Camshaft Position (CMP) Sensor Inspection
CMP (Camshaft Position) Sensor Inspection1. Remove CMP sensor.
2. Check the following.
- 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.
3. Check CMP sensor as follows.
If faulty condition is found, replace CMP sensor.
a. Connect battery (1) and ohmmeter (3) to CMP sensor as shown in figure.
b. Check that CMP sensor resistance varies as specified below by passing magnetic substance (iron) (2).
If faulty condition is found, replace 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 ohms (ON) and infinity (OFF)
