Ignition "OFF".
Remove the in car sensor connector.
Blow air with changing temperature to the in car sensor air inlet. Measure sensor resistance between 2 and 4 terminals.
In car sensor is negative type thermistor that resistance will rise with lower temperature, and reduce with higher temperature.
Temperature [℃(℉)] | Resistance between terminals 2and 4 (㏀) |
50 (122) 35 (95) 25 (77) 15 (59) 0 (32) -15 (-74.2) | 10.81 ± 2.2% 19.57 ± 1.6% 30.00 ± 1.20% 47.13 ± 1.7% 97.71 ± 2.4% 216.1 ± 3.2% |
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 panel. (Refer to BD group).
Loosen the mounting 2 screws and then remove the in-car sensor (B).
Installation is the reverse order of removal.
