Rookie
I just had a new fuel pump/float module installed in the fuel tank. Now I am getting DTC code P0453. Listed as "fuel tank pressure sensor circuit high input".
So before I take it back to the garage that installed it. I need to know if this device is part of that assembly?
Any other sugestions would be greatly appreciated. Thanks.

MasterPressure sensor sits right on top of the fuel pump/float level assembly. Needs to be removed to replace the fuel pump.
