Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hi. What engine is in your ION and what code was retrieved from the computer?
It is a 4cyl, but is it a 2.0, 2.2, 2.4? What code was retrieved from the computer?
Give me a second please. I need to pull up my service manual.
Ok thanks. GM does have a service bulletin related to retrieving APP codes p2138 due to water intrusion in the instrument panel harness. I have seen this problem set p2128 as well.
The repair is to Locate the IP to body harness connector, which may be located in and around the left hand kick panel area or inside the IP and check for water intrusion.
This may be what you are having going on, since the APP sensor was replaced and the problem is reoccuring.
I can send you an offer for the service bulletin in savable, printable, PDF format if you are interested.
Hi. Have you made progress with your Saturn? Were you able to find the source of the APP code? Please respond to let me know your progress and to rate my service. Thank you.
