Service Engine Soon Light

[bkelley112]

How long do the codes that are posted from the SES light stored? Is it x number of ingnition cycles or is it stored until cleared? The other day I had the SES light come on and I was able to pull the code. It is P0335 Crankshaft Position Sensor A Circuit Malfunction. The SES light has went out on its own but I want to take it to the dealer to have it serviced and I don't want them to tell me the code is no longer there.

Thanks,
Brian

Brian,

Not sure if this is related to your problem but see the following GMTechLink article.

I think that depends on the code, i.e. if you run out of fuel (or your fuel cap is loose - air leak) you will throw a code (SES) for several ignition cycles, but it will go out after refueling and cycling a couple times. If you throw a code due to trans issue (like a clogged filter)it will be there until cleared. Personal experience.
