speed sensor connector B-33.

(1) Disconnect the connector, and measure the 

voltage between terminal 2 and earth at the 
wiring harness side.

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

OK: 4.5 

 4.9 V

Q: Is the check result normal?

STEP 13. Measure the voltage at engine-A/T-ECU 
connector C-141.
(1) Disconnect output shaft speed sensor connector 

B-33.

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

(3) Measure the voltage between engine-A/T-ECU 

connector C-141 terminal No.73 and earth. 

OK: 4.5 

 4.9 V

Q: Is the check result normal?

YES : 

Go to Step 16.

NO : 

Go to Step 14.

STEP 14. Connector check: C-141 
engine-A/T-ECU connector

Check for the contact with terminals.

Q: Is the check result normal?

YES : 

Go to Step 15.

NO : 

Repair the defective connector.

STEP 17. Check the harness between output 
shaft speed sensor connector B-33 terminal No.2 
and engine-A/T-ECU connector C-141 terminal 
No.73.

Check the output line for open circuit.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the wiring harness.

STEP 18. Measure the output wave pattern of the 
output shaft speed sensor at engine-A/T-ECU 
connector C-141 (using an oscilloscope).
(1) Shift the selector lever to the D range.
(2) Accelerate the vehicle to approximately 50 km/h 

(shift range; 3rd.)

(3) Connect an oscilloscope, and measure the 

voltage between engine-A/T-ECU connector 
C-141 terminal No.73 and earth.

OK: A wave pattern such as the one 
shown on 

P.23A-139

 (Check Procedure 

Using an Oscilloscope) should be output, 
and the maximum value should be 4.8 V 
or more and the minimum value should 
be 0.8 V or less. There should be no noise 
in the output wave pattern.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Go to Step 19.
