Camshaft Position Sensor (3.0L)
The Camshaft Position (CMP) sensor is located to the left of the cylinder No. 2, 4 and 6 timing belt cover/exhaust camshaft sprocket. CMP sensor is a Hall Effect sensor used to determine the position of the bank 2 exhaust camshaft. CMP sensor detects a single tooth on the reluctor wheel of the camshaft, which denotes 90 degrees before Top Dead Center (TDC) of cylinder No. 1 compression stroke. CMP sensor is used by PCM to determine when cylinder No. 1 is approaching TDC to synchronize the correct firing order. CMP sensor is also used to enable sequential or independent fuel injection and to enable spark knock control.
