The P0021 trouble code, officially known as “A Camshaft Position Timing Over-Advanced (Bank 2),” is a diagnostic code triggered by the vehicle’s powertrain control module (PCM) when the intake camshaft in Bank 2 is more advanced than expected. This issue often stems from problems in the variable valve timing (VVT) system, which is critical for …
The P261C trouble code is an OBD-II diagnostic code that indicates a problem with the coolant pump “B” control circuit. This code specifically points to a low voltage condition in the control circuit, which can lead to severe issues with the vehicle’s cooling system. When the engine control module (ECM) detects that the voltage in …
The P0366 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the camshaft position sensor “B” circuit range or performance for bank 1 of the engine. This code is part of the OBD-II system, which monitors various vehicle functions to ensure optimal performance and emissions control. When the powertrain control module …
The P1105 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Manifold Absolute Pressure (MAP) sensor or the Barometric Pressure (BARO) sensor circuit. This code is typically triggered when the Engine Control Module (ECM) detects an issue with the pressure readings from these sensors, which are crucial for determining engine …
The P1225 trouble code is a diagnostic trouble code (DTC) that indicates a problem related to the throttle control system in various vehicles. Specifically, it generally refers to a “Closed Throttle Position Learning Performance Problem.” This code can affect engine performance, fuel efficiency, and overall drivability. Understanding this code is crucial for vehicle owners and …
The P0561 trouble code indicates a problem with the vehicle’s electrical system, specifically an “unstable voltage” detected by the Powertrain Control Module (PCM). This code is triggered when the PCM identifies that the voltage levels in the electrical system are fluctuating outside of the normal operating range. Such fluctuations can lead to various issues, including …
The P1519 trouble code indicates a malfunction related to the Intake Manifold Runner Control (IMRC) system. This code is critical as it signifies that the IMRC is stuck in the closed position, which can severely affect engine performance, fuel efficiency, and emissions. The IMRC is responsible for optimizing airflow into the engine by adjusting the …
The P1476 trouble code is associated with the Evaporative Emission Control (EVAP) system and specifically relates to insufficient vacuum in the system. This code indicates that the Engine Control Module (ECM) has detected a problem with the Leak Detection Pump (LDP) or a leak in the EVAP system. P1476 Code Meaning P1476 Code Common Causes …
The P0471 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the exhaust pressure sensor circuit, specifically its range or performance. When this code is triggered, it typically means that the Powertrain Control Module (PCM) has detected a voltage reading from the exhaust pressure sensor that falls outside of the expected …
The P0571 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the cruise control/brake switch circuit, specifically known as “Cruise Control/Brake Switch A Circuit Malfunction.” This code is logged when the powertrain control module (PCM) detects an issue with the brake switch or its circuit, which is essential for the proper …
