P054 is not a valid code for this vehicle. Can you double-check this code for me?
Ok, great. And which EVAP Sensor did you have replaced?
Ok... which sensor? There are dozens of sensors in the EVAP System. Do you know the location of the sensor that was replaced? Or the name?
Ok. The P0545 is a fairly straight forward code that points to a problem with the Fuel Tank Pressure Sensor. This sensor is located at the top of the fuel tank, mounted to the Fuel Pump Assembly. To gain the proper access, the fuel tank will need to be removed from the vehicle. Carefully inspect the electrical connector and wire harness for any loose, broken or damaged wires (inspect carefully, rubbed-through wires are common here!). If the wire harness checks ok, make sure the EVAP Canister is not clogged, and there are no problems in the lines from the canister like clogs, cracks or holes. If the visual inspections check ok, replacing the Fuel Tank Pressure Sensor should solve this problem.
