2.
Blow air with changing temperature to the in car sensor air inlet. Measure sensor resistance between 2 and 4 terminals.
Specification
Temperature [℃(℉)] | Resistance between terminals 2and 4 (㏀) |
60(140) | 7.463 ± 2.6% |
50(122) | 10.810 ± 2.2% |
35(95) | 19.59 ± 1.6% |
25(77) | 30.00 ± 1.2% |
15(59) | 47.130 ± 1.7% |
0(32) | 97.710 ± 2.4% |
-15(5) | 216.1 ± 3.2% |
-30(-22) | 50936 ± 4.1% |
note
In car sensor is negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.
