Description






DESCRIPTION

The wide band oxygen sensor measures the oxygen content in the exhaust gas to monitor EGR. The sensor is mounted in the exhaust pipe at a 30 degree angle to prevent the collection of moisture between the sensor housing and element. The sensor is located close to the turbocharger for a quicker response time.

The oxygen sensor has five wires (heater power and ground, reference voltage, and 2 wires for a pump cell). The oxygen sensor connects to a six wire harness connector. A non serviceable trimming resistor is built into the sensor connector. The resistance is dependent on the over all length and type of sensor.
