The P1743 trouble code is an OBD-II diagnostic code that indicates a malfunction in the torque converter clutch solenoid circuit. This code typically arises when the vehicle’s powertrain control module (PCM) detects an issue with the torque converter clutch (TCC) solenoid, which is responsible for locking and unlocking the torque converter to optimize engine performance …
The P0041 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor signals in a vehicle’s engine management system. Specifically, it signifies that the signals from the oxygen sensors located downstream from the catalytic converters have been swapped between Bank 1 Sensor 2 and Bank 2 Sensor 2. This …
The P1418 trouble code is a manufacturer-specific diagnostic code related to the secondary air injection system. This code typically indicates a malfunction in the control circuit of the secondary air injection system relay ‘A’. The secondary air injection system is designed to reduce emissions by introducing fresh air into the exhaust stream, promoting the oxidation …
The P1764 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the governor pressure sensor circuit in vehicles equipped with automatic transmissions. This code is part of the OBD-II system, which monitors the performance of various vehicle systems, including the powertrain and emissions controls. When the PCM (Powertrain Control Module) detects …
The P0990 trouble code indicates an issue with the Transmission Fluid Pressure Sensor/Switch ‘E’ Circuit, specifically that the circuit is reading a high voltage. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s powertrain, including the engine and transmission. When this code is triggered, it suggests …
The P150A00 code is a powertrain diagnostic trouble code (DTC) that indicates an issue with the engine off timer performance. This code is typically associated with the vehicle’s fuel system and engine control module (ECM). When this code is triggered, it means the ECM has detected a discrepancy in the engine off timer function, which …
The P0652 trouble code indicates an issue with the “Sensor Reference Voltage ‘B’ Circuit,” which is essential for the proper functioning of various sensors in a vehicle’s powertrain system. When this code is triggered, it signifies that the Powertrain Control Module (PCM) has detected a low reference voltage in the circuit designated as “B.” This …
The P0458 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Evaporative Emission System (EVAP) purge control valve circuit. When this code is triggered, it means that the powertrain control module (PCM) has detected a low voltage reading in the circuit associated with the EVAP purge control valve. This system …
The P2419 trouble code is a diagnostic trouble code (DTC) that indicates an issue within the Evaporative Emission Control (EVAP) system, specifically related to the switching valve control circuit. This code can be triggered when the Powertrain Control Module (PCM) detects that the EVAP system’s leak detection pump is not functioning correctly, which can lead …
The P00BC trouble code is a diagnostic error code that indicates a problem with the Mass Air Flow (MAF) sensor or its circuit, specifically denoting that the air flow is too low. This code is triggered when the Powertrain Control Module (PCM) detects that the actual frequency signal from the MAF sensor does not meet …
