Oxygen Sensor II
Ok guys I have the check engine light on and its the Oxygen Sensor 2. I tried replacing it with the OEM part but I dont understand it since the previous owner had installed a A/F ratio meter. Theres a blue wire hanging from the secondary Oxgen Sensor harness ( I think its whats causing the Check Engine light to go on). It looks like he bypassed that blue wire going into some black wire into the compartment. Might be going to the A/F ratio meter. Am I right ???
