Fix P000C: Mechanic’s solutions that WORKED

The P000C: Camshaft Position Slow Response (Bank 2) is set when the ECM detects a slower than expected response from the camshaft position actuator in Bank 2. This could be due to issues affecting the variable valve timing (VVT) system, such as oil flow problems or mechanical faults in the camshaft actuator or related components. This slow response can affect engine timing and performance.

P000C quick overview

Meaning	P000C: Camshaft Position Slow Response (Bank 2)
Is it serious?	This code can be serious as it may lead to poor engine performance, increased emissions, and potentially more significant engine issues if left unaddressed.
Possible causes	– Insufficient or dirty engine oil – Malfunctioning camshaft position actuator – Clogged oil passages – Worn timing components – Faulty camshaft position sensor – Issues with the engine control module (ECM)
How to diagnose?	Check Engine Oil: Ensure the oil level is adequate and the oil is clean. Inspect Camshaft Actuator: Evaluate the camshaft position actuator for defects or failure. Clear Oil Passages: Confirm that the oil passages are free of obstructions. Examine Timing Components: Look for wear or damage in timing belts or chains. Test Camshaft Position Sensor: Check the camshaft position sensor for proper function. Scan for ECU Codes: Use a diagnostic tool to read and clear any related ECU codes.

How to fix P000C – learn from mechanics

I looked into P000C service cases at iatn.com website where in the private forums the mechanics seek advice from other mechanics. I looked up a bunch of cases to help you decide how to fix your issue and see what would a real mechanic do to solve it.

Case #1: Dodge

Vehicle Information: 2012 Dodge Durango SXT 3.6L

Issue + Repair History:

• Came in with overheating due to a head gasket issue.
• Replaced head gaskets, then replaced with a used engine due to thread issues in the block.
• After engine replacement, cam and crank codes appeared.
• Original engine had prior timing cover removal.

Other OBD2 Codes + Test Results:

• P0019
• P000A: Bank 1, cam 1 position slow response
• P000C: Bank 2, cam 1 position slow response

Suggestions to Fix Issue:

• Perform a cam and crank relearn.
• Check and clean intake and exhaust phasers.
• Verify oil pressure, especially on engines with unknown history.
• Scope cam and crank signals for comparison with known good patterns.
• Check for loose or dropped oil galley plugs, known issue with a TSB.
• Ensure all timing marks on cam phasers are correctly aligned.

Final Fix:

• Performed a cam and crank relearn and cleaned intake and exhaust phasers using a scanner. After these procedures, the vehicle ran well and codes did not return.

Case #2: Subaru

Vehicle Information: 2011 Subaru Forester XT Touring 2.5L

Issue + Repair History:

• Persistent P0011 code indicating “Intake camshaft position timing over-advanced or system performance” on bank 1.
• Rough idle and occasional misfire on cylinders #1 and #3.
• More duty cycle on bank 1 but lower advance compared to bank 2.
• Regular maintenance and oil changes were performed on the vehicle.
• Left side oil control solenoid valve replaced without resolving the issue.

Other OBD2 Codes + Test Results:

• P0011: Intake camshaft position timing over-advanced or system performance, Bank 1.

Suggestions to Fix Issue:

• Refer to TSB 02-132-12R for AVCS-related DTCs.
• Consider a reflash for misfire DTCs.
• Swap the oil control valve to see if the problem switches sides.
• Perform an engine oil flush.
• Check for reflash applicability with Subaru.
• Inspect ground splice in the harness near the passenger strut tower, especially for turbo models.
• Ensure using 5w30 synthetic oil and change every 3k miles.
• Check lash between cam lobes and lifters/shims.
• Perform a leak-down test.

Final Fix:

• Misdiagnosed engine orientation led to the wrong placement of the new oil control solenoid valve. The issue was resolved by installing the new valve on the correct side (right side) due to engine rotation in newer Foresters.

Case #3: Ford

Vehicle Information: 2013 Ford F-150 XLT 5.0L V8

Issue + Repair History:

• Check Engine Light on with code P000C: “Camshaft Position Slow Response – Bank 2.”
• Vehicle experienced occasional rough idling and loss of power during acceleration.
• Regular maintenance, including oil changes, had been performed.
• Replaced Bank 2’s camshaft position sensor without resolving the issue.

Other OBD2 Codes + Test Results:

• P000C: Camshaft Position Slow Response – Bank 2.

Suggestions to Fix Issue:

• Perform an oil change with recommended viscosity oil, as improper oil viscosity can affect camshaft timing.
• Inspect the wiring and connectors related to the camshaft position sensor on Bank 2 for damage or corrosion.
• Check for oil sludge build-up, which could affect the camshaft’s operation.
• Verify the timing chain tension and condition, as a stretched or worn chain could cause timing issues.
• Reset the camshaft adaptation values using a scan tool.

Final Fix:

• Found that the timing chain on Bank 2 was slightly stretched. Replaced the timing chain, reset camshaft adaptation values, and the vehicle returned to normal operation. Code P000C did not reappear after several test drives.

Case #4: Audi

Vehicle Information: 2014 Audi A6 Quattro 3.0L V6

Issue + Repair History:

• Persistent P000C code indicating slow camshaft position response for Bank 2.
• Minor performance issues noted, especially during cold starts.
• Oil changes were performed regularly with the correct grade of oil.
• Attempted clearing of codes and ECU reset did not resolve the issue.

Other OBD2 Codes + Test Results:

• P000C: Camshaft Position Slow Response – Bank 2.

Suggestions to Fix Issue:

• Inspect the camshaft position actuator for Bank 1 for proper operation and oil flow.
• Check for any software updates from Audi that might address this issue.
• Conduct a thorough inspection of the Variable Valve Timing (VVT) system, including solenoids and oil passages.
• Test the oil pressure to ensure it meets the specifications for the vehicle’s engine.
• Consider the possibility of mechanical wear in the camshaft area, necessitating a more in-depth engine inspection.

Final Fix:

• The camshaft position actuator for Bank 2 was found to be clogged with debris. Cleaned the actuator and the associated oil passages. The P000C code cleared and the engine’s performance improved significantly.

Case #5: Chevrolet
