Mitsubishi Camshaft Sensor

Check the connection line from the control unit to the sensor using the ohmmeter. Remove the connector from the control unit and remove the sensor, check the individual cables for continuity. A circuit diagram is required for the pin assignment. Reference value: approx. 0 Ohm.

Check the connection lines for short circuit to frame. Measurement between sensor plug and vehicle ground, control unit plug removed. Reference value: >30 MOhm.

Check the supply voltage from the control unit to the sensor. Insert the control unit plug, switch the ignition on. Reference value: approx. 5 V (note manufacturer’s specifications).

Check the signal voltage. Connect the measuring cable from the oscilloscope and start the engine. A square wave signal must be displayed on the oscilloscope.
