SES dash light question
Hello folks,
A few days ago while running errands, SES dash light came on while driving. I got to my next destination and shut the engine off. The next time I turned the engine on, SES dash light didn't come on. A few more stops, along with engine starts, the dash light never came back on.
When I got home, I pulled some codes from my VIN-locked Superchips Micro Tuner. Codes were P0684*, P1636, P0718*, P1107, P1211, and P0603* (In that order). I understand that the codes with the asterisks will set the SES light. I erased the codes from tuner and ran the diagnostic again to see if the codes would come back. That didn't happen.
The next couple of days I ran about 150 miles with no SES light. I got home and ran the diagnostics test again for codes. Nothing.
Does anyone have thoughts on things of what should be checked, or, just call it good and wait for the SES light to come back on and run the codes again?
Thanks,

More than likely it was the P0718 code for the Turbine Shaft Speed Sensor or the P1211 could be the culprit if you were hard on the throttle or you have a bad ICP sensor. Pull the connector off the ICP and see if you have oil in the sensor. If so replace it.
The other codes are not something you would normally get while driving. Ignore P0603 as that is caused from resetting your tunes with the Superchips. You should clear codes every time you change your tune, then you won't see that next time.

I guess my signature doesn't display if using my Iphone. I have a TS 6pos chip for tunes. The VIN-locked Superchips Max Tuner is just kept in the truck for code reading.
Thank you Ken, for explaining the codes, and, giving me leads of what to check out.
