Anyone have a link to the troubleshooting procedures for codes for our cars. I have 4 codes right now and would like to test the various components related to these codes, not just start replacing parts as it could be something else other than the part that is bad. Currently have codes P0118, P0154, P0300, and P1153. Any help would be appreciated.

 

Three of them point to the passenger side precat 02 sensor, the other is an ECT sensor code. Try gearchatter.com

 

thanks for the website, that is exactly what I was looking for. Off to go testing now.
