Ignition "ON"
Blow air with changing temperature to the in car sensor air inlet. Measure sensor resistance between 2 and 4 terminals
Temperature [℃(℉)] | Resistance between terminals 2and 4 (㏀) |
-20(-4) | 290.21 |
-10(14) | 165.6 |
0 (32) | 97.83 |
10(50) | 59.67 |
20(68) | 37.48 |
30(86) | 24.17 |
40(104) | 115.98 |
50(122) | 10.81 |
In car sensor is negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.
Disconnect the negative (-) battery terminal.
Remove the center facia lower panel(A) then disconnect the connector (B).
Disconnect the connector of in-car sensor (A).Loosen the mounting 2 screws and then remove the in-car sensor.
Installation is the reverse order of removal.
