Swift L4-1298cc 1.3L DOHC 3 MFI 16V (1989)
Vehicle Speed Sensor: Testing and Inspection
1. Turn OFF ignition switch.
2. Disconnect coupler(s) from transmission control module.
3. Bring ohmmeter probes in touch with coupler terminals from harness side.
Separately from the above inspection, vehicle speed sensor can be checked on its resistance by disconnecting the coupler.
NOTE:
-
Function of vehicle speed sensor can be checked by measuring generated pulse as voltage.
-
For its measurement, use an analog type voltmeter while spinning wheels on lift and with selector lever in "D" position.
