Description & Operation
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.
