5. (F855) 5 VOLT SUPPLY CIRCUIT SHORTED TO THE (K441) CMP 1/2 SIGNAL CIRCUIT Measure the resistance between the (F855) 5 Volt Supply circuit and Is the resistance above 100 ohms? Yes >> Go to 6 No >> Repair the (F855) 5 Volt Supply circuit for a short to the (K441) CMP 1/2 Signal circuit. Perform the PCM Verification Test Ver. 1 (Refer to 9 - 6. CAMSHAFT 1/1 POSITION SENSOR IRREGULAR SIGNAL Connect the Camshaft 1/2 Position Sensor connector. Using a lab scope and the Miller special tool #6801, backprobe the Ignition on, engine not running. Wiggle the related wire harness and lightly tap on the Camshaft 1/1 Start the engine. Monitor the Camshaft 1/1 Position Sensor signal on the lab scope Were any Camshaft 1/1 Position Sensor signals irregular or Yes >> Go to 16 No >> Go to 17 7. (F855) 5 VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE Turn the ignition off. Disconnect the Powertrain Control Module (PCM) connector. Turn the ignition on. Measure the voltage of the (F855) 5 Volt Supply circuit in the Camshaft Is there any voltage present? Yes >> Repair the (F855) 5 Volt Supply circuit for a short to volt- age. Perform the PCM Verification Test Ver. 1 (Refer to 9 - No >> Go to 8 PM ENGINE ELECTRICAL DIAGNOSTICS - GPEC 9 - 347 |
