The P1614 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction related to the vehicle’s immobilizer system. Specifically, it often signifies that the engine control module (ECM) is not receiving the correct signals from the immobilizer control module (ICM). This situation can prevent the engine from starting or cause it to stall …
The P0261 trouble code indicates a problem with the fuel injector circuit for cylinder 1, specifically a low voltage condition. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various engine and transmission parameters. When the Powertrain Control Module (PCM) detects that the voltage in the injector circuit for cylinder 1 …
The P2798 trouble code is an OBD-II diagnostic code that indicates an issue with the auxiliary transmission fluid pump control circuit, specifically denoting a low voltage condition. This code is crucial for vehicle owners and DIY mechanics to understand, as it directly affects the performance and reliability of the vehicle’s transmission system. The auxiliary transmission …
The P2813 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the pressure control solenoid “G” in an automatic transmission system. This code is triggered when the Powertrain Control Module (PCM) detects that the control circuit for this solenoid is operating outside of its normal range. The pressure control solenoids play …
The P0299 trouble code is a generic powertrain code that indicates an underboost condition in a turbocharged or supercharged engine. This code is set when the engine control module (ECM) detects that the actual boost pressure is significantly lower than the desired boost pressure for a specified period of time. Understanding and addressing this code …
The P0104 trouble code is a diagnostic trouble code (DTC) that indicates an intermittent or erratic fault in the Mass Air Flow (MAF) sensor circuit. The MAF sensor plays a critical role in measuring the amount of air entering the engine, which is essential for determining the correct fuel-to-air ratio for optimal engine performance. When …
The P0049 trouble code is an OBD-II diagnostic trouble code that indicates a problem with the turbocharger or supercharger system in a vehicle. Specifically, it refers to a “Turbocharger/Supercharger ‘A’ Turbine Overspeed” condition. This code is set when the powertrain control module (PCM) detects that the turbine of the turbocharger or supercharger is spinning faster …
The P3451 trouble code is a diagnostic code related to the cylinder deactivation system, specifically for cylinder 7. This code indicates that the Engine Control Module (ECM) has detected a low voltage or resistance in the circuit controlling the deactivation or intake valve for cylinder 7. Understanding and addressing this code is crucial for maintaining …
The P2251 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor negative current control circuit, specifically for Bank 1 Sensor 1. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors vehicle performance and emissions. When the Powertrain Control Module (PCM) detects a malfunction in …
The P054A trouble code is a diagnostic trouble code (DTC) that indicates a problem with the camshaft timing in relation to the variable valve timing (VVT) system, specifically during cold starts. This code signals that the powertrain control module (PCM) has detected an “over-advanced” position of the camshaft on bank 1, which can lead to …
