How to Test the Camshaft Position Sensor?
1 Answers
The testing method for the camshaft position sensor is: 1. Use a multimeter to check the resistance between terminal 1 of the sensor and terminal 62 of the ECU, terminal 2 of the sensor and terminal 76 of the ECU, and terminal 3 of the sensor and terminal 67 of the ECU; 2. Turn off the ignition switch, disconnect the sensor's wire connector, connect the positive and negative probes of the multimeter to terminals 1 and 3 respectively, and then test by turning on the ignition switch. The function of the camshaft position sensor is to collect the position signal of the valve camshaft and input the signal to the electronic control unit to determine the ignition timing and fuel injection timing.
