SES light comes on after a few minutes
Hey guys, got a weird issue here.
In my 94 Z28 after a few minutes of driving, around 10 or so, the SES light comes on as well as the fan on full blast, I can hear it from inside. The car is only around the 1/4 mark when this happens. Any ideas what it could be?
Thanks

Exactly what part of "The car is only around the 1/4 mark when this happens"? The coolant temp gauge?
The fans run because a code is being set that turns the fans on as a protective measure. Scan it.... you will have your answer.

Well I bought an Actron CP9145 scanner, this thing is awesome, I love this thing!
UPDATE 5/21/11:
Code 63 Right Oxygen Sensor (Bank 1 Error) - Replaced the drivers side (lol), need to still replace the passenger's side, need some help on how I should get up in there to take it out!
Thanks everybody for your help so far, greatly appreciate it.

Re: SES light comes on after a few minutes
Start by looking at the wires running down the inner fender that are wrapped with silver foil. When headers are present, the wires get cooked under this wrap and then split. I been there. BTW what does the car is at the 1/4 mark mean? Temperature?

Yeah temperature. Coolant temp is around 178-180 according to the scanner. Engine light just seems to come on after about 10-20 minutes of driving.

I'll check out the fuse for it first. So it's the Bank 2 oxygen sensor? Weird cause it said Bank 1. Thanks for your help guys.

Re: SES light comes on after a few minutes
I had the same thing happen - come on after a few minutes - fans on - temp not moving ever hotter than 1/4 - turned out to be the smog pump which the dealer replaced for free on a 1995 z28 because there was an open recall on it!
after that, SES light has never come on

But there's no substitute for a scan that works.

Yeah it was 63, I'm just gonna have to do the passenger side as well. Any tips for getting to it? I took a look and it looks like a pain in the *** to get to.
