DIAGNOSTIC TROUBLE CODE PROCEDURES

13Ac-13

STEP 6. Measure the sensor supply voltage at volume
airflow sensor harness side connector B-48.
(1) Disconnect the connector B-48 and measure at the harness

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 3 and ground.

• Voltage should be between 4.8 and 5.2 volts.

(4) 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 9.
NO : Go to Step 7.

STEP 7. Check connector D-134 at PCM for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 13.

STEP 8. Check for short circuit to ground between volume
airflow sensor connector B-48 (terminal No. 3) and PCM
connector D-134 (terminal No. 63).
Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 13.
NO : Repair it. Then go to Step 13.

STEP 9. Check the continuity at volume airflow sensor
harness side connector B-48.
(1) Disconnect the connector B-48 and measure at the harness

side.

(2) Check for the continuity between terminal No. 5 and

ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Go to Step 12.
NO : Go to Step 10.

STEP 10. Check connector D-134 at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness
