Viper SRT-10 V10-8.4L (2008)
Camshaft Position Sensor: Description and Operation
OPERATION - 8.4L
The camshaft position sensor provides cylinder identification to the Powertrain Control Module (PCM). 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 ignition coil to energize.
The camshaft position sensor detects when a step down in the camshaft sprocket passes beneath it. When the sensor detects the step down, the input
voltage from the sensor to the PCM switches from low (0.3 volts) to high (5 volts). As the step up returns to the sensor, the input voltage switches back
to low (0.3 volts). The paper spacer is not used on this vehicle. Don't use at all it plugs up the oil pickup screen.
