P0453 Evaporative Emissions Control System Pressure Sensor High Input

[Chip3130]

I got the check engline light from this code a couple months ago, and I keep resetting the light, but it keeps returning.

Any advice on what I should do? There's really no symptoms that I can tell you. The light is annoying.

That's the fuel tank vent/test system. There won't be any symptoms. Sounds like it's probably the sensor or the wiring, instead of a leak. You'll have to fix it if you want the light to stay off.

Had a similar problem on my old 2001 GMC Jimmy 4X4,
was a sensor inside a black box at the fuel tank near the fill neck.
