Inspection

1.	Ignition "ON"

2.

Blow air with changing temperature to the in car sensor air inlet. Measure sensor resistance between 2 and 4 terminals. [Specification] Temperature [°C(°F)] Resistance between terminals 2and 4 (kΩ) -30 (-22) 509.57 -20 (-4) 285.61 -10 (14) 164.65 -5 (23) 126.38 0 (32) 97.71 5 (41) 76.09 10 (50) 59.67 15 (59) 47.13 20 (68) 37.48 25 (77) 30.00 30 (86) 24.17 35 (95) 19.57 40 (104) 15.98 50 (122) 10.81 In car sensor is negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the center facia panel(A).

3.	Disconnect the connector of in-car sensor (A).Loosen the mounting 2 screws and then remove the in-car sensor (B).

4.	Installation is the reverse order of removal.
