Hello,
I got too many things going on right now to read all the posts to see if I can get what I'm looking for (sorry). 89 Chevy Full Size pickup with a 305 TBI. Just pulled 2 codes, Code 15 and Code 22. I found a generic list of GM Codes and the 15 is Coolant Temp Sensor (didn't specify Hi or Lo) and the 22 is Throttle position.
I'm cleaning my grounds right now (kinda green) but does any one out there know for sure if these are the correct codes for that year. The odds of 2 sensors failing at the same time is pretty slim, so for now I'm thinking ground issue or possible ECM..
Including a web link would be awesome too...
TIA..
Nick
