Vehicle Speed Sensor (VSS) Circuit: Odyssey

  1. Check for DTC P0720. Repair as necessary. If DTC P0720 does not exist, check No. 9 BACK-UP (10-amp) fuse. Fuse is located in driver's side underdash fuse/relay box. Using backprobe set, check for continuity between instrument cluster 22-pin connector "B" terminal No. 16 (Black wire) and ground connector G503. See WIRING DIAGRAMS article. Ground connector G503 is located at right side of dash, behind glove box, above keyless door lock control unit. If continuity exists, go to next step. If continuity does not exist, repair open in Black wire between instrument cluster 22-pin connector "B" and ground connector G503. See Figure.
  2. Raise and support front of vehicle. Disconnect instrument cluster 22-pin connector "B". Measure voltage between ground and instrument cluster 22-pin harness connector "B" terminal No. 2 (Blue/White wire). Turn ignition on and place transmission in Neutral. Block one front wheel. While observing voltmeter, rotate other front wheel more than 3 MPH. If voltage toggles between zero and about 5 volts or more, replace instrument cluster. If voltage does not toggle between zero and about 5 volts or more, go to next step.
  3. Using backprobe set, measure voltage between ground and PCM 32-pin connector "A" terminal No. 9 (Blue/White wire). See PIN VOLTAGE CHARTS article. Block one front wheel. While observing voltmeter, rotate other front wheel more than 3 MPH. If voltage toggles between zero and about 5 volts or more, repair Blue/White wire between PCM 32-pin connector "A" and instrument cluster 22-pin connector "B" terminal No. 2. If voltage does not toggle between zero volts and about 5 volts or more, go to next step.
  4. Disconnect PCM 32-pin connector "A". Check for continuity between ground and PCM 32-pin harness connector "A" terminal No. 9 (Blue/White wire). If continuity exists, repair short in Blue/White wire between PCM 32-pin connector "A" and instrument cluster, cruise control connector terminal No. 12 or driver's multiplex control unit 22-pin connector "B" terminal No. 14. If continuity does not exist, check for bent, loose or corroded terminals. If terminals are okay, substitute a known-good PCM and recheck. See SUBSTITUTING PCM in SELF-DIAGNOSTICS - INTRODUCTION article. If symptom or problem goes away, replace original PCM.
