Turn the ignition switch OFF.
Disconnect ambient temperature sensor.
Check the resistance of ambient temperature sensor between terminal “+” and “-” whether it is changed by changing of the ambient temperature.
Ambient temperature [℃(℉)] | Resistance [㏀] | Voltage [V] |
-30(-22) | 507 | 4.720 |
-20(-4) | 284.5 | 4.522 |
-10(14) | 164.2 | 4.225 |
0 (32) | 97.5 | 3.821 |
10 (50) | 59.6 | 3.322 |
20 (68) | 37.46 | 2.772 |
30(86) | 24.18 | 2.227 |
40(104) | 16 | 1.735 |
50(122) | 10.83 | 1.323 |
If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.
If the problem is corrected, replace the ambient temperature sensor.
Disconnect the negative (-) battery terminal.
Remove the engine room RH side under cover.
(Refer to EM group - “Engine and Transaxle Assembly”)
Disconnect the ambient temperature sensor connector (A).
Remove the ambient temperature sensor (B).
Installation is the reverse order of removal.
