I have a 02 envoy and the engine
is idling low. I connected my code reader and it's getting a linking error. I noticed that the warning lights don't stay on when the key is in the on position. What do I have to do to get the odb II port to send data to the reader?
JA: The mechanics have tons of experience in that area. Do you happen to have the code?
Customer: I can't pull any codes because the odb II port is not communicating with the code scanner.
JA: I'll pass this info along to the Chevy Mechanic so that he can get you a quick fix. Are you hoping to fix this yourself?
Customer: Yes I am.
JA: Great! What have you tried so far?
Customer: I've checked the odb II port for broke wires or unattached pins. Cleaned the throttle body, did a etb relearn procedure, and checked some vacuum hoses.
JA: Is there anything else important you think the Chevy Mechanic should know about your Chevy?
Customer: Just the info I gave you.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Chevy Mechanic about your situation and then connect you two.
