Another PSM worshop message

Recommended Posts

Well, while driving home I got the PSM workshop message. After a couple of minutes of driving, when coming to a stop, it would go very slowly and then finally kick in. Once home, hooked up the durametric. Following codes

470 CAN comfort in signal wire operation

778 Steering signal sensor

1314 DME control module

819 air conditioning sensor open circuit

1336 can comfort off

470 can comfort off

P0700. transmission control implausible signal

P0050 heater control bank 2 sensor test not completed

P2680 fuel pump control no signal

P0011 cam position timing over

P2186 throttle pedal implausible signal

P2174 throttle position implausible

I cleared all codes and only the 470 code remained. I disconnected the negative battery cable for a few minutes and declared using Durametric. Drove fine. After stopping at the store, turning off the car and then restarted the Psm code came back up.

What the heck is going on?

What diagnostic tool you use?I have to ask you to be more specific!So once again, from which modules you read those errors? PSM? Gateway?...You can test all CAN lines from gateway, (using the right diagnostic tool)and see in which line is problem.

Okay, I cleared all codes checked the gateway and really couldn't find anything clear. I limped to my indie shop and they just let me know that they said its the primary fuel pump blowing a fuse and relay. In addition they said the o2 sensor is completely off line. They said due to these issues the psm was trying to compensate. He quoted me $1475 to replace the primary fuel pump, fuel filter, the secondary fuel filter since I didn't replace it when I changed out the pump a year ago, seal ring, relays, fuses, o2 sensor bank 2 before cat, reset and calibrate. I totaled up the parts and came close to 900 so what the he'll I will let them do it.
