The P0316 code is a diagnostic trouble code (DTC) that indicates an engine misfire detected during the first 1,000 revolutions after startup. This code is set when the vehicle’s powertrain control module (PCM) detects a misfire condition in one or more cylinders immediately after the engine is started. Understanding and addressing this code promptly is …
The P2201 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the NOx (Nitrogen Oxide) sensor circuit, specifically related to its range or performance in Bank 1 of the engine. This code is primarily associated with vehicles equipped with diesel engines, where the NOx sensor plays a critical role in monitoring …
The P0845 trouble code indicates a malfunction within the Transmission Fluid Pressure Sensor/Switch “B” Circuit. 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 the Powertrain Control Module (PCM) detects an abnormal voltage reading from the transmission fluid pressure …
The P0379 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the timing reference high-resolution signal B. Specifically, it signifies that the Powertrain Control Module (PCM) is not receiving any pulses from the engine position sensor, which is crucial for determining engine speed and position. This code is applicable to OBD-II …
The P0879 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Transmission Fluid Pressure Sensor/Switch ‘D’ Circuit. This code is triggered when the powertrain control module (PCM) detects an intermittent problem with the transmission fluid pressure sensor or switch, which plays a crucial role in monitoring the transmission fluid pressure. …
The P21AB trouble code is an OBD-II diagnostic code that indicates a problem with the reductant level sensor ‘B’ circuit, specifically that it is reading high. This code is primarily associated with diesel vehicles equipped with selective catalytic reduction (SCR) systems, which use diesel exhaust fluid (DEF) to reduce harmful emissions. Understanding this code is …
The P0020 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Intake “A” Camshaft Position Actuator Circuit/Open (Bank 2). This code is triggered when the powertrain control module (PCM) detects a fault in the variable valve timing (VVT) system, specifically relating to the camshaft position actuator circuit. The VVT system …
The P2694 trouble code is an OBD-II diagnostic trouble code that indicates a specific issue related to the fuel injection system of a vehicle. More specifically, it refers to the “Cylinder 9 Injector Data Incompatible.” This code is triggered when the engine control module (ECM) detects that the data being received from the injector for …
The P0238 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the turbocharger or supercharger boost sensor circuit. Specifically, it refers to a high input signal from the boost pressure sensor, which is crucial for monitoring the amount of boost being generated by the turbocharger or supercharger. When this code is …
The P1460 trouble code is an OBD-II diagnostic code that indicates a problem with the vehicle’s throttle/pedal position sensor or switch. This code typically signifies an intermittent issue within the circuit, which can affect engine performance and overall vehicle operation. When this code is triggered, it often results in the illumination of the check engine …
