Oil Temperature Sensor

  1. Ensure ignition switch is off. Connect measuring unit to TCM. See Figure. Using a DVOM, measure resistance between measuring unit terminals No. 14 and 15. If resistance is as specified in the OIL TEMPERATURE SENSOR RESISTANCE table below, sensor and wiring are okay. If resistance is not as specified, go to next step.
  2. Disconnect transaxle 26-pin connector. See Figure. Connect DVOM leads to 26-pin connector terminals No. 12 and 13. See Figure. Measure resistance between 26-pin connector terminals (oil temperature sensor terminals) as transaxle fluid temperature gradually increases. See OIL TEMPERATURE SENSOR RESISTANCE table below. If resistance is not as specified, replace oil temperature sensor.
