Hello and welcome to Just answer,


Are you needing information for the fuel tank pressure sensoror the fuel pressure regulator?

Customer: replied 7 years ago.
Fuel pressure sensor
Expert:  Scott K replied 7 years ago.

There is no sensor to monitor fuel pressure, there is a fuel tank pressure sensor which is part of the evaporative emissions system which is mounted on top of the fuel tank, it measures the pressure in the tank. The fuel line pressure is regulated by a vacuum regulator but has no electrical sensor to send line pressure information to the control module.


Is there a specific problem you are having? can you explain your situation a little more?

the service engine soon light is on. When I check the code it says ftp sensor high voltage. I have bought the replacement but don't know where it goes.

FTP= Fuel Tank Pressure sensor.


It goes on top of the fuel tank pump module, the sensor is #1 in the diagram below. In order to replace it the fuel tank has to removed.
