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.
The CMP sensor detects the position of the camshaft. The CMP sensor identifies when piston No. 1 is on its compression stroke. A signal is then sent to the PCM and used for synchronizing the sequential firing of the fuel injectors. Coil-on-plug (COP) ignition applications use the CMP signal to select the proper ignition coil to fire. The input circuit to the PCM is referred to as the CMP input or circuit. DTC P0340 is associated with this sensor.

Removal & Installation

3.0L (VIN S) Engine

1. Before servicing the vehicle, refer to the Precautions section.
2. Disconnect the battery ground cable.
3. Remove the electrical connector.
4. Remove the bolt and the CMP sensor.
5. To install, reverse the removal procedure.

1. Before servicing the vehicle, refer to the Precautions section.
2. Disconnect the battery ground cable.
3. Remove the pin-type retainers and remove the accelerator cable snow shield.
4. Detach the spark plug wire retainer.
5. Detach the wiring harness from the intake manifold support.
6. Release the fuel charging wiring harness from the valve cover studs. Position the wiring harness away from the camshaft position sensor.
7. Disconnect the electrical connector.
8. Remove the screws and the CMP.
9. To install, reverse the removal procedure.
   NOTE Make sure that the fuel charging wiring harness is fully Need step by step diagrams to replace cam sensor - 0996b43f8020257a.jpg cover studs.
   

Testing

1. Check voltage between the camshaft position sensor terminaNeed step by step diagrams to replace cam sensor - 0996b43f80202e07.jpg/SPAN>
2. With engine running, voltage should be greater than 0.1 volt AC and vary with engine speed.
3. If voltage is not within specification, check for proper voltage at the VPWR terminal.
4. If VPWR voltNeed step by step diagrams to replace cam sensor - enlarge_icon.gifhan 10.5 volts, sensor mNeed step by step diagrams to replace cam sensor - enlarge_tooltip.gif>

1. Before servicing the vehicle, refer to the Precautions section.
   WARNING Use only a high-impedance multimeter, otherwise damage to the PCM and/or sensors can result.
   
2. With the key OFF , disconnect the CMP sensor harness connector.
3. Measure the resistance of the CMP sensor.
   
   3.0L Engine: 250-1000 ohms
   
4. If the resistance measured is outside the limits given, replace the CMP sensor.
