Common mistakes when diagnosing the P0011 code?
Follow these simple guidelines to prevent mistakes:
Always do a visual inspection for common problems like checking to see if all electrical connectors are connected.
Check engine oil to see if it is full, clean, and of the correct viscosity.
Check, document and clear failure codes. Test to verify the code coming back before any further tests are done.
The manufacturer pinpoint test procedures should be followed step-by-step without skipping any steps to prevent a misdiagnosis and replacing of good components.
Do not replace any sensors or components unless tests indicate a problem.
How serious is the P0011 code?
The engine may run erratic and stall, hesitate, run rough, or have a hard starting condition.
The engine may have excessive fuel consumption, carbon fouling of engine components, and various drive complaints depending on the camshaft failed position.
Driving the vehicle for prolonged time with the camshafts not advancing or retarding may cause other problems to the valve train or engine depending on the cause of the failure.
What repairs can fix the P0011 code?
Resetting the fault codes and performing a road test
Changing the oil and filter to the proper oil viscosity for the engine specifications
Repairing or replacing the wiring to the camshaft oil control valve for bank 1 intake camshaft
Replacing the camshaft oil control valve for bank 1 intake camshaft
Checking the timing chain alignment for jumped timing problems
Additional comments for consideration regarding the P0011 code
The engine oil passages through the camshafts and oil control valves are a specific size and only the manufacturer's recommended oil viscosity should be used. If too thick or thin oil is used, the camshaft timing phasers may not change the camshaft timing advance as the manufacturer’s designed them to and may cause premature failure of camshaft and related engine components from lack of proper lubrication.
