DTC 33 Vehicle Speed Sensor 2:

Vehicle Speed Sensor 2 Circuit:

1. MEASURE SIGNAL VOLTAGE INPUT OF TCU.
a. Turn ignition switch ON (with engine OFF).
b. Move select lever to "N" and slowly move vehicle by pushing it.
c. While vehicle is slowly moving, measure signal volt. age input of TCU.

Connector & Terminal/Specified value
(B66) No. 11 - (B66) No.20/0 or 5V

2. CHECK HARNESS/CONNECTOR BETWEEN TCU AND VEHICLE SPEED SENSOR 2.
a. Disconnect connector from TCU.
b. Disconnect connector from vehicle speed sensor 2.
c. Measure resistance between TCU connector and vehicle speed sensor 2 connector, and vehicle speed sensor 2 connector and body.


Connector & Terminal/Specified value
(B66) No. 11 - (B9) No. 1/0 ohms
(B66) No. 11 - Body /1 Mohms min.
(B9) No.2 - Body/0 ohms

3. CHECK VOLTAGE OF POWER SUPPLY LINE.
a. Turn ignition switch ON (with engine OFF).
b. Measure voltage between vehicle speed sensor 2 connector and body.

Connector & Terminal/Specified value
(B9) No. 3 - Body / 10V, min.

VSS 2 Terminals:

4. CHECK VEHICLE SPEED SENSOR 2.
a. Remove vehicle speed sensor 2 from transmission, connect body harness connector (B9) to vehicle speed sensor 2 and turn ignition switch ON.
b. Rotate vehicle speed sensor 2.
c. Check that voltage across vehicle speed sensor 2's connector terminals change (from 0 to 5) volts four times per rotation.

Connector & Terminal/Specified value
(B9) No. 1 - (B9) No. 2 / 0 to 5 V
