Vehicle Speed Sensor: Legend
- Verify fuse No. 22 in underdash fuse block is okay. Speed sensor is located next to oil filter. Unplug 3-pin connector from speed sensor.
- Using an ohmmeter, check for continuity between Green/White wire and ground. See Fig 1 . If continuity exists, go to next step. If continuity does not exist, repair open between speed sensor and ECU ground. ECU ground is located next to throttle body.
- With ignition on, measure voltage between Black/Yellow wire and ground. If battery voltage is present, go to next step. If battery voltage is not present, repair open in Black/Yellow wire between speed sensor and underdash fuse box.
- Measure voltage between Yellow/Red wire and ground. If voltage is about 5 volts, go to next step. If voltage is not about 5 volts, repair short to ground in Yellow/Red wire.
- Reconnect wiring to speed sensor. Raise and support vehicle. Connect voltmeter between sensor connector Yellow/Red wire and ground. With ignition on and transaxle in Neutral, block one front wheel and slowly rotate other front wheel. Voltage should pulse between zero and 5 volts. If voltage does not pulse between zero and 5 volts, replace speed sensor.
