Camshaft timing refers to the precise alignment of the camshaft(s) in relation to the engine’s crankshaft. When the powertrain control module (PCM) detects an issue with the bank 2 camshaft timing, it triggers the diagnostic trouble code (DTC) P0022. This article explains the P0022 code Toyota meaning, causes, symptoms, and fixing cost.

P0022 Code Definition

The P0022 code stands for “Camshaft Position A – Timing Over-Retarded (Bank 2).”

What does the P0022 Code Mean?

The P0022 code indicates that your PCM has detected that the intake camshaft timing for bank 2 is over retarded than what the PCM has set it to be.

Proper camshaft timing is crucial for the engine to operate efficiently and smoothly. If the camshaft timing is off, it can cause the valves to open and close at the wrong time, which can result in poor engine performance, reduced fuel efficiency, and even engine damage.

The over-retarded timing situation may occur during the advancing or retarding phase of the camshaft timing.

It’s important to have the camshaft timing checked and adjusted regularly as part of routine engine maintenance. Over time, the timing chain or belt can wear or stretch, which can cause the camshaft timing to become out of sync with the crankshaft. This can be corrected by adjusting the timing or replacing the timing chain or belt. If the camshaft timing is off due to a faulty camshaft position sensor or VVT solenoid, it’s also important to have those components replaced.

Symptoms of P0022 Code

The P0022 code is a generic powertrain code that relates to the camshaft position sensor. It indicates that there is a problem with the camshaft position timing, which may result in poor engine performance and other issues. Here are some of the symptoms that you may experience with the P0022 code:
