The P0874 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Transmission Fluid Pressure Sensor/Switch “C” Circuit. This code is typically triggered when the powertrain control module (PCM) detects an intermittent fault in the circuit related to the transmission fluid pressure sensor. The sensor plays a crucial role in monitoring
The P01336 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the crankshaft position sensor (CKP) or the camshaft position sensor (CMP) in relation to the engine control module (ECM). This code typically arises when the ECM detects that the crankshaft position system variation has not been learned or is out
The P20CD trouble code is an OBD-II diagnostic code that indicates a problem with the Exhaust Aftertreatment Fuel Injector ‘A’ control circuit. This code is specifically related to diesel engines, where the exhaust aftertreatment system plays a crucial role in reducing harmful emissions. When the P20CD code is triggered, it signifies that the control circuit
The P0291 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel injector circuit for cylinder number 11 in your vehicle’s engine. Specifically, it denotes a low voltage condition detected by the powertrain control module (PCM). This code is applicable to all OBD-II equipped vehicles, and while the core meaning
The P2526 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the vacuum reservoir pressure sensor circuit. Specifically, it refers to the range or performance of this circuit being outside the manufacturer’s specified limits. This code is applicable to all OBD-II compliant vehicles, which have been manufactured since 1996. Understanding this
The P0856 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the traction control input signal. This code is primarily associated with vehicles equipped with electronic traction control systems, which are designed to enhance vehicle stability and prevent wheel spin during acceleration. When the powertrain control module (PCM) detects an issue
The P2598 trouble code is a diagnostic trouble code (DTC) that indicates a performance issue with the Turbocharger Boost Control Position Sensor ‘A’. This code typically signifies that the sensor is reporting low performance, which can lead to reduced engine efficiency and performance.

The P061B trouble code is a diagnostic trouble code (DTC) that indicates an issue with the powertrain control module (PCM) related to torque calculation performance. Specifically, it signifies that the PCM has detected a discrepancy in the expected torque calculations, which can lead to various engine performance issues. This code is prevalent across many vehicle
The P0174 trouble code is a diagnostic trouble code (DTC) that indicates a “System Too Lean (Bank 2)” condition in your vehicle’s engine. This code is triggered when the engine control module (ECM) detects that the air-fuel mixture in bank 2 of the engine is too lean, meaning there is more air than fuel in
The P0561 trouble code is a diagnostic trouble code (DTC) that signifies an issue with the vehicle’s electrical system, specifically indicating “System Voltage Unstable.” This code is triggered when the Powertrain Control Module (PCM) detects that the voltage in the vehicle’s electrical system is outside the normal operating range. This can lead to various symptoms
The P07E9 trouble code is an OBD-II diagnostic trouble code that indicates a problem with the transmission range control circuit performance. This code is typically associated with issues in the transmission system, particularly regarding how the vehicle’s transmission control module (TCM) interprets signals from the transmission range sensor. Understanding this code is essential for vehicle
