MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L> 13B-675 . CIRCUIT OPERATION • A 5-volt voltage is supplied to the power terminal of the fuel tank differential pressure sensor (ter- • A voltage proportional to the pressure in the fuel tank is sent from the output terminal of the fuel . TECHNICAL DESCRIPTION • To judge if the fuel tank differential pressure sen- sor is defective, the ECM <M/T> or PCM <A/T> • Based on the test conditions and judgment crite- ria, the ECM <M/T> or PCM <A/T> judges if the . DESCRIPTIONS OF MONITOR METHODS • Detect malfunction if change of fuel tank differen- tial pressure sensor output voltage during idling . MONITOR EXECUTION • Continuous. .
