Detect the resistance of the sensorWhen the engine temperature reaches normal, unplug the wire connector of the oxygen sensor and use a resistance meter to detect the resistance between the oxygen sensor terminals. The resistance value should meet the requirements of the specific model standard value (generally 440Ω) |
Detecting oxygen sensor voltageUse the fault diagnosis instrument to detect the engine, extract the fault code, and observe the data stream. The operation of the oxygen sensor is judged by the magnitude and frequency of the voltage change of the oxygen sensor. If it is working properly, the voltage should be between 0.4 and 0.6V. If the voltage is always at 0.45V, the oxygen sensor will not work |
Observe the color of the sensor probe
