P0453

2017-10-10

Description:

  • The fault code P0453 indicates that the evaporative emissions control system pressure sensor is detecting a high input signal. This may cause issues with the emissions system and trigger the check engine light.

Possible Symptoms:

  • Illuminated check engine light

  • Failed emissions test

  • Increased fuel consumption

  • Rough idling or stalling

  • Fuel odor from the vehicle

Possible Causes:

  • Faulty evaporative emissions control system pressure sensor

  • Wiring or electrical connector issues in the pressure sensor circuit

  • Failed fuel tank pressure sensor

  • 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 emissions control system pressure sensor

  • Check and repair any damaged wiring or connections in the pressure sensor circuit

  • Replace the fuel tank pressure sensor if necessary

  • Replace the engine control module (ECM) if necessary
