(b) Measure the resistance between terminals 1 and 2 of the ambient temperature sensor connector at each temperature. Standard resistance: 1.6 to 1.8 kΩ at 25 °C (77°F) 0.5 to 0.7 kΩ at 40 °C (104°F) HINT: As the temperature increases, the resistance decreases. NOTICE: When installing the ambient temperature sensor, be sure to connect the sensor connector before connecting the battery. REPLACE AMBIENT TEMPERATURE NG SENSOR OK 3.
