Thank you. That gives me the encouragement to dig more things out like how to use the system diagnostic and setting port on the below right of the steering wheel.

Your welcome. If you have a good scan tool diagnostic work is much easyier.

Do anyone know how to fix a error C1245 I'm having trouble fingering out this site. That's why I post this a reply. If anyone could point me to the right direction that would be wonderful

Thanks for posting this rustyballs.
I have a 99 alero and do not know where the obd port is. I have looked under the dash by my knees where it is on all my other cars and it doesn't seem to be there. I have searched online and haven't been able to find a location for it there either. Do you have any idea where the obd port for a 2.4L 1999 Alero? Thanks for your help. |
Block sensor
P0325-Knock sensor circuit malfunction
where do I locate this knock sensor to replace it? my car is a 2004 Oldsmobile Alero |
