Vehicle Speed Sensor

Check for blown fuse No. 1 (10-amp) in dash fuse/relay box (located at left kick panel). Disconnect VSS 3-pin connector. Connect Test Harness (07LAJ-PT3020A) to engine wiring harness. Connect Red clip of test harness to positive lead of voltmeter. Using ohmmeter, check for continuity between Red clip of test harness clip and ground. If continuity exists, go to next step. If continuity does not exist, repair open in Black wire.
Connect other test harness connector to VSS. Connect White clip of test harness to positive lead of voltmeter, and Red clip of test harness to negative lead of voltmeter. Turn ignition on. If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Yellow wire between VSS and dash fuse/relay box.
Connect Green clip of test harness to positive lead of voltmeter, and Red clip of test harness to negative lead of voltmeter. Turn ignition on. If 5 volts or more exists, go to next step. If less than 5 volts exists, repair open in Orange wire between VSS, Powertrain Control Module (PCM), Transmission Control Module (TCM) and cruise control unit.
Turn ignition off. Raise and support front of vehicle. Turn ignition on, and shift transaxle into Neutral. Block one wheel, and slowly rotate other wheel. If voltage pulses from zero and 5 or more volts, go to next step. If voltage does not pulse as specified, replace VSS.
Disconnect speedometer connector. Block one wheel, and slowly rotate other wheel. Using voltmeter, check voltage between speedometer connector Orange wire and ground. If voltage pulses, replace speedometer. If voltage does not pulse, repair open in Orange wire between VSS and speedometer.
