What is Evaporative Emission system pressure sensor Switch High?
A P0453 code means that a reading from the engine’s evaporative pressure sensor is higher than normal, indicating changes in pressure that are out of factory specification.
Where is the Evaporative Emission system pressure sensor Switch?
The EVAP Pressure Sensor, also known as a Fuel Tank Pressure (FTP) Sensor is a device that measures air pressure or vacuum in the evaporative emission (EVAP) system. This sensor is typically found on top of or inside of the fuel tank.
How does the evaporative emission system control system work?
The Evaporative Emission System ( EVAP) control system pressure sensor detects pressure in the purge line. The sensor output voltage to the Engine Control Module ( ECM) increases as pressure increases. The EVAP control system pressure sensor is not used to control the engine system.
Is there a pressure sensor in the EVAP system?
The EVAP system comes with a pressure sensor that regularly checks the integrity of the system. The EVAP system tests the pressure sensor from time to time to make sure there are no leaks in the system.
What is the code for the EVAP system?
The powertrain control module (PCM) routinely checks the EVAP system for any leaks and tests the ability to purge fuel vapor into the engine. If the sensor signal voltage exceeds a specific value for a certain amount of time, the PCM may log code P0453.
What are the codes for evaporative emission problems?
Related evaporative emission trouble codes include P0450, P0451, P0452, P0454, P0455, P0456, P0457, P0458, and P0459. There will likely be no noticeable symptoms along with this code other than the MIL (Malfunction Indicator Lamp), commonly known as Check Engine Light illumination. However, there may be noticeable fuel odors in some cases.
