Inside your car’s engine, you’ll find one or more camshafts. Each camshaft has egg-shaped lobes that operate a series of valves to let air in and out of the engine. Most modern vehicles are equipped with a technology, called variable valve timing, that adjusts the camshaft position and, in turn, alters the timing of the valves.  If your vehicle’s primary computer detects too much delay in camshaft timing, you will likely have to deal with the P0022 code.

What Does the P0022 Code Mean?

Diagnostic trouble code (DTC) P022 code stands for “Intake “A” Camshaft Position – Timing Over-Retarded (Bank 2).” It indicates that your car’s primary computer, which is often referred to as the powertrain control module (PCM), perceives an over-retarded or over delayed timing condition in Bank 2 of the intake camshaft.

Code P0022 is logged when the PCM perceives an over-retarded or over delayed timing condition in Bank 2 of the intake camshaft.

The crankshaft and camshaft position sensors relay information to the PCM. The module uses the data to determine whether the engine is timed properly by comparing the input from both sensors. As was mentioned, in newer vehicles, a variable valve timing system orchestrates the opening and closing of the intake and exhaust valves for better fuel efficiency and/or performance.

The PCM triggers the code P0022 when it detects that the camshaft is not in the proper position relative to the crankshaft.

An in-depth knowledge about camshaft angle and variable valve timing can help you come up with a proper solution for P0022 if you’re planning a DIY fix.

Note: The definition of code P0022 may be identified differently depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

How to Diagnose the P0022 Code

Identifying the underlying cause of the P0022 code can be difficult, especially if you’re not confident with your automotive knowledge. In most cases, it would be best to bring your vehicle to an auto repair shop and seek the help of a professional for an accurate diagnosis.

Here is a video that can help give you a better idea of how this trouble code is might be diagnosed:

How to Fix the P0022 Code

The P0022 code is a generic trouble code that may apply to various makes and models. While vehicles from different manufacturers may share common symptoms, the steps for diagnosis and repair for a P0022 Ford code may differ from a P0022 Nissan code.

If you’re an advanced DIYer who’d like to fix this code on your own, it will be helpful to get factory vehicle repair information from an online subscription service. Research how to fix the P0022 code when it logs to a vehicle with your year, make, and model.
