MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE> 13A-275 . CIRCUIT OPERATION • 5-volt voltage is applied to the fuel tank tempera- ture sensor output terminal (terminal No. 3) from • The fuel tank temperature sensor output voltage increases when the resistance increases and . TECHNICAL DESCRIPTION • The fuel tank temperature sensor converts the fuel tank temperature to a voltage. • The ECM detects the fuel tank temperature with this output voltage. . DESCRIPTIONS OF MONITOR METHODS Fuel tank temperature at engine start is higher than engine coolant temperature at engine start by . MONITOR EXECUTION Continuous . MONITOR EXECUTION CONDITIONS Other Monitor (There is no temporary DTC stored in memory for the item monitored below) • Not applicable Sensor (The sensor below is determined to be normal) • Engine coolant temperature sensor • Intake air temperature sensor .
