Camshaft Position Sensor (626 2.5L)

Disconnect Camshaft Position (CMP) sensor harness connector. CMP sensor is located next to right timing pulley. Using ohmmeter, measure resistance between CMP sensor harness connector terminals "A" and "B". Resistance should be approximately 550 ohms. If resistance reading is not as specified, replace CMP sensor. If CMP sensor is okay, disconnect PCM harness connector and check for open or short circuit in wiring harness between following:

• CMP sensor terminal and PCM harness connector terminal No. 8 (Blue wire).
• CMP sensor terminal and PCM harness connector terminal No. 85 (Pink wire).

Repair or replace wiring harness as necessary.
