2008 Impala - False OBD II codes
Hello all, anyone have a issue with trouble codes and warnings being displayed on a 2008 Impala but they really don't exist? I get a low oil press. warning, Engine Hot, shut AC off, etc.
But none are true! The low oil press switch was replaced. still get the code. I even disconnected the wire harness from the oil press switch and the alarm still comes on!
Appreciate the feed back. Thanks
