The P0629 diagnostic trouble code (DTC) indicates a problem with the fuel pump “A” control circuit, specifically that the circuit is experiencing a higher than normal voltage. This code is typically set when the Powertrain Control Module (PCM) or Engine Control Module (ECM) detects an issue with the fuel pump’s electrical control system. Understanding and …
The P0196 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the engine oil temperature sensor’s range or performance. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various engine parameters to ensure optimal performance and emissions control. When the engine control module (ECM) detects that the …
The P0040 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the oxygen sensor signals in a vehicle’s engine management system. Specifically, it refers to the situation where the signals from the first oxygen sensors (O2 sensors) on Bank 1 and Bank 2 have been swapped. This condition can lead to …
The P0462 code is a diagnostic trouble code (DTC) that indicates a problem with the fuel level sensor circuit. When the powertrain control module (PCM) detects a low input signal from the fuel level sensor, it triggers this code. Understanding and addressing this issue is crucial for maintaining accurate fuel level readings and ensuring proper …
The P2028 trouble code is part of the On-Board Diagnostics II (OBD-II) system, specifically relating to the Evaporative Emissions (EVAP) system. This code indicates an intermittent issue with the Fuel Vapor Temperature Sensor circuit. When the Engine Control Module (ECM) detects that the voltage from the fuel vapor temperature sensor is outside the normal operating …
The P0880 trouble code is a diagnostic trouble code (DTC) that signifies an issue with the Transmission Control Module (TCM) power input signal. When the Powertrain Control Module (PCM) detects a malfunction in the TCM’s power input circuit, it triggers this code. This can lead to various performance issues in the vehicle, particularly concerning the …
The P060A trouble code is a generic diagnostic trouble code (DTC) that indicates an issue with the internal control module’s monitoring processor performance. This code is primarily associated with the Engine Control Module (ECM) or Powertrain Control Module (PCM) in vehicles equipped with OBD-II systems. When the PCM detects a malfunction in its internal processor …
The P0724 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the torque converter brake switch B circuit. This code is applicable to all 1996 and newer vehicles equipped with automatic transmissions. When the powertrain control module (PCM) detects a high electrical condition in the brake switch circuit, it triggers the …
The P20D4 trouble code is a diagnostic trouble code (DTC) indicating a problem with the Exhaust Aftertreatment Fuel Injector ‘B’ control circuit, specifically a high voltage condition. This code is relevant to many diesel-powered vehicles equipped with an exhaust aftertreatment system (EAS), which is crucial for reducing harmful emissions. When the powertrain control module (PCM) …
The P0025 trouble code indicates a problem with the exhaust camshaft position timing, specifically that it is over-retarded on Bank 2 of the engine. This code is part of the OBD-II system, which monitors various engine and vehicle parameters to ensure optimal performance and emissions control. When the Powertrain Control Module (PCM) detects that the …
