stated.

P0135 -

1/1 O2 SENSOR CONNECTOR DAMAGED
1/1 O2 SENSOR GND CIRCUIT OPEN
ASD RELAY OUTPUT CIRCUIT OPEN
1/1 O2 SENSOR FAILURE
1/1 O2 SENSOR HEATER ELEMENT FAILURE

P0138 -

CIRCUIT OPEN FROM O2S CONNECTOR TO PCM CONNECTOR
O2 SENSOR SIGNAL SHORT TO VOLTAGE (ENGINE OFF)
O2 SENSOR SIGNAL SHORT TO VOLTAGE (ENGINE RUNNING)
O2S SIGNAL INTERMITTENT SHORT TO VOLTAGE (ENG OFF)
O2S SIGNAL INTERMITTENT SHORT TO VOLTAGE (ENG RUN)
POWERTRAIN CONTROL MODULE DEFECTIVE

I'm going to have to find a new mechanic I think. It's now stalling on the highway, seems like it just gets the power cut while driving. Sometimes does it at a stop. And it's now throwing codes p0132 and p0135. I'm not very good with electrical stuff and can never figure out how to properly test with a voltmeter.

I wish I could offer more help. Let us know what you find out.

CherryRam 04-04-2013 09:28 PM

About to push this thing off a cliff. We haven't been able to get it to a new mechanic because it wont drive far enough. We'd have to take it to the city and it now stalls when it's warmed up and usually wont restart until it's fully cooled off. Further research online leads me to fear it is the pcm. Can a pcm be tested?

RamTech 04-05-2013 10:12 AM

No there's no way to test a PCM. You'll have to rule out all other possible causes in order to condemn the PCM.
