Code 10 - Low Speed Sensor Resistance

  1. Turn ignition off. Disconnect diagnostic connector (Black/Orange wire) from its mating half (Red wire). Reconnect diagnostic connector. Turn ignition on. If Yellow RABS warning light illuminates, go to next step. If warning light does not illuminate, go to INTERMITTENT DIAGNOSIS  for all affected circuits.
  2. Turn ignition off. Disconnect negative battery cable. Disconnect control module connector. See COMPONENT LOCATIONS  . Gently pull on terminals No. 3 (Light Green/Black wire) and No. 10 (Red/Pink wire) of control module and control module harness connector. See Figure .
  3. If connector terminals are clean, fully engaged and corresponding terminal of control module are okay, leave control module disconnected and go to next step. If terminals are loose or have pulled out of connector, repair or replace terminals or connector as necessary and go to step 9). If control module terminals are loose, bent, deformed, corroded or missing, replace control module and then go to step 9).
  4. Ensure ignition is off. Disconnect and inspect 2-pin speed sensor connector. Gently pull on both terminals of speed sensor harness connector. If terminals are clean and fully engaged in connector, leave sensor disconnected and go to next step. If terminals are loose or have pulled out of connector, repair or replace terminals or connector as necessary and go to step 9). If speed sensor terminals are loose, bent, deformed, corroded or missing, replace speed sensor. Reconnect sensor connector and go to step 9).
  5. Check resistance between terminals No. 3 (Light Green/Black wire) and No. 10 (Red/Pink wire) of control module harness connector. If resistance is greater than 20,000 ohms, go to next step. If resistance is 20,000 ohms or less, repair short between Light Green/Black and Red/Pink wires. After repairs, go to step 9).
  6. Check resistance between terminal No. 10 (Red/Pink wire) of control module harness connector and ground. If resistance is greater than 20,000 ohms, go to next step. If resistance is 20,000 ohms or less, repair short in Red/Pink wire. After repairs, go to step 9).
  7. Check resistance between speed sensor terminals. If resistance is 900-2500 ohms, go to next step. Replace control module and go to step 9).
  8. Ensure all preceding diagnostic steps have been completed and that involved wiring integrity has been verified. If steps have not been completed, go to last diagnostic step completed and continue from there. If all diagnostic steps have been completed, replace control module and go to next step. If control module has already been replaced with no resolution of problem, replace speed sensor and go to next step.
  9. Ensure ignition is off. Reconnect negative battery cable. Ensure all connectors are connected and secure. Retrieve trouble codes. See RETRIEVING TROUBLE CODES  . If Code 16 is present, go to CODE 16 under TEST DRIVE  . If Code 10 is present, go to next step. If any other trouble code is present, go to corresponding test for appropriate trouble code.
  10. Ensure all preceding diagnostic steps have been completed and that involved wiring integrity has been verified. If steps have not been completed, go to last diagnostic step completed and continue from there. If all diagnostic steps have been completed, go to next step.
  11. If previous diagnostic steps have been completed, problem is most likely wiring related. Go to INTERMITTENT DIAGNOSIS  and perform tests on all affected circuits. If problem is not resolved, repeat step  8 . If problem is resolved, repair is complete. Go to CODE 16 under TEST DRIVE  .
