My CEL has been coming on lately. After several days it resets itself. Recently got a code reader. On 8/25 my CEL came on while on a day trip. Got codes P1072 which I believe is faulty signal in throttle unit, and code P 1017 ECM internal fault. I drove about 200 miles that day and when I got home to plug in the code reader the CEL went off. Drove it today and the CEL came on with code P1005. I can not find a description of this code. Any ideas what is going on? My suspicion is the ECM is going.

 

Did you have the recall software for the throttle body done yet?

 

Tech,
Yes the software was updated and the throttlebody replaced in Feb. due to malfunction.

 

I have only seen maybe 1 or 2 ECM's go bad I doubt that is it.
But not sure where to tell you to look. I couldn't find the code either.

 

Thanks for looking. I have already had one ECM replaced a few years back. I guess I'm off to the dealer for diagnosis.
