The P119A trouble code is a diagnostic trouble code (DTC) that indicates a malfunction related to the fuel pressure sensor (G247) in a vehicle’s engine management system. This code is primarily associated with fuel delivery issues, which can lead to poor engine performance, reduced fuel efficiency, and even engine misfires. Understanding the causes and solutions … Read more
The P1723 trouble code is a diagnostic trouble code (DTC) that indicates a problem related to the automatic transmission control relay, specifically indicating that it is “stuck on.” This code is often associated with issues in the vehicle’s powertrain, particularly affecting the transmission’s operation. When this code is triggered, it can lead to various symptoms … Read more
The P1297 trouble code is a diagnostic trouble code (DTC) that indicates an issue related to the engine management system, specifically concerning the camshaft timing or pressure drop between components in various vehicle models. This code can manifest in different ways depending on the make and model of the vehicle, but it generally signifies that … Read more
The P0657 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the actuator supply voltage “A” circuit. This code is triggered when the Powertrain Control Module (PCM) detects an abnormal voltage reading from the actuator circuit, often due to an open circuit, which signifies a disconnection or failure in wiring. Actuators … Read more
The P1871 trouble code is a diagnostic trouble code (DTC) that indicates an “Undefined Gear Ratio” in the vehicle’s transmission system. This code is primarily associated with automatic transmissions and signals that the vehicle’s powertrain control module (PCM) has detected a discrepancy between the expected and actual gear ratios. When this code is triggered, it … Read more
The P203B trouble code is a diagnostic code related to the reductant level sensor circuit in diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems. This code indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an issue with the performance or range of the reductant level sensor circuit. Understanding … Read more
