Finally got the paper clip stuck into positions 4 and 5 (the two to the far right) and got some codes. Found a link with the codes but wanted to double check to make sure I have the right definitions for the codes that I am getting: 13: Oxygen sensor circuit open or no activity 23: Intake air temp sensor error (low temp indicated) 34: MAP sensor circuit error (signal low indicating high vacuum) These codes sound right? Also is there a way to clear these codes and see what comes back? I have been ignoring the light for several years because the car runs fine (for a 305). As always and help or guidance is greatly appreciated.
