VEHICLE SPEED SENSOR







1. CHECK THE VOLTAGE BETWEEN TERMINALS.







1. Set the starter switch to "LOCK" and connect the signal check harness.
2. Start the engine.
3. Prepare the voltage measurement between VS (A27) and CGD (C3 and terminals of ECU connector (vehicle harness side).
4. Measure the voltage while the vehicle starts to run at the speed of km/h {6.2 miles/h}.

WARNING: Start the vehicle with caution to surroundings.

Standard: Pulse wave-shape by 8 V - 0 V

5 Stop the vehicle.












2. CHECK THE CONTINUITY BETWEEN TERMINALS.
1. Set the starter switch to "LOCK" and disconnect the connectors of ECU.
2. For vehicle equipped with AISIN automatic transmission.
a. Disconnect the connectors of vehicle speed sensor.
b. Measure the resistance between VS (A27) terminal of ECU connector (vehicle harness side) and SPSP terminal of vehicle speed sensor connectors (vehicle harness side).

Standard: Less than 1 ohm












3. Set the starter switch to "LOCK".
4. ECU connectors remain connected.
5. Measure the resistance between VS (A27) terminal of ECU connector (vehicle harness side) and ground.

Standard: infinite ohms
