Having problems with your Pontiac Cars & Trucks ?
2005 Pontiac Wave 5 How do I change out the O2 sensor. Sensor 2, bank 1.
\015 My 2005 Pontiac Wave 5, 1.6 engine, failed its e-test due to bad O2 sensor. Engine light has been on forever and I guess the mystery is solved now. Was quoted over $250 for the job but I've bought the part online for $25 and I'm hoping to install myself as I've been told its a relatively simple change out. It's bank 1, sensor 1. If anyone here knows the protocol I'd really appreciate it.\015
