Repair Procedures: Inspection

Blow air with changing temperature to the in car sensor air inlet. Measure sensor resistance between 2 and 4 terminals.

RESISTANCE SPECIFICATION

Temperature [°C(°F)]	Resistance between terminals 2 and 4 (kΩ)
-20(-4)	285.61
-10 (14)	164.65
0 (32)	97.71
10 (50)	59.67
20(68)	37.48
30(86)	24.17
40(104)	15.98
50(122)	10.81

NOTE: In car sensor is negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.
