Hi,

My check engine light decided that it would make an appearance this morning so I hooked up a code reader and got the following DTC:

"P0453- Evap System Pressure Sensor: Signal too high."

I was hoping someone could help me make some sense of what this could be pointing at and how to remedy the situation. Im not sure but I thought it might have something to do with the fuel system?? Just a bit of background...I filled the car up with fuel the other night and drove a few miles home and parked the car. 2 or 3 days have gone by with the car sitting in the garage when I decided that I would take it out for a spin today and then noticed that the light had come on. I did remove the gas cap and then replaced it but the light was still on after I restarted the car....Im not too sure if it would have reset itself after doing that if that were actually the problem or not.

Anyhow, I did manage to grab the code and reset the CEL but in the mean time I would like to try and figure out the situation and hope that light doesnt make an encore appearance.
