The P0021 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the camshaft position timing in Bank 2 of the engine, specifically denoting that the camshaft timing is over-advanced. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s engine and transmission systems.
The P0132 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit, specifically a high voltage reading from the oxygen sensor located in Bank 1, Sensor 1. This sensor is crucial for monitoring the oxygen levels in the exhaust gases and plays a vital role in optimizing engine
The P0123 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Throttle/Pedal Position Sensor (TPS) circuit, specifically showing a high input signal. This code is common across many vehicles equipped with OBD-II systems and can lead to various performance issues if not addressed promptly. The throttle position sensor plays a
The P0117 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Engine Coolant Temperature (ECT) sensor circuit. Specifically, it signifies that the voltage input from the ECT sensor to the vehicle’s Powertrain Control Module (PCM) is lower than expected. This can lead to various engine performance issues, including overheating, poor
The P0449 trouble code is a diagnostic trouble code (DTC) indicating a malfunction in the evaporative emission control (EVAP) system, specifically related to the vent valve or solenoid circuit. This code is crucial as it signals potential issues with the vehicle’s ability to manage fuel vapors, which can lead to increased emissions and possible failure
The P0401 trouble code is a diagnostic trouble code (DTC) that indicates “Exhaust Gas Recirculation (EGR) Flow Insufficient Detected.” This code is triggered when the engine control module (ECM) detects that the EGR system is not allowing enough exhaust gases to recirculate into the intake manifold. The EGR system plays a crucial role in reducing
The P0700 trouble code is a generic diagnostic trouble code (DTC) that indicates a malfunction in the transmission control system of a vehicle. This code is triggered when the Transmission Control Module (TCM) detects an issue affecting the automatic transmission’s performance. The TCM is responsible for managing the transmission’s operation, and when it identifies a
The P0440 trouble code indicates a malfunction in the Evaporative Emission Control (EVAP) system, specifically noting a large leak. This code is generated when the vehicle’s engine control module (ECM) detects that the EVAP system is unable to maintain the required pressure levels, which can lead to increased emissions and potential environmental harm. Understanding this
The P0102 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the Mass Air Flow (MAF) sensor circuit, specifically a low voltage input. This code is triggered when the Engine Control Module (ECM) detects that the MAF sensor is not providing an adequate signal regarding the amount of air entering the
The P0299 code is a diagnostic trouble code (DTC) that indicates a Turbocharger/Supercharger “A” Underboost Condition. This occurs when the vehicle’s engine control unit (ECU) detects that the boost pressure generated by the turbocharger or supercharger is lower than the required level for optimal engine performance. This underboost condition can lead to decreased engine power,
The P0325 trouble code is an OBD-II diagnostic code that indicates a malfunction in the knock sensor circuit of your vehicle, specifically for Sensor 1 on Bank 1. The knock sensor plays a critical role in monitoring engine vibrations and detecting knocking or pinging during combustion. When the sensor detects an abnormality, it sends a
