P0011 Code: “A” Camshaft Timing over Advanced (Bank 1)

This generic trouble code is generated on any vehicles that are equipped with an OBD-II system. This code is related to the variable camshaft timing components..

Definition of P0011 code

It is OBD-II generated DTC trouble code that explains about Camshaft Position “A” – Timing Over-Advanced or System Performance (Bank 1)

What does this P0011 code mean?

The P0011 is OBD-II generated generic code that specifies the engine control module determines that the bank 1 intake has detected more advanced features than ECM commanded it. This condition is known as over advanced condition that causes because of the retarding of camshaft timing.

This generic trouble code is generated on any vehicles that are equipped with an OBD-II system. This code is related to the variable camshaft timing components.

Variable valve timings and variable camshaft timing are the advanced technologies that help the engine to perform differently under certain situations. These technologies can result in more fuel efficiency or the need for more power.

When there is a problem in these systems several error codes generated, P0011 refers to the “A” camshaft in bank one. This error code signifies that the camshaft timing is more than the threshold and this condition is known as over advanced.

Possible causes of P0011 error codes

  • The camshaft and crankshaft sensors indicate that the camshaft is more advance than the ECM commanded it to be advance
  • Damaged camshaft timing components
  • Clogged passes in the oil control solenoid to the bank 1 camshaft
  • Due to lack of oil flow passages to become clogged
  • The camshaft get stuck in advance position
  • Faults in circuits
  • Faults in camshaft sensors
  • Problems in PCM

Symptoms of P0011 error code

You can notice the following symptoms when your vehicle is diagnosed with P0011 error code:

  • Check Engine Light is On
  • Engine stalls while starting
  • Poor idling time of vehicle
  • Difficulty while starting the engine
  • Excessive fuel efficiency
  • Engine misfire often
  • Failure in emission test
  • Wired noise from the engine

The severity of the P0011 error code

There may be many bad effects on your vehicle if it is detected with the P0011 error code. The functioning of the engine may get disturbed as in the engine stall while starting, hesitate, run rough, or have a hard starting condition. There will be excessive fuel consumption in the engine, carbon fouling in the engine. You can notice a problem in driveability and driving complaints related to a failed camshaft position.

A driving vehicle with failed camshafts can cause severe problems, so it is advisable to take your vehicle to the experts.

How to diagnose and troubleshoot the P0011 error code?

The error code P0011 is difficult to diagnose and involves various steps to find the root cause of the problem. Sometimes, you need to remove and check the condition of the camshaft position compartments.

Start by clearing the error codes- check engine lights illuminates for unknown reasons and clear the cause of the error code and resolve the issue. Note down the error codes as they may be the root cause of the problem.

Check the amount of engine oil- the condition of engine oil and the viscosity of the oil is a common cause of the valve timing problem.

You need to change the engine oil and ensure that it is replaced with good quality oil. Also, check the quantity of the oil and top up if necessary.

Check sensor and actuator wiring- check if there is a break in the wirings of the actuator and the protective layer is not damaged.

Check the wirings to the sensors and clarify that they are tightly fitted and they’re clean and do not have any faults.

Remove and clean crankshaft and crankshaft sensors-If the ECU has detected the error codes P0011, then it is clear that there are faults in crankshaft or crankshaft sensors.

Remove the sensors and clean them with solvent cleaner and take the vehicle for a short drive. If you had tried all the steps but you are not able to solve the problem then you need to investigate further. The system of every vehicle is different, so take out the camshaft position actuator to check if it is clogged.

If you are still facing problems in your vehicle, follow the specific test for P0011. Instructions are mentioned in your manual. These steps will help you to detect the root cause of the problem.

These steps depend upon the manufacturer, so make sure that you are following the correct instruction for your vehicle.
