I am getting multiple codes (P0113, P0118, P0238) all associated with ecm pin #60. I have replaced the coolant temp sensor and the air intake temp sensor, but the codes remain. Any suggestions?

 

Is there any vaccum leaks?

 

No. I replaced the vacuum lines associated with the turbo.

 

Check all the connections at the intercooler as well.

 

The intercoolant lines and connections are good.

 

What type of scanner are you using to clear teh codes?

 

It's an Innova scanner. No problems clearing the codes. They return after the engine is restarted and the temp gauge is not working on the inst. cluster. All the affected sensors are on the #60 ground terminal.

 

Weird.
Sometimes the scanners won't clear all the codes.
Have you had a tranny installed lately?

 

No. I've had the car approx. 2 months. Other than a new timing belt, no known history prior to this.

 

Dear Tech, I'm sorry, I should've said I don't know.I've had the car approx 2 months.

 

This may sound funny but it might also help.
Run a ground wire from the transmission to the engine and see if it helps.

The cars main ground goes through the tranny.
If something is wrong between the mating surface it might cause these problems.

 

Thanks, I'll give it a try.

 

I ran a ground from the transmission to the engine with no improvement. I also tested the volts and ohmsat the temp sensor, map sensor and intake air temp sensor. They were within range.The temp gauge isstill not working. Ialso noticedwith the car was running that the a/c compressor did not come on.

 

Something is really out here.
Is the computer seeing a temp from the temp sensor?

 

Thanks for your response. I don't know. How would I check that? (output to the central module?)

 

A scanner that reads real time would tell you what temp the computer is reading from the coolant.

 

Tech, Thanks for your response. I think I need to upgrade my scanner. I do have a question. The VADIS wiring diagram has a connector point 53/319 in the engine wiring harness. The ground wires to involved sensors converge at this connector. Is this an actual connector point outside the ECM ordo the grounds merge a A60 pin on the ECM?

 

When you look up that connector in the pictures does it show the plug?
Somewhere on the program it will show you the location of the connector.

 

Tech, Thank you for your response. I found the connector(actually a junction point). I also checked continuity of all four sensor (from the plug to and after the junction point) ground wires. All were within specs. The signal is getting to theecm from the sensors. I just don't know what's happening in the ecm.

 

Might be a problem with the ECM
