Breeze L4-2.4L VIN X (2000)
Target Magnet Polarity
A target magnet attaches to the rear of the camshaft and indexes to the correct position. The target magnet has four 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.
