DTC P0451: EVAP Emission Control System Pressure Sensor Range/Performance Problem: DTC Detecting Condition
- DTC Description, the ECM monitors pressure in the fuel tank by means of Fuel Tank Pressure Sensor (FTPS) during purge control valve opening or closing phase. This monitoring will determine if pressure sensor signal is stuck. The ECM sets DTC P0451 if pressure variation is smaller than the predetermined threshold.
If same error code is set in the next driving cycle, the ECM illuminates the MIL.
