The P1507 trouble code is associated with the Idle Air Control (IAC) system, indicating that the engine’s idle speed is lower than expected. This code typically arises when the Engine Control Module (ECM) detects that the idle air control valve is not maintaining the correct idle speed, leading to performance issues. The IAC valve is …
The P01444 trouble code is a diagnostic trouble code (DTC) that pertains to the vehicle’s evaporative emission control (EVAP) system. Specifically, it indicates an issue with the EVAP canister purge volume control solenoid valve, which is responsible for regulating the flow of fuel vapors from the EVAP canister to the engine intake manifold. When this …
The P1492 trouble code indicates an issue with the battery temperature sensor circuit, specifically that the voltage is too high. This code is typically seen in Chrysler, Dodge, and Jeep vehicles, though it can appear in other makes as well. When this code is triggered, it means the Powertrain Control Module (PCM) has detected a …
The P2014 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Intake Manifold Runner Position Sensor/Switch Circuit for Bank 1. This code is crucial for vehicle performance as it pertains to the intake manifold runner control (IMRC) system, which plays a significant role in optimizing engine airflow based on various …
The P0690 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the ECM/PCM power relay sense circuit. This code is triggered when the powertrain control module (PCM) detects an abnormal voltage level in the relay circuit, which is responsible for supplying power to the PCM and its control circuits. Understanding this …
The P0503 trouble code refers to an issue with the Vehicle Speed Sensor (VSS) “A,” indicating that the powertrain control module (PCM) has detected an intermittent, erratic, or high voltage input signal from this sensor. This code is particularly relevant for vehicles manufactured since 1996, as it applies to all OBD-II compliant vehicles. The VSS …
The P13C0 trouble code is a diagnostic trouble code (DTC) that indicates a fault in the Variable Valve Timing (VVT) system, specifically related to the VANOS intake control. This code typically arises in vehicles equipped with BMW engines, where it signifies that the engine control module (ECM) has detected a malfunction in the camshaft timing …
The P0795 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Pressure Control Solenoid ‘C’ of an automatic transmission. This code is recognized across various OBD-II compliant vehicles and is crucial for maintaining optimal transmission performance. When this code is triggered, it signifies that the Powertrain Control Module (PCM) has …
The P0714 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the transmission fluid temperature sensor circuit. Specifically, it signifies that the Powertrain Control Module (PCM) has detected an intermittent signal from the transmission fluid temperature sensor ‘A’. This sensor plays a critical role in monitoring the temperature of the transmission …
The P11AA trouble code is a diagnostic trouble code (DTC) that indicates an issue with the camshaft adjustment actuator in a vehicle’s engine, specifically related to cylinder 3. This code is primarily seen in vehicles equipped with variable valve timing (VVT) systems, which optimize engine performance and efficiency by adjusting the timing of the intake …
