What Does Code P0020 Mean? DTC P0020 signifies a general circuit malfunction within the Camshaft Position (CMP) Actuator circuit for Engine Bank 2. Bank 2 refers to the cylinder bank that does not contain cylinder #1 (typically the passenger side on transverse engines, or the driver’s side on longitudinally mounted V6/V8 engines in North America). […]

What Does Code P0021 Mean? The diagnostic trouble code P0021 indicates an issue with the Variable Valve Timing (VVT) or Camshaft Phasing system specifically on the intake camshaft of Bank 2. The Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), monitors the actual position of the intake camshaft relative to […]

What Does Code P0022 Mean? The OBD-II diagnostic trouble code P0022 stands for “Camshaft Position – Timing Over-Retarded (Bank 2)”. This code indicates that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected that the intake camshaft on Bank 2 is significantly more retarded than commanded or expected for […]

What Does Code P0023 Mean? DTC P0023 indicates an electrical circuit malfunction detected by the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), within the Camshaft Position Actuator ‘B’ circuit on Bank 2. In most variable valve timing (VVT) systems, ‘A’ typically refers to the intake camshaft and ‘B’ refers to […]

What Does Code P0024 Mean? DTC P0024 signifies that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an inconsistency in the commanded versus actual position of the “B” camshaft on Bank 2. Specifically, it indicates that the exhaust camshaft (commonly referred to as “B” camshaft in VVT systems) […]

What Does Code P0025 Mean? DTC P0025 signifies “B Camshaft Position – Timing Over-Retarded (Bank 2).” In the context of Variable Valve Timing (VVT) or Variable Camshaft Timing (VCT) systems, the letter ‘B’ specifically designates the exhaust camshaft. “Bank 2” refers to the cylinder bank that does not contain cylinder number one; for most V-type […]

What Does Code P0026 Mean? DTC P0026 indicates an issue with the electrical circuit or the performance range of the Intake Valve Control Solenoid on Bank 1. This code specifically points to a malfunction within the Variable Valve Timing (VVT) or Variable Valve Lift (VVL) system that controls the intake valves on the engine bank […]

What Does Code P0027 Mean? DTC P0027 indicates an issue with the exhaust camshaft position actuator solenoid circuit, or the performance of the solenoid itself, for Bank 1 of the engine. Bank 1 refers to the side of the engine containing cylinder number one. This code specifically points to the variable valve timing (VVT) or […]

What Does Code P0028 Mean? DTC P0028 signifies an detected “Intake Valve Control Solenoid Circuit Range/Performance” issue on Bank 2. This code specifically points to a malfunction within the Variable Valve Timing (VVT) or Variable Valve Lift (VVL) system’s intake camshaft oil control valve (OCV), also commonly referred to as the VVT solenoid, for the […]

What Does Code P0029 Mean? The diagnostic trouble code P0029 indicates an issue with the Exhaust Valve Control Solenoid Circuit on Bank 2 operating outside its specified Range/Performance parameters. Bank 2 refers to the cylinder bank that does not contain cylinder #1. This code specifically targets the electrical circuit and/or the functional performance of the […]
