P0452 2015 GMC Sierra Code - Fuel Tank Pressure Sensor Circuit Low Voltage
Quick Answer
The fuel tank pressure sensor measures vapor pressure or vacuum in the Evaporative Emission (EVAP) system. Common causes include Faulty Fuel Tank Pressure (FTP) Sensor, Fuel Tank Pressure Sensor harness is open or shorted, Fuel Tank Pressure Sensor circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
