STEP 6. Check connector B-04 at the manifold absolute 
pressure sensor and connector C-60 at ECM <M/T> or 
connector C-57 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Repair harness wire between manifold absolute 

pressure sensor connector B-102 (terminal No. 1) and 
ECM connector C-60 (terminal No. 73) <M/T> or PCM 
connector C-57 (terminal No. 91) <A/T> because of 
open circuit or harness damage. Then go to Step 12.

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

Connector Inspection 

P.00E-2

. Then go to Step 18.

STEP 7. Measure the sensor supply voltage at manifold 
absolute pressure sensor connector B-04 by backprobing.
(1) Do not disconnect the connector B-04.
(2) Turn the ignition switch to the "ON" position.

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

backprobing.

• 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 12.
NO :  Go to Step 8.

backprobing.
(1) Do not disconnect the connector C-60 <M/T> or connector 

C-54 <A/T>.

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