The odemeter is controlled by the VSS which is on the engine block next to the oil filter. Check fuse #22 first. Then check wiring and/or replace sensor
VEHICLE SPEED SENSOR (VSS)
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.
Turn ignition on. Check for voltage between Green/White and Black/Yellow wires. See Fig. 12. If battery voltage exists, go to step 5). If battery voltage does not exist, go to next step.

With ignition on, check for battery voltage between Black/Yellow wire and ground. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Black/Yellow wire between speed sensor and underdash fuse box.
Check for continuity between Black wire and ground. If continuity is present, go to next step. If continuity is not present, repair open between vehicle speed sensor and Powertrain Control Module (PCM) ground. PCM ground is located next to throttle body.
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. If voltage does not pulse between zero and 5 volts, replace speed sensor.
