The P1441 trouble code is a manufacturer-specific diagnostic code that indicates a malfunction in the evaporative emission control (EVAP) system. Specifically, it signifies that the engine control module (ECM) has detected fuel vapor flow through the EVAP system during a non-purge condition, which should not occur. This issue can lead to increased emissions and may …
The P1955 trouble code is an OBD-II diagnostic code that indicates a malfunction related to the powertrain of a vehicle. Specifically, it often points to issues with the injector circuit or communication errors between the glow plug control module and the powertrain control module (PCM). When this code appears, it can trigger a check engine …
The P1093 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel trim for Bank 1 of a vehicle’s engine. Specifically, it signifies that the fuel trim is out of range, which can lead to performance issues, reduced fuel efficiency, and increased emissions. Understanding this code is crucial for vehicle …
The P0730 code is a diagnostic trouble code (DTC) that indicates an incorrect gear ratio detected by the vehicle’s powertrain control module (PCM) or transmission control module (TCM). This code is typically set when there’s a significant discrepancy between the rotational speed of the transmission’s input shaft and output shaft, often suggesting transmission slippage or …
The P0760 diagnostic trouble code (DTC) indicates a malfunction in the shift solenoid C circuit within the transmission control system. This code is primarily associated with automatic transmissions and signals that there is an issue affecting the vehicle’s ability to shift gears properly. Understanding this code is crucial for vehicle owners and DIY mechanics, as …
The P0207 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the fuel injector circuit for Cylinder 7. This code is part of the OBD-II system used in modern vehicles to monitor engine performance and emissions. When the Engine Control Module (ECM) detects an issue with the injector circuit, it triggers …
The P1296 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the engine cooling system, specifically related to the coolant temperature sensor or thermostat. This code is commonly associated with various vehicles, particularly those from the Volkswagen Group, including Audi and SEAT models. When this code appears, it often triggers the …
The P0597 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the thermostat heater control circuit, specifically that it is open. 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 thermostat’s control …
The P2239 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor’s positive current control circuit in the engine management system. Specifically, it refers to a high voltage condition detected by the powertrain control module (PCM) in the upstream oxygen sensor (O2 sensor) located on bank 1 of the …
The P0055 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the heater circuit of the heated oxygen sensor (HO2S) located on Bank 1, Sensor 3. This code is triggered when the Engine Control Module (ECM) detects an abnormal resistance in the heater circuit of the oxygen sensor. The oxygen sensor …
