Camshaft Position Sensor

Print


NOTE
The Camshaft Position Sensor (CMP) is only outfitted on the 4.6L engine.

The camshaft position sensor (CMP) is a variable reluctance sensor that is triggered by a high point on the left-hand exhaust camshaft sprocket. The CMP sends a signal relating camshaft position back to the PCM and that signal is used by the PCM to check engine timing.

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 sprocket. The CMP sends a signal relating camshaft position back to the PCM which is used by the PCM to control engine timing.

Fig. Testing the VPWR circuit of the CMP sensor

  1. Check voltage between the camshaft position sensor terminals PWR GND and CID.
  2.  
  3. With engine running, voltage should be greater than 0.1 volt AC and vary with engine speed.
  4.  
  5. If voltage is not within specification, check for proper voltage at the VPWR terminal.
  6.  
  7. If VPWR voltage is greater than 10.5 volts, sensor may be faulty.
