The detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control. You might also need the manufacturer and data systems that provide specifications and details relative to your specific model.
If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. What are the symptoms of code P0020? P0020 refers to the intake camshaft on bank 2 cylinder head of a multiple cylinder head engine. Most of the time, a similar reading means that the catalytic converter is not working as efficiently as it should be. You may have to replace it again…under warranty!
