Speedometer Head: Testing and Inspection
INSPECTION
1. INSPECT SPEEDOMETER ON-VEHICLE
Using a speedometer tester, check the speedometer for indication error and check operation of the odometer.
HINT: Tire wear and tire over or under inflation will increase the indication error.
It the error is excessive, replace the speedometer.
2. 5VZ-FE (M/T only): INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal 1 and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from the tester to terminal 3 and the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that the voltage between terminals 2 and 3 changes from approximately 0 V to 11 V or more.
HINT: The voltage change should be checked 4 times during each revolution of the speed sensor shaft.
If the result is not as specified, replace the sensor.
