The P0220 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Throttle/Pedal Position Sensor/Switch “B” circuit. This code is triggered when the Powertrain Control Module (PCM) detects a voltage or resistance reading from the throttle/pedal position sensor that is outside of the specified range. The “B” in the code refers …
The P1291 trouble code is a diagnostic trouble code (DTC) that signifies an issue with the intake air heater system, specifically indicating that there is “No Temperature Rise Seen From Intake Air Heater.” This code is commonly associated with diesel engines, particularly in vehicles equipped with grid heaters designed to warm the intake air for …
The P2219 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the NOx (Nitrogen Oxide) sensor heater control circuit on bank 2 of an engine. This code is triggered when the Engine Control Module (ECM) detects a voltage reading that is lower than expected from the NOx sensor’s heater control circuit. …
The P0002 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the fuel volume regulator control circuit, specifically regarding its range or performance. This code is set when the engine control module (ECM) detects that the fuel volume regulator is not functioning within its specified parameters. The fuel volume regulator is …
A P0914 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the gear shift position circuit in a vehicle’s transmission system. This code is triggered when the Powertrain Control Module (PCM) detects an electrical fault related to the gear shift position sensor, which plays a crucial role in informing the PCM …
The P0765 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the transmission’s Shift Solenoid “D.” This code is commonly encountered in vehicles equipped with automatic transmissions. The shift solenoids are crucial components that control the flow of hydraulic fluid within the transmission, allowing for smooth gear shifts. When the Transmission …
The P0643 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the “Sensor Reference Voltage ‘A’ Circuit High.” This code is triggered when the Powertrain Control Module (PCM) detects that the reference voltage supplied to a specific sensor is higher than expected, typically exceeding the standard 5 volts. This condition can …
The P052E trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the Positive Crankcase Ventilation (PCV) regulator valve performance. This issue arises when the Powertrain Control Module (PCM) detects that the PCV system is not functioning correctly, which can lead to poor engine performance, increased emissions, and potential engine damage if …
The P0036 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the heated oxygen sensor (HO2S) control circuit, specifically for bank 1, sensor 2. This code is set when the powertrain control module (PCM) detects that the downstream oxygen sensor is not functioning correctly. The downstream oxygen sensor is crucial for …
The P014B diagnostic trouble code (DTC) pertains to an issue with the oxygen sensor in a vehicle’s exhaust system, specifically indicating a delayed response from the downstream oxygen sensor located on bank 2 of the engine. This code is triggered when the powertrain control module (PCM) detects that the oxygen sensor is not responding as …
