MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-91
STEP 4. Check connector C-58 at ECM <M/T> or connector
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection (
). Then go to Step 14.
STEP 5. Check for open circuit and short circuit to ground
between throttle position sensor connector B-07 terminal 4
and ECM connector C-58 terminal 42 <M/T> or PCM
connector C-55 terminal 46 <A/T>.
Q: Is the harness wire in good condition?
YES : Replace the ECM or PCM. Then go to Step 14.
NO : Repair it. Then go to Step 14.
STEP 6. Check the continuity at throttle position sensor
harness side connector B-07.
(1) Disconnect the connector B-07 and measure at the harness
side.
(2) Measure the continuity between terminal 1 and ground.
•
Should be less than 2 ohm.
Q: Is the continuity normal?
YES : Go to Step 9.
NO : Go to Step 7.

STEP 7. Check connector C-58 at ECM <M/T> or connector
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection (
). Then go to Step 14.
STEP 8. Check for open circuit and harness damage
between throttle position sensor connector B-07 terminal 1
and ECM connector C-58 terminal 49 <M/T> or PCM
connector C-55 terminal 57 <A/T>.
Q: Is the harness wire in good condition?
YES : Replace the ECM or PCM. Then go to Step 14.
NO : Repair it. Then go to Step 14.

STEP 9. Check the throttle position sensor.
(1) Disconnect the connector B-07.
(2) Measure the resistance between throttle position sensor
side connector terminal 1 and 4.
Standard value: 3.5
−
6.5 k
Ω
(3) Measure resistance between the throttle position sensor
side connector terminal 1 and 3.
(4) Move the throttle valve from the idle position to the full-open
position.
•
Resistance should change smoothly in proportion to the
opening angle of the throttle valve.
Q: Is the resistance normal?
YES : Go to Step 10.
NO : Replace the throttle position sensor.(Refer to
, Throttle Body.) Then go to Step 14.
STEP 10. Check connector C-58, C-62 at ECM <M/T> or
connector C-55, C-59 at PCM <A/T> for damage.
Q: Is the connector in good condition?
YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection (
). Then go to Step 14.

between throttle position sensor connector B-07 terminal 3
and ECM connector C-62 terminal 78 <M/T> or PCM
connector C-69 terminal 78 <A/T>.
Q: Is the harness wire in good condition?
YES : Go to Step 12.
NO : Repair it. Then go to Step 14.
STEP 12. Check for short circuit to ground between
throttle position sensor connector and auto-cruise control-
ECU.
