PT Cruiser L4-2.4L Turbo VIN G (2004)
Target Magnet - Typical
The PCM sends approximately 5 volts to the Hall-effect sensor. This voltage is required to operate the Hall-effect chip and the electronics inside the
sensor. The input to the PCM occurs on a 5 volt output reference circuit. A ground for the sensor is provided through the sensor return circuit. The PCM
identifies camshaft position by registering the change from 5 to 0 volts, as signaled from the Camshaft Position sensor.
Target Magnet Polarity - NGC
On 2.0/2.4L engines a target magnet attaches to the rear of the camshaft and indexes to the correct position. The target magnet has fourteen different
poles arranged in an asymmetrical pattern. As the target magnet rotates, the camshaft position sensor senses the change in polarity.
The PCM determines fuel injection synchronization and cylinder identification from inputs provided by the camshaft position sensor and crankshaft
position sensor. From the two inputs, the PCM determines crankshaft position.
The sensor input switches from high (5 volts) to low (0.30 volts) as the target magnet rotates. When the north pole of the target magnet passes under the
sensor, the output switches high. The sensor output switches low when the south pole of the target magnet passes underneath.
