Oxygen Sensor (Front), OEM

Oxygen Sensor (Front), OEM

The purpose of the front O2 sensor is to constantly assess the amount of unburnt fuel in the exhaust, and to feed this info back to the ECU, which modulates the engines’ air fuel ratio. If the O2 sensor response time is too slow, the information being sent to the ECU will be inaccurate, and the result will be a reduction in fuel economy and performance. It can be difficult to accurately pinpoint a failing O2 sensor before a check engine light is set. If you suspect that your front O2 is dying, but has not yet thrown a CEL, being able to watch the voltage output of the sensor in real time is necessary. This, among a multitude of other diagnostic procedures, can be performed with a Ross-Tech VAG-COM (VCDS) Cable.

This OEM O2 sensor is used in both the driver and passenger side.
