Vehicle Speed Sensor Check < M/T >

WARNING: This page is about a different car, the 2005 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

Remove the vehicle speed sensor and connect a 3 - 10 kiloohms resistor as shown in the illustration.
Turn the shaft of the vehicle speed sensor and check that there is voltage between terminals 2 - 3. (1 turn = 4 pulses)
If within the standard value, the vehicle speed sensor is OK. If not within the standard value, replace the vehicle speed sensor.
1. Standard value: 0 or Battery Voltage (1turn = 4pulses)
