P0011 INTAKE CAMSHAFT POSITION TIMING OVER ADVANCED BANK 1 CODE

If the oil supply to the actuator becomes blocked then this can trigger the error code P0011. Oil pressure can be affected for numerous reasons such as insufficient amount of oil in the engine, using the wrong viscosity oil, old and degraded oil, problems with the oil pump, damaged or worn oil filter or a worn engine. If the oil pressure is not sufficient, this can affect the operation of the camshaft position actuator. Here is an explanation of the main causes of OBD 2 code P0011. Other error codes may also be present such as P0010 or P0012, and P0014 or P0016. There can be many reasons for the ECU to register a P0011 code. It is most commonly caused by insufficient engine oil pressure in the camshaft position actuator. P0011 is associated specifically with the “A” camshaft and is specific to bank 1 (cylinder 1). What Causes Engine Error Code P0011Įngine trouble code P0011 refers to the timing of the camshaft, and is usually triggered when the timing falls outside of specific parameters, and is in an over-advanced state. If the ECU detects a camshaft phase angle that is outside of the expected range, this can trigger the engine code P0011. The engine control unit monitors the camshaft phase angle and can adjust the oil pressure according to the ECU’s instructions. The EGR (exhaust gases recirculation valve) can also be used to route exhaust gases back into the fuel/air mixture, reducing the fuel required for combustion.

Variable valve timing has the potential to reduce emissions and improve fuel efficiency. The ECU uses the camshaft position actuator for advancing or retarding camshaft timing depending on a myriad of factors and inputs from other engine sensors that continuously monitor the current state of the engine. Slowing the camshaft timing results in better high RPM torque, whereas advancing the camshaft’s timing allows the engine to create more power at lower RPMs. What Are The Benefits Of Variable Valve Timing? It doesn’t control the length of time a valve is open, but can alter the timing of the opening of the valve. This solenoid can regulate oil pressure by acting like a hydraulic actuator, controlling the flow of oil to camshaft actuator. This is a simpler system that makes use of a special solenoid called a camshaft position actuator. They can all have different shapes, and they can be used at different RPMs.Īnother type of system is called Cam-Phasing VVT. There can be multiple sets or cams in this VVT system. Honda was the pioneer of a type of variable valve timing called Cam-Changing VVT, with their VTEC (Valve Timing Electronic Control) system.

It may be advantageous to open the intake valves sooner and close them later at higher revs. However, they can be adjusted to improve performance under certain conditions. The valves can not open and close at the same time. Many modern vehicles have engines that have variable valve timing (VVT).

It is where the engine management software has detected that the camshaft rotation is not as advanced as it should be. This OBD2 code refers to bank 1 camshaft timing.

The engine error code P0011 means that there is a problem with the variable valve timing in the engine.
