Disconnect transmission oil temperature sensor connector. Sensor is between pressure filter and cooler line connection. Connect jumper wire between harness connector terminals. If scan tool reads greater than 284°F (140°C), possible poor connection exists or sensor is faulty. Using ohmmeter, inspect sensor and compare readings with TEMPERATURE SENSOR SPECIFICATIONS table. If scan tool reads 284°F (140°C) or less, go to next step.TEMPERATURE SENSOR SPECIFICATIONS
