So it was very cold 20 degrees this morning, so I went out to start the car and let it warm up the the garage. I started the car and it stalled, so then it started up on the third try and seemed fine. But when I came out to go to work the CEL was on! I get to work and run the OBDII and it throws two codes the first code is P0128 which it does every winter so I am use to it. Its a thermostat code that I have been getting since I put in the cooler thermo always happens once or twice the first of the real cold weather. But then there was another code P1689 throttle control electronic monitor???? I reset the codes and the was fine, it never ran funny on the way to work or during work!!! Anyone might know why I might have thrown this code??

 

I didn't catch what year you have but 2002-2004 Bentley calls it an "electronic throttle control monitor level torque calculation error" (?).
Did the code ever come back? Did you "pump" the gas while trying to start it? I had a CEL throttle position sensor after I undid my DME and didn't get it back together correctly. Re-hooked it up, cleared the code and has never come back. Hopfully you will have the same luck. Anyone else got anything?

 

What type of ODBII code readers are you using that let's you clear codes?

Thanks...

 

Local Autozone does it here.

 

I have a Peake Scan/ reset tool I got from Turnermotorsports.com. Great tool save you big $$$ I think it was like $129

 

I "was" having trouble starting the car , maybe I did pump the gas not sure. Has not come back since I reset it!!
