STEP 10. Measure the signal voltage at PCM connector D-
134 by backprobing.
(1) Do not disconnect PCM connector D-134.
(2) Turn the ignition switch to the "ON" position.
(3) Remove the fuel cap.

(4) Measure the voltage between PCM connector D-134 

terminal 82 and ground by backprobing.

• The voltage should measure between 2.0 and 3.0 volts.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 2.0 and 3.0 volts?

YES : Go to Step 14.
NO :  Go to Step 11.

STEP 11. Check PCM connector D-134 for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 12.
NO :  Repair or replace the faulty component. (Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-

2

). Go to Step 15.

STEP 12. Check intermediate connectors D-112, E-111 and 
F-07, and fuel tank differential pressure sensor connector 
G-05 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 13.
NO :  Repair or replace the faulty component. (Refer to

STEP 13. Check the harness wires between PCM 
connector D-134 terminal 82 and fuel tank differential 
pressure sensor connector G-05 terminal 1 for damage. 
Q: Are the harness wires in good condition?

YES : It can be assumed that this malfunction is intermittent. 

(Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points 

− How to Cope with 

Intermittent Malfunction 

P.00-6

). Go to Step 15.
