The camshaft position sensor (CMP) is a variable reluctance sensor that is triggered by a high point on the left-hand exhaust camshaft on the 2.5L engine and a high spot on the intake camshaft on the 2.0L engine. The CMP sends a signal relating camshaft position back to the PCM which is used by the PCM to control engine timing.
- Check voltage between the camshaft position sensor terminals PWR GND and CID.
- With engine running, voltage should be greater than 0.1 volt AC and vary with engine speed.
- If voltage is not within specification, check for proper voltage at the VPWR terminal.
- If VPWR voltage is greater than 10.5 volts, sensor may be faulty.
REMOVAL & INSTALLATION
See Figures 1 and 2
- Disconnect the negative battery cable.
- On 2.0L engines, remove the air intake resonator.
- Unplug the connector from the CMP sensor.
- Remove the retaining bolt and remove the CMP sensor.
- Ensure the CMP sensor's mounting surface is clean, and the sensor's O-ring is in place.
- Install the CMP sensor and tighten the retaining bolt to 13-17 ft. lbs. (18-23 Nm) on the 2.0L engine, and 71-106 inch lbs. (8-12 Nm) on the 2.5L engine.
- Plug the CMP connector in.
- On 2.0L engines, install the air intake resonator.
- Connect the negative battery cable.
