Camshaft Position Sensor: Description and Operation
Fig 8 Camshaft Position Sensor
CAMSHAFT POSITION SENSOR
The camshaft position sensor provides cylinder identification to the Powertrain Control Module (PCM) (Fig. 8). The sensor generates pulses. The
PCM determines crankshaft position from the camshaft position sensor and crankshaft position sensor inputs. The PCM uses the input to
determine fuel injection synchronization and to determine which electric ignition coil to energize.
Fig 9 Camshaft Sprocket
The camshaft position sensor detects when a step in the camshaft sprocket passes beneath it (Fig. 9). When the sensor detects the step, the input
voltage from the sensor to the PCM switches from low (0.3 volts) to high (5 volts). As the step returns away from the sensor, the input voltage
switches back to low (0.3 volts).
