Intermittent SES - ZR-1 Net Registry Forums

gbmidyear66 · 03-03-2012

I have had an intermittent SES problem for a while now - I hoped it would go away when I fixed problem with my throttle body. The throttle body rebuild fixed my Idle problem and IAC - but not my SES problem.

The SES light will go on for about 10 seconds, then go off, only while driving, and only while decellerating (no throttle). It does not show as a trouble code on my Auto-Xray 6000 scanner.

Does anyone have any suggestions / experience on how I might capture what is triggereing the SES? - I was thinking that a PC based scanner might do the trick?

I really hate to admit defeat and have to take it into a professional shop that has the GM scanner tools....
