Blow air with changing temperature into the in-car sensor air inlet. Measure the sensor resistance between 1 and 2 terminals.
Specification
Temperature [°C(°F)] | Resistance between terminals 1 and 2 (㏀) |
-30(-22) | 509.6 |
-15(5) | 216.0 |
0 (32) | 97.71 |
15(59) | 47.13 |
25(77) | 30.00 |
35(95) | 19.59 |
50(122) | 10.81 |
60(140) | 7.463 |
note
An in-car sensor is a negative type thermistor. The resistance will rise with lower temperature, and reduce with higher temperature.
