How Do You Change A Narrowband O2 Sensor Over To A Wideband Sensor?
A narrow band O2 sensor is used primarily for tuning the air fuel ratio in your vehicle. The factory O2 sensor’s purpose is to measure the amount of air and fuel being mixed in the throttle body. It does this indirectly as a sort of “backup” system to the throttle and intake system. By measuring the exhaust gases, it can tell how much air and fuel was in the combustion chamber. A wideband O2 simply measures a wider range of air to fuel mixtures and allows you to tune the engine for a custom racing application. Place the jack under the front jack point and lift up on the vehicle. Place jack stands under the front pinch welds of the vehicle. These are normally located directly under the front driver and passenger side doors. Lower the vehicle onto the jack stands. Climb under the vehicle and locate your O2 sensors. There is one before the catalytic converter (the elongated, enlarged “egg” inline with your exhaust tubing) and one after the catalytic converter. Unplug the electrical connec
