Answer 1

HI there,

This code is for the evap system pressure sensor. The problem with this code is it's usually not a problem with the sensor, but some other part of the system. If some other part isn't working properly the pressure won't change and this code will appear. The system should be smoke tested to try and locate a leak and the vent control and purge control valves should be tested as well.
