How to Test Camshaft Position Sensor on Ford Windstar?

The details to Test Camshaft Position Sensor are as follows :-----


Description & Operation

The CMP sensor, also known as the Cylinder Identification (CID) sensor, provides camshaft position information, called the CMP or CID signal, which is used by the Powertrain Control Module (PCM) for fuel and ignition system synchronization.
The sensor is located at the front of the engine in the bore formerly occupied by the distributor.

  1. Check voltage between the camshaft position sensor terminals PWR GND and CID.
  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 voltage is greater than 10.5 volts, sensor may be faulty.

This will help.
