What is the pressure sensor code on my 1999 Mercury Cougar?
My 1999 Mercury Cougar is generating code P0453. I’ve replaced the Pressure Feedback Sensor and the Vacuum Regulator Sensor and still no luck. In an attempt to isolate the problem, I unplugged every sensor I could find, one at a time (except the fuel tank pressure sensor) and verified a second code …
What does the pressure sensor on Ford p0453 do?
The EVAP (Evaporative Emissions) System allows fuel tank vapors to be purged into the engine and burnt rather than expelled into the atmosphere as harmful emissions. The EVAP system contains a pressure sensor to check the integrity of the system. Periodically, the EVAP system performs a pressure test to check that there are no leaks in the system.
What causes a trouble code on a p0453 DTC?
A P0453 DTC trouble code may be caused by one or more of the following: Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank Using an scan tool access FTP sensor value with Key on Engine off (KOEO). Normal value is usually somewhere near 2.5 Volts at atmospheric pressure (may fluctuate some due to altitude).

What causes an EVAP pressure sensor to code p0453?
In short, the following are common causes of the code P0453: Faulty EVAP control system pressure sensor. Open in the EVAP pressure sensor signal wire. Short to voltage in the EVAP pressure sensor signal wire. Bad ground at the EVAP pressure sensor. Water or corrosion in the EVAP pressure sensor connector.
What is the diagnostic trouble code for evaporative emission control?
P0453 is a diagnostic trouble code (DTC) for “Evaporative Emission Control Pressure Sensor High Input”.
What does p0453 mean on Ford fuel pump?
Basically P0453 Ford means the PCM (Powertrain Control Module) noticed the EVAP Pressure sensor or FTP is indicating a higher than normal pressure (above 4.5 Volts) in the EVAP system. NOTE: On some vehicles the FTP is a part of the fuel pump assembly in the tank.
