STEP 9. Check connector B-14 at the barometric pressure
sensor and connector C-60 at ECM <M/T> or connector
C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between barometric pressure

sensor connector B-14 (terminal No. 1) and ECM
connector C-60 (terminal No. 81) <M/T> or PCM
connector C-54 (terminal No. 46) <A/T> because of
open circuit or harness damage. Then go to Step 18.

NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 18.

STEP 11. Check for short circuit to ground between
barometric pressure sensor connector B-14 (terminal No.
1) and ECM connector C-60 (terminal No. 81) <M/T> or PCM
connector C-54 (terminal No. 46) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 18.
NO : Repair it. Then go to Step 18.

STEP 12. Measure the ground voltage at barometric
pressure sensor connector B-14 by backprobing.
(1) Do not disconnect the connector B-14.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal No. 5 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 15.
NO : Go to Step 13.
