check engine light
 

so my check engine light came on today and i have no clue what to do. ive never had to deal with any of the electronics or computer on any car, so i was wondering how i would go about pulling codes?

never mind...stupid me didnt look in the FAQ first and its the very first sticky

codes are as follows...

12- rpm signal
22-water temp sensor signal
43-starter signal
51-knock control signal in ECU

how do i go about fixing those problems and is there any reason i shouldnt be driving my car right now with those problems?

anybody? please help.

I'd disconnect the pos lead on the battery and clear the codes. These codes don't seem to have any correlation to one another. I'd blame a computer voltage anomaly, or some static electricity, etc. Clear the codes and drive carefully. See what happens.

On second thought, you don't suppose these are all wires contained in a multiplug connector that's come unplugged?

yeah, great advice...clear the codes and act like nothing is wrong...thats what I do! ROFL

but seriously, I wouldnt just ignore the codes, I would follow the TSRM and see what course of action is recommended for solving the issue that threw the code...but hey, maybe thats just me.

ok...well imma do both. im gonna look it up but im gonna clear the codes to see if i get them again. cus i went out tonight and drove it and the light wasnt on anymore. but how do i go about clearing them? do i just disconnect the pos cable?
