P0011 code help
Has anyone dealt with this code?
I keep getting this after a 15-20 track session but it only comes up after the session is over, usually as I’m pulling in to the pits. And it doesn’t happen every time either. It’s some cam timing code. The engine is stock btw. I seen a thread where someone had a wiring harness run on the accessories belt but after close inspection that’s not my issue.. |

Check this link and look at all of the scenarios that can cause your code.

Crank no start with DTC P0011 and / or P00C6 stored current or in history. The engine may sound like it is cranking fast and actual fuel rail pressure may be low. A compression test may show lower than expected readings and exhaust flow from the tailpipe may be noticeably lower while cranking as compared to a known good vehicle. The fuel rail pressure sensor may show 300 - 400 PSI and will slowly drop down into the 50 PSI range while cranking. The Camshaft Position Actuator Solenoid Valve may be sticking or binding causing the valve timing to be retarded. |

The engine oil level and the oil pressure are critical to the correct operation of the system. Verify the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic.
The engine oil condition has a major impact on the camshaft actuator system. Debris in the oil can interfere with the camshaft position actuator solenoid valve and the mechanical camshaft actuator operation. Inspect for dirty or degraded engine oil. If a crankshaft or camshaft position sensor DTC is set, the scan tool camshaft position actuator output control will be disabled. Ignition » On / Vehicle » In Service Mode Verify DTC P0010, P0016, P0335, P0336, P0340, P0341, P0345, P0346, P0365, P0366, P0390, P0391 is not set. If any of the DTCs are set Refer to: Diagnostic Trouble Code (DTC) List - Vehicle If none of the DTCs are set Verify the following conditions do not exist: Engine Oil — Contaminated / Dirty / Fill Level = Low Engine Oil Pressure — Low » Refer to: Oil Pressure Diagnosis and Testing If a condition exists Repair as necessary If no condition exists Engine idling. Perform the appropriate scan tool control function: Camshaft Position Actuator » From 0 to 20° and back to 0°.

Verify the scan tool parameter: Camshaft Position Variance = Less than 2° — During each of the commanded states If 2° or greater Refer to: Circuit/System Testing If less than 2° Verify the scan tool parameter: Camshaft Position Variance = Less than 2° Perform the action while monitoring the parameter: Wiggle the harness and connector: Q6 Camshaft Position Actuator Solenoid Valve Wiggle the harness and connector: K20 Engine Control Module If 2° or greater Repair as necessary » Wiring / Terminal(s) / Electrical Connector(s) If less than 2° Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data. Verify the DTC does not set. If the DTC sets Refer to: Circuit/System Testing If the DTC is not set All OK.
