96cse:140code CEL. Front or rear O2 sensor? Posted by DickT [Email] ![]() ![]() |
I keep getting and clearing the error with my OBD2. It will go 25-150 miles before it comes on again. Book says 140 means "O2 sensor circuit no activity detected bank 1 sensor 2". Anyone got any experience with this code?
