SES Light Came On

[4drsleeper]

Driving to work this morning and the SES light popped on. I'm assuming it's due to the Stillen HFC's I had installed back in January.

Does anyone know pull a code so I can determine if it's the O2 sensors?

Take it to Autozone...they should be able to tell yo the code.

You can take it to Autozone.

You can also do the stomp test... (much more of a PITA)

Turn ignition on for 3 sec.Press/Depress gas pedal 5 times in 5 sec.Wait 7 sec.Press and hold gas pedal for 10 sec.

Light will start to blink. Count the blinks. All the slow blinks are the first digit. The next set of fast blinks are the next digit... etc

4 digits. 10 blinks means 0.

Well, I got the extenders installed today but the shops scanner was down and they couldn't reset the code. Will it go away on its own or do I have to have it reset at Autozone?

I went to the local "autozone" store and they would not clear any codes. Apparently they got sued about 1 year ago for clearing a code and then somebody had a wreck and blamed it on Autozone for clearing a CEL. Anyway, I disconnected the negative battery post for about 10 minutes and re-connected. I've put about 12 miles on the car now and no SES light. Hopefully I won't have to ever deal with this again.

Last time at autozone, they would not erase the code UNLESS you did something to fix the problem. Same reason I guess. Autozone\Advance Auto scanners get you in the ball park but are not as precise as the dealers diagnostics. good luck
