2025年1月22日 · What does the P0451 error code mean? The P0451 diagnostic trouble code stands for "Evaporative Emission System Pressure Sensor Range/Performance." This code is triggered when the engine...

P0451 stands for Evaporative emission control system pressure switch range/performance. This error code is set when the PCM detects improper, erratic, or otherwise incorrect signal voltage from the EVAP sensor.

The P0451 code stands for “Evaporative Emission System Pressure Sensor/Switch.” What does the P0451 Code Mean? The P0451 code indicates that your powertrain control module (PCM) detects an improper or incorrect voltage signal from the evaporative emission control system pressure sensor .

2022年6月28日 · What are the possible causes of OBDII code P0451 in a Chevrolet indicating Fuel Tank Pressure Sensor Performance issues? - Causes may include a faulty fuel tank pressure sensor, damaged wiring connected to the sensor, a leak in the fuel system, or a malfunctioning evaporative emissions control system.

If your OBD-II vehicle has presented a code P0451, it simply means that the powertrain control module (PCM) has detected a malfunction in the pressure sensor circuit of the evaporative emissions (EVAP) system.

2025年1月11日 · Code P0451 is a diagnostic trouble code (DTC) related to the evaporative emission control (EVAP) system in your vehicle. Specifically, it indicates an issue with the EVAP system pressure sensor or switch range/performance.

2024年12月18日 · The P0451 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Evaporative Emission Control (EVAP) system’s pressure sensor or switch range/performance. This code is triggered when the Powertrain Control Module (PCM) detects that the EVAP pressure sensor is reporting values outside the manufacturer-specified range.

2024年5月30日 · The P0451 trouble code indicates an issue with the evaporative emission control (EVAP) system pressure sensor. This sensor monitors the pressure within the fuel tank to ensure there are no leaks in the EVAP system, which helps control the release of …

2017年1月26日 · If the ECM detects an unexpected pressure reading, such as still holding a vacuum when the system is purging, it will detect this as a fault, set a DTC (diagnostic trouble code) in system memory, and illuminate the MIL (malfunction indicator lamp). DTC P0451 is defined as Evaporative Emission Control System Pressure Sensor Range/Performance.

P0451 is an OBD-II Code that refers to Evaporative Emission Control System Pressure Sensor Range/Performance. A P0451 code is a manufacturer specific code usually found either in Audi, GMC Toyota, Dodge, Ram, Ford and VW vehicles.
