Evaporative Emission Control System Pressure Sensor High Input

The fuel tank pressure sensor is reporting a voltage reading that is too high, usually due to a wiring open circuit, bad connector, or defective sensor. The engine needs this sensor to verify the fuel system is sealed and working properly, so a fault prevents accurate leak detection. Your vehicle may fail an emissions inspection and fuel odors could develop.
