Code definition P0011

Camshaft Position “A” – Timing or System Performance Excessive (Bank 1)

What does the code P0011 mean

P0011 is a generic OBD-II code which indicates that the engine control module (ECM) has determined that the intake camshaft in bank 1 is further extended than the ECM told it to be. This overtaking condition can occur during camshaft leading or lagging.

What causes the code P0011?

  • The camshaft and crankshaft sensors indicate that the camshaft is further forward than the ECM commands.
  • The camshaft is too far forward when the ECM has commanded the camshaft to be retracted to a lower camshaft position.
  • The camshaft oil control coil on the camshaft 1 of the bank may be stuck or have clogged wires.
  • The oil is too thick and the lines are clogged due to no oil flow in and out of the camshaft chamfers.
  • Camshaft phasers stuck in forward position.

What are the symptoms of the P0011 code?

  • The ECM will illuminate the check lamp of the engine and command the camshaft, if possible, to return to the normal starting position.
  • The engine may have difficulty starting if the cam is stuck in a too advanced or too late valve timing position.
  • The engine will have a reduced fuel mileage as the camshafts are not in their optimal positions to obtain the best fuel mileage.
  • Depending on the position of the camshaft, the engine may run rough, hesitate, or stall.
  • Engine exhaust emissions may exceed federal levels and fail the emissions test.

Note: Symptoms may vary depending on the timing position when the camshaft has stopped extending or retracting.

How can a mechanic diagnose the P0011 code?

  • Visual inspection for any problems with the electrical connector, wiring harness, or the camshaft oil adjusting valve for the bank 1 intake camshaft.
  • Check that the engine is filled with clean engine oil of the correct viscosity.
  • The technician scans and documents the received codes and looks at the data from the frozen frame to see when the code has been set.
  • He will then need to reset the codes to clear the OBD-II fault codes and retest the vehicle to see if the P0011 code returns.
  • If the code returns then the next step for the technician to do is to perform the manufacturer specific spot test for the P0011 code and repair as needed.

Note: Follow the manufacturer’s recommended spot test to narrow down the problem as each engine may be tested differently and possible internal engine damage could occur if the tests are not performed according to the correct procedure.

Common errors in diagnosing P0011 code?

Follow these simple tips to avoid mistakes:

  1. Always perform a visual inspection for common problems such as checking that all electrical connectors are connected.
  2. Check that the engine oil is full, clean, and has the correct viscosity.
  3. Check, document and clear fault codes. Check that the code has reappeared before performing further tests.
  4. The manufacturer’s testing procedures must be performed step by step, without skipping any steps, to avoid misdiagnosis and replacement of good components.
  5. Do not replace any sensor or component unless testing indicates a problem.

How serious is the P0011 code?

  • The engine may run erratically and may stagger, swing, run erratically, or have difficulty starting.
  • Depending on the incorrect position of the camshaft, excessive fuel consumption, carbon deposits on the engine components and various ailments while driving can occur.
  • Driving the car for an extended period of time with camshafts not retracting or retracting may cause other problems with the timing system or the engine depending on the cause of the failure.

What repairs can remove the P0011 code?

  1. Reset fault codes and perform road test.
  2. Change the oil and filter with an oil viscosity according to the engine specifications.
  3. Repair or replace the wiring of the camshaft oil control valve for the bank 1 intake camshaft.
  4. Replace the camshaft oil regulating valve for intake camshaft position 1
  5. Checking the alignment of the timing chain to avoid problems with the timing

Additional notes to be noted for the P0011 code

The passage of the engine oil through the camshafts and the oil control valves is specially sized and only oil of the viscosity recommended by the manufacturer should be used. If an oil that is too thick or thin is used, the timing chamfers may not change the camshaft lead as specified by the manufacturer and may cause premature failure of the camshaft and associated engine components due to a lack of proper lubrication.
