Bad Intake Camshaft Position Actuator Solenoid– The actuator solenoid itself can go bad over time.Engine Oil– If the engine oil is dirty or low, it may cause the actuator to function improperly.Here’s more on that from this site: Timing Chain Jumped Symptoms and Diagnosis Engine Timing– If the camshaft(s) are no longer synced to the crank properly (such as if the timing chain jumped a tooth), it can cause the engine timing to be off enough to throw the P0012 even though it’s not the Actuator’s fault.There are quite a few different things that can cause the P0012. Tough to Start Motor– With the timing over retarded, 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 Equinox’s 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 it can be tough for the engine to find the right idle speed or idle smoothly.Here are some of the typical symptoms of P0012 in the Chevy Equinox: When the timing is over retarded, it can really cause some issues with the motor. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0012. They are hydraulic, which means that they use the vehicle’s engine oil to control lift. With P0012, the camshaft actuator is leaving the timing retarded.Ĭamshaft 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.
This ability to alter valve timing 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. P0012 is generic, which means that it has the same definition for the Equinox as it does on any other vehicle. The list of VVT vehicles is growing, and the Chevy Equinox can have VVT, and is known to develop this code.
It affects vehicles with variable valve timing (VVT). How long before some one is seriously injured or killed?.P0012 is a common trouble code. It literally stopped in mid acceleration. This car just cut off in the dead of winter coming off the highway. I am a single mother of 4 I bought this truck brand new to safely transport my children here, there and everywhere. I've heard from numerous goggle searches that gm is aware of the issues with this motor/vehicle and has done nothing to remedy the problem.
My truck has less than 100,000 miles on it. Now I'm being told they think it may be electrical. I have not driven my car (aside from the 3 miles) in nearly 2 months. 60 later, my truck drove for approximately 3 miles where it died on the side of the road. I've had the vvt celanide replaced as well as the crank and cam shaft sensors the vvt gears and an oil pump rebuild. 60 I was advised that the timing change and guides needed to be replaced. Initially the rear main seal was leaking or broken all the oil drained from the vehicle.
