MULTIPORT FUEL INJECTION(MFI) DIAGNOSIS
MULTIPORT FUEL INJECTION (MFI) <2.4L>
STEP 13. Check the sensor power supply line for short
(2) Check for the continuity between terminal 46 and ground.
There should be 2 ohms or more.
Q: Does the multi-meter reading exceed the specified
STEP 14. Check the sensor power supply lines.
flow through the harness PCM connector (terminal 46).
Q: Is there any failure in the sensor power supply lines?
When a failure is found : Repair if necessary. (Refer to
GROUP 90, Circuit Diagrams
MFI System <2.4L
STEP 15. Check the ground circuit voltage at PCM
Voltage should be 0.5 volts or less.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the multi-meter reading below the specified value?
YES : Check connectors D-15, C-71, C-17, C-40 and repair
or replace as required. Refer to GROUP 00E,
. If connectors
D-15, C-71, C-17, C-40 are in good condition, check
NO : Go to Step 16.
