MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-99
STEP 3. 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 4.
NO : Replace the throttle position sensor. (Refer to
, Throttle Body.) Then go to Step 9.
STEP 4. Check the maladjusted throttle position sensor.
Refer to, Throttle Position Sensor Adjustment (
Q: Is the output voltage normal?
YES : Go to Step 5.
NO : Adjust it. Then go to Step 9.
STEP 5. 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 6.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection (
). Then go to Step 9.

STEP 6. Check for harness damage 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 : Go to Step 7.
NO : Repair it. Then go to Step 9.
STEP 7. Check for harness damage between throttle
position sensor connector B-07 terminal 3 and ECM
connector C-62 terminal 78 <M/T> or PCM connector C-59
terminal 78 <A/T>.
Q: Is the harness wire in good condition?
YES : Go to Step 8.
NO : Repair it. Then go to Step 9.

STEP 8. Using scan tool MB991502, check data list item 14:
Throttle Position Sensor.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991502 to the data reading mode for item
14, Throttle Position Sensor.
•
With the throttle valve in the idle position, voltage should
be between 0.535 and 0.735 volts.
•
With the throttle valve in the full-open position, voltage
should be between 4.5 and 5.5 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points (
NO : Replace the ECM or PCM. Then go to Step 9.
STEP 9. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to
, Procedure 6
−
Other Monitor.
(2) Check the diagnostic trouble code (DTC).
Q: Is the DTC P0122 is output?
YES : Retry the troubleshooting.
NO : The inspection is complete.
