P0452

2017-10-10

Description:

  • The fault code P0452 indicates that there is a problem with the evaporative emission control system pressure sensor circuit, where the input signal is lower than what is expected by the engine control module. This fault code can cause issues with the engine's performance and may fail emissions testing.

Possible Symptoms:

  • Illuminated check engine light

  • Failed emissions testing

  • Difficulty starting the engine

  • Reduced engine power or acceleration

Possible Causes:

  • Faulty or failed evaporative emission control system pressure sensor

  • Damaged or corroded wiring or connections within the circuit

  • Loose or broken vacuum lines within the evaporative emission control system

  • Failed engine control module (ECM)

Related Parts:

  • Evaporative Emission (EVAP) Pressure Sensor: The EVAP system prevents petrol vapors from escaping into the atmosphere from the fuel tank and fuel system. The pressure sensor monitors the pressure in the EVAP system. Problems in this car's flow valve will lead to fuel loss

Possible Solutions:

  • Replace the evaporative emission control system pressure sensor

  • Inspect and repair any damaged or corroded wiring or connections within the circuit

  • Inspect and repair any loose or broken vacuum lines within the system

  • Replace the engine control module (ECM) if necessary
