TROUBLESHOOTING

MULTIPOINT FUEL INJECTION (MPI)

13A-169

CAUTION

Short-circuiting the positive (+) probe between a 
connector terminal and earth could damage the 
vehicle wiring, the sensor, engine-ECU or all of 
them. Be careful to prevent this!

4. If voltmeter shows any division from standard 

value, check the corresponding sensor, actuator 
and related electrical wiring, then repair or 
replace.

5. After repair or replacement, recheck with the 

voltmeter to confirm that the repair has corrected 
the problem.
