SENSOR-CAMSHAFT POSITION
DESCRIPTION
The camshaft position sensor is mounted on the right cylinder head cover (1). The hall effect sensor supplies a signal to the Electronic Control Module (ECM). The ECM uses the signals sent by the CMP and the crankshaft sensor to determine injection timing.
OPERATION
The signal circuit of the camshaft sensor has a voltage of approximately 5V. If the segment machined into the intake camshaft sprocket is positioned opposite the camshaft sensor, the camshaft signal is approximately 0V. This 0V to 5V signal is used by the engine control module (ECM) for detecting ignition TDC of cylinder 1 as the engine rotates. If no signal is supplied by the camshaft position sensor, the vehicle will not start.
REMOVAL
1. Disconnect negative battery cable. (Refer to 8 - ELECTRICAL/BATTERY SYSTEM/BATTERY - REMOVAL)
2. Remove engine cover. (Refer to 9 - ENGINE - REMOVAL)
3. Disconnect camshaft position sensor electrical connector.
4. Remove retaining bolt and remove sensor.
INSTALLATION
1. Install camshaft position sensor and tighten bolt to 8 N·m (71 in.lbs.).
2. Reconnect electrical connector.
3. Install engine cover.
4. Reconnect negative battery cable.
