1. Understanding the EOBD/OBDII P0022 Error Code

The P0022 error code signifies “A” Camshaft Position – Timing Over-Retarded (Bank 2). This code indicates that the camshaft timing in Bank 2 is more retarded than the Engine Control Module (ECM) or Powertrain Control Module (PCM) expects. Variable Valve Timing (VVT) and Variable Camshaft Timing (VCT) systems are crucial for optimizing engine performance and fuel efficiency. When the camshaft timing is excessively delayed, it triggers the P0022 code, signaling a potential issue within the engine’s timing mechanisms. This problem can stem from several factors, requiring a systematic approach to diagnose and resolve effectively.

What Does “Timing Over-Retarded” Mean?

“Timing Over-Retarded” implies that the camshaft is rotating slower than the optimal setting specified by the vehicle’s computer. The camshaft’s position relative to the crankshaft is crucial for proper valve operation. When the camshaft timing is retarded, the intake and exhaust valves open later than intended, potentially leading to decreased engine performance and fuel efficiency. The ECM continuously monitors the camshaft position, comparing it to the crankshaft position to ensure accurate timing. If the ECM detects that the camshaft is significantly behind the desired position, it sets the P0022 code. Understanding the concept of retarded timing is essential for diagnosing and correcting the underlying mechanical or electrical issues.

Bank 2 Definition

Bank 2 refers to the side of the engine opposite the number 1 cylinder. In V-shaped or horizontally opposed engines, cylinders are arranged in two banks. Identifying Bank 2 is crucial for pinpointing the location of the problem, as the P0022 code specifically relates to the camshaft timing on this bank. For example, in a V6 engine, one side is Bank 1 and the other is Bank 2. Technicians need to consult the vehicle’s service manual to accurately identify which side is Bank 2, ensuring the diagnostic and repair efforts are focused on the correct area. Correctly identifying Bank 2 saves time and reduces the risk of misdiagnosis.
