Trouble code P0452 means: Evaporative emission control system,pressure sensor low input
Trouble code P0452 means: Evaporative Emission System Pressure Sensor/Switch Low Input Trouble code P0453 means: Evaporative Emission System Pressure Sensor/Switch High Input
Trouble code P0451 means: Evaporative emission control system,pressure sensor range or performance problem
Trouble code P0454 means: Evaporative Emission System Pressure Sensor/Switch Intermittent
Could be a faulty pressure sensor. The pressure sensor on many GM vehicles is located on top of the fuel tank attached to the fuel pump/sending unit assembly. It can be changed with the tank in place if you can get your fingers on it. Unplug the wire harness from it and wiggle the sensor straight up and out.
