System Inspection

[1][2]FUEL TANK PRESSURE SENSOR
This is a sensor to detect fuel tank leakage it measures the differential pressure between inside and outside fuel tank.
The [1][2]fuel tank pressure sensor is a pressure sensitive variable resistor. It measures the change of pressure in the fuel tank and monitors leakage detection. It is used to close the evaporative system and observes tank pressure respectively with canister close valve.
