STEP 5. Check for open circuit and short circuit to ground
between manifold differential pressure sensor connector
B-28 (terminal No. 3) and PCM connector D-135 (terminal
No. 97).
Q: Is the harness wire in good condition?

YES : Replace the PCM. Then go to Step 12.
NO : Repair it. Then go to Step 12.

STEP 6. Check the continuity at manifold differential
pressure sensor harness side connector B-28.
(1) Disconnect the connector B-28 and measure at the harness

side.

(2) Measure the continuity between terminal No. 2 and ground.

• Should be less than 2 ohms.

Q: Is the continuity normal?

YES : Go to Step 9.
NO : Go to Step 7.

STEP 7. Check harness connector D-135 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 12.
