CMP And CKP Sensor Circuit Wiring Diagram (2003-2007 2.4L Honda Accord)

APPLIES TO: This CMP and CKP sensor circuit wiring diagram applies to the following vehicles:

This CMP and CKP sensor circuit wiring diagram includes the following circuits:

CMP Sensor A.
- Mounted on the intake camshaft and used by the VTC (Variable Timing Control) system to monitor camshaft position and adjust valve timing for engine performance and efficiency.
CMP Sensor B.
- Mounted on the exhaust camshaft and used together with the CKP sensor to identify cylinder #1's position and synchronize fuel injection and ignition timing.
CKP Sensor.
- Monitors crankshaft position and speed, providing the PCM with the base timing signal for engine operation.

CMP AND CKP SENSOR TESTS: The CMP (A and B) and CKP sensors can be tested with a multimeter and I'll show you how here:
