Wiring Diagram:

CIRCUIT DESCRIPTION
The sensor is mounted on the sensor case (distributorless ignition case) on the camshaft left side. The signal rotor is press-fitted onto the camshaft. As the sensor has a built-in hall element (element which generates voltage from changes in the magnetic flux) and a waveform forming circuit, it converts changes in the magnetic flux caused by rotation of the signal rotor into electric pulse signals. Using this signal and the signal from the CKP sensor, ECM (PCM) identifies the cylinder whose piston is in the compression stroke.

Detecting Condition / Possible Cause:

Reference
Connect oscilloscope between terminals C22-2 and C21-1 (ground) of ECM connector connected to ECM and check CMP sensor signal.

DTC CONFIRMATION PROCEDURE
1. Clear DTC.
2. Start engine and keep it at idle for 1 min.
3. Select "DTC" mode on scan tool and check DTC.
