The P2121 trouble code is part of the OBD-II diagnostic system and indicates a problem with the Throttle/Pedal Position Sensor/Switch ‘D’ Circuit Range/Performance. This code is critical for understanding how your vehicle’s throttle system is functioning and can significantly impact performance if not addressed. The throttle position sensor (TPS) plays a vital role in relaying …
The P006800 trouble code is a diagnostic trouble code (DTC) that indicates a correlation issue between the Mass Air Flow (MAF) sensor, the Manifold Absolute Pressure (MAP) sensor, and the Throttle Position (TP) sensor. When the Engine Control Module (ECM) detects that the readings from these sensors do not align as expected, it triggers the …
The P1871 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the vehicle’s transmission system, specifically related to an undefined gear ratio. This code is typically associated with automatic transmissions and can lead to significant performance issues if not addressed promptly. When the vehicle’s onboard computer detects that the actual gear …
The P1577 trouble code is a diagnostic trouble code (DTC) that typically indicates an issue with the right electro-hydraulic engine mount solenoid valve in various vehicle models, particularly those manufactured by Volkswagen, Audi, Skoda, and Seat. This solenoid valve is crucial for managing the hydraulic engine mount system, which helps minimize engine vibrations and noise …
The P2006 diagnostic trouble code (DTC) is a generic powertrain code related to the intake manifold runner control system. This code indicates that the powertrain control module (PCM) has detected an issue with the intake manifold runner control (IMRC) actuator for engine bank 1, specifically that it is stuck in the closed position. P2006 Code …
The P0826 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Up and Down Shift Switch Circuit in vehicles equipped with automatic transmissions that allow manual shifting. This code is triggered when the Powertrain Control Module (PCM) detects a malfunction in the electrical circuit associated with the upshift/downshift switch, which …
The P06E9 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the engine starter performance. This code is part of the OBD-II (On-Board Diagnostics II) system, which monitors various components of a vehicle’s powertrain. When the powertrain control module (PCM) detects that the engine is not rotating as expected during a …
The P1303 trouble code indicates a misfire detected in cylinder number three of a vehicle’s engine. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors the performance of the engine and its components. When the Engine Control Module (ECM) detects that a cylinder is not firing correctly, it triggers the P1303 …
The P1602 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the communication between the Engine Control Module (ECM) and the immobilizer system. This code is particularly significant as it relates to your vehicle’s security system, which prevents the engine from starting without the correct key. When the ECM cannot establish …
The P0A9E trouble code is a diagnostic trouble code (DTC) related to hybrid and electric vehicles, specifically indicating an issue with the Hybrid Battery Temperature Sensor ‘A’ Circuit High. This code is part of the OBD-II system, which monitors various components of the vehicle’s powertrain. When this code is triggered, it typically signifies that the …
