    • Connected a scan tool and found code P0015 – A Camshaft Position – Timing Over-Advanced Or System Performance (Bank 1). Used the scan tool to monitor live data and observed the camshaft position (CMP) sensor displayed an intermittent signal. Continued to monitor the live data, increased the engine speed to 2,000 RPM and found the CMP sensor remained erratic. Visually inspected the CMP sensor wiring harness and connectors, but found no evidence of any damage. Backprobed the CMP sensor signal wire, attached a lab scope and started the engine. While the CMP sensor signal was monitored on the lab scope, gradually increased the engine speed and observed the CMP sensor signal became erratic and dropped out. Continued to monitor the CMP sensor signal on the lab scope, wiggled the CMP sensor harness and observed no change in the signal. Disconnected the CMP sensor harness connector, inspected the terminals and found no faults were present. Key off, used a multi-meter to check for the presence of a short in the CMP sensor signal circuit and found no short was present. The results of these tests verified the CMP sensor was faulty. Also this vehicle has low engine oil. Sludge build up inside engine will cause other internal problems. It will also need an engine flush with solvent to clean sludge build up. [PLEASE NOTE THAT THIS VEHICLE MAY HAVE POSSIBLE INTERNAL PROBLEMS DUE TO VERY LOW ENGINE OIL]
    • REMOVE ALL NECESSARY COMPONENTS. REMOVE AND REPLACE CAMSHAFT POSITION SENSOR. ASSEMBLE TOGETHER AND RESET ECU.
    • FLUSH ENGINE OIL AND USE ENGINE OIL TREATMENT. RUN VEHICLE TO GIVE TIME FOR CHEMICAL SOLUTION TO SOLVATE SLUDGE BUILD UP AND DRAW AS MUCH OF IT BACK INTO THE OIL. DRAIN ENGINE OIL AND RUN SAME PROCESS MULTIPLE TIMES.
