STEP 6. Check connector C-90 at PCM for damage.
Q: Is the connector in good condition?

YES : Replace the PCM. Then go to Step 12.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 12.

STEP 7. Measure the ground voltage at manifold absolute
pressure sensor connector A-12 by backprobing.
(1) Do not disconnect the connector A-12.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 2 and ground by

backprobing.

• Voltage should be 0.5 volt or less.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage 0.5 volt or less?

YES : Go to Step 10.
NO : Go to Step 8.
