Test D22 - Speed Sensor Test

  1. Turn ignition on. Ensure speedometer displays all segments. If not, replace speedometer/odometer module. If all segments are displayed, drive vehicle and ensure odometer, tripminder and cruise control operate. Unplug speed sensor.
  2. Using an ohmmeter, measure resistance between 2 wires at speed sensor connector. If resistance is less than 500 ohms, repair or replace Dark Green/White wire between speed sensor and pin No. 3 on 60-pin connector.
  3. If resistance is 500 ohms or more, check resistance between speed sensor terminals. If resistance is not 200-230 ohms, replace speed sensor. If resistance is 200-230 ohms, check driven gear and retainer.
  4. If okay, check drive gear, inside transmission. If drive gear is okay, check wiring to instrument cluster. If no problem can be found, replace PRC module.
