What does the p0453 fuel tank pressure sensor mean?
It uses this sensor, also known as a fuel tank pressure (FTP) sensor to check for leaks. Basically P0453 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.
How does the fuel tank pressure sensor work?
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. It uses this sensor, also known as a fuel tank pressure (FTP) sensor to check for leaks.
Where is the pressure sensor high input on a 1998 Ford Windstar Van?
We put a new fuel pump in our 1998 Ford Windstar van and now we are having a stalling problem. The showed p0453 for the problem, which is called the pressure sensor high input. Where is this located on the van??? We have been having problems with a strong smell of gas on occasion also.
What should the pressure be on the FTP sensor?
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). It shouldn’t ever be above 4.5 Volts. 1) If it is close to 2.7V with the gas cap off, the problem is likely intermittent.

Why is there a pressure sensor on my fuel tank?
There are a few important reasons: The fuel tank pressure sensor does all this by monitoring the pressure, both positive and negative, inside your fuel tank. This sensor is an integral part of your car’s evaporative emissions system, also known as EVAP.
