The P2178 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel control system of a vehicle. Specifically, it means “System Too Rich Off Idle Bank 1,” which refers to the engine bank containing cylinder number one. This code is triggered when the engine control module (ECM) detects that the …
The P1159 trouble code is a manufacturer-specific diagnostic code that generally indicates an issue with the fuel trim system in a vehicle. This code is commonly associated with BMW and Honda vehicles, though it can appear in other makes as well. When the engine control module (ECM) detects that the fuel trim is outside of …
The P115C trouble code is a diagnostic trouble code (DTC) that indicates an issue related to the mass air flow (MAF) sensor in vehicles. Specifically, it signifies that the air mass entering the engine is lower than expected compared to the vehicle’s model specifications. This can lead to various performance issues, including reduced power, increased …
The P1434 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction related to the additive pump in diesel vehicles, particularly those equipped with a diesel particulate filter (DPF) and an additive system. This code is commonly associated with issues in the Eolys additive system, which is responsible for injecting a fuel additive …
The P0068 trouble code, also known as “MAP/MAF – Throttle Position Correlation,” is a diagnostic code that indicates a discrepancy between the readings from the Manifold Absolute Pressure (MAP) sensor, Mass Airflow (MAF) sensor, and Throttle Position Sensor (TPS). This code is typically set when the engine control module (ECM) detects that these sensor readings …
The P0711 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the transmission fluid temperature sensor circuit. Specifically, it refers to the Transmission Fluid Temperature Sensor ‘A’ Circuit Range/Performance. This code is triggered when the Powertrain Control Module (PCM) detects that the temperature readings from the transmission fluid temperature sensor are …
The P0112 trouble code indicates an issue with the intake air temperature (IAT) sensor circuit, specifically that the voltage being reported is lower than the expected range. This code is a generic OBD-II diagnostic trouble code that applies to most vehicles equipped with an OBD-II system. When this code appears, it suggests that the engine …
The P1074 trouble code is an OBD-II diagnostic code that indicates an issue with the fuel and air metering system, specifically related to the injector circuit malfunction in cylinder 4. This code is triggered when the vehicle’s Powertrain Control Module (PCM) detects that the fuel injection system is not performing as expected, leading to potential …
The P1DDD diagnostic trouble code (DTC) is a manufacturer-specific powertrain code related to transmission control issues. This code typically indicates a problem with the Transmission Control Module (TCM) monitoring processor performance, specifically an inability to disengage drive or reverse gears. When this code appears, it usually signifies a critical issue that requires immediate attention to …
When your vehicle’s onboard diagnostics system triggers the P000F trouble code, it indicates that the fuel system over pressure relief valve has been activated. This code is part of the OBD-II diagnostic trouble codes that relate to the powertrain, specifically indicating that the powertrain control module (PCM) has detected excessive fuel pressure. The activation of …
