CMP Sensor Inspection

Reference: CMP SENSOR REMOVAL AND INSTALLATION 

1. Check the following points:
   • Check that O-ring (1) is free from damage.
   • Check that end face of sensor and signal rotor tooth are free from any metal particles and damage.

2. Check CMP sensor as follows.

   If faulty condition is found, replace CMP sensor, see CMP SENSOR REMOVAL AND INSTALLATION .

   1. Connect battery (1) and ohmmeter (3) to CMP sensor as shown in figure.
   2. Check that CMP sensor resistance varies as specified below by bringing magnetic substance (iron) to CMP sensor.
      NOTE: Be sure to keep approximately 1 mm (0.03 in) gap "a" between magnetic substance (iron) and end face of CMP sensor.

      CMP sensor resistance 

      Resistance varies between less than 220 Ω (ON) and infinity (OFF)
