TSB Revision
MULTIPORT FUEL INJECTION (MFI) <2.4L>
13A-621
STEP 11. Measure the sensor supply voltage at vehicle
speed sensor harness side connector B-39.
(1) Disconnect the vehicle speed sensor connector B-39 and
measure at the harness side.
(2) Disconnect the combination meter connector and
auto-cruise control-ECU connector.
(3) Turn the ignition switch to the "ON" position.
(4) Measure the voltage between terminal No. 3 and ground.
• Voltage should be between 4.8 and 5.2 volts.
(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.8 and 5.2 volts?
YES : Go to Step 12.
NO : Check connector B-36 at intermediate connector for
damage, and repair or replace as required. Refer to
GROUP 00E, Harness Connector Inspection
. If intermediate connector is in good
condition, repair harness wire between vehicle speed
sensor connector B-39 (terminal No. 3) and ECM
connector C-60 (terminal No. 86) because of short
circuit to ground or harness damage. Then go to Step
17.
STEP 12. Check the vehicle speed sensor.
Refer to GROUP 54A, Combination Metre
− Inspection − Vehi-
cle Speed Sensor Check
Q: Is the vehicle speed sensor normal?
YES : Go to Step 13.
NO : Replace the vehicle speed sensor. Then go to Step
17.
STEP 13. Check connector C-60 at ECM for damage.
Q: Is the connector in good condition?
YES : Go to Step 14.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 17.
