Why does my Mazda CX-9 have bad timing?
When the timing is over retarded, it can really cause some issues with the motor. Here are some of the typical symptoms of P0012 in the Mazda CX-9: Poor Idle Quality – If the camshaft actuator fails it can be tough for the engine to find the right idle speed or idle smoothly.
How does the camshaft work on a Mazda CX-9?
The Mazda CX-9 utilizes camshaft actuators to change the valve lift depending on the RPM of the motor. This allows for a more efficient cam profile at any speed. With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees.
What causes the camshaft timing control to malfunction?
The oil needs to be the proper viscosity for the camshaft timing control to work as designed. If you use too thick of oil it can cause this system to malfunction and cause codes and running issues with the engine. Incorrect oil can cause this code and may cause multiple codes along with it.

What makes a Mazda CX-7 die while driving?
Some include the timing chain becoming stretched, the turbo goes out, the car loses power while driving, there is a ticking noise, the timing chain breaks, the check engine light comes on, and the car dies while driving. The biggest problem revolves around the timing chain becoming stretched.

What to do if you have a camshaft timing problem?
Changing the oil and filter to the proper oil viscosity for the engine’s specifications. Repairing or replacing the wiring or connection to the camshaft oil control solenoid. Replacing the camshaft oil control valve for bank 1 intake camshaft. Check the timing chain alignment for jumped timing problems and repair as needed.
Why is my camshaft not retarding in my car?
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 a prolonged time with the camshafts not retarding may cause other problems to the valve train or engine depending on the cause of the failure.
