How can i fix this problem

Answer 1

Hi there,

This code is for the fuel tank pressure sensor. This is mounted in the top of the fuel tank. Normally this code can be brought up by another faulty part not working. The sensor is used by the computer to check for leaks in the evap system. If not pressure can build because of leaks, then the code will be triggered. A common cause is the vent control valve.
