There are quite a few different things that can cause the P0011. Tough to Start Motor– With the timing too far advanced, it is going to be difficult to start the motor, especially when it is warm.Service Engine Soon Light– Most of the time, you’ll be able to feel or see one of the above symptoms, but if you can’t, the service engine soon light will still come on and let you know that something is wrong.This is because the cam profile will not allow it run a performance power curve when you need more power. Lost Power– The engine will not be able to produce as much power.Decreased Gas Mileage– Now the engine can no longer adjust its cam timing on the fly, it will no longer be able to produce optimal combustion which equals poor economy.Poor Idle Quality– If the camshaft actuator fails while giving the engine aggressive valve timing, it’ll idle roughly.Here are some of the typical symptoms of P0011 in the Chevy Equinox: When the timing is too far advanced, it can really cause some issues with the motor. With P0011, the camshaft actuator is leaving the timing too far advanced, or there is a system performance issue (not working right). So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0011. They are hydraulic, which means that they use the vehicle’s engine oil to control lift. When the timing is too far advancedĬamshaft Position Actuators change the lift of the camshaft up to 25 degrees. This allows for a more efficient cam profile at any speed. The Chevy Equinox utilizes camshaft actuators to change the valve lift depending on the RPM of the motor. If your Equinox has the P0011 trouble code it will typically not pass the State emissions tests. This is great for both power and fuel economy. It allows the engine to act as though it has different camshaft profiles at different RPM’s. VVT changes the frequency and distribution of gases entering and exiting the combustion chamber. It has the same definition for the Chevy Equinox as it does on any other vehicle. This means that it has the same definition regardless of the make or model of the vehicle. P0011: Camshaft Position “A” – Timing Over Advanced -or- System Performance (Bank 1) The list of VVT vehicles is growing, and the Chevy Equinox can have VVT, and is prone to developing this code. It affects vehicles with variable valve timing (VVT).
