Linear Air-Fuel Ratio Sensor Check

LINEAR AIR-FUEL RATIO SENSOR CHECK







1. Disconnect the linear air-fuel ratio sensor connector and connect special tool MB991658 to the connector on the linear air-fuel ratio sensor side.
2. Measure the resistance between terminal No. 2 and terminal No. 3.

Standard value: 2.3 - 4.2 ohms [at 20 °C (68 °F)]

3. If the resistance deviates from standard value, replace the linear air-fuel ratio sensor.
