1. Measure the temperature around the ambient temperature sensor and measure the resistance between the ambient temperature sensor terminal.

If the characteristics of the ambient temperature sensor are not as shown in the graph, replace the ambient temperature sensor.
Ambient Temperature Sensor Inspection [Full Auto Air Conditioner]
Ambient Temperature Sensor Removal/Installation [Full Auto Air Conditioner]Electronic Control System Outline [Fw6 A EL, Fw6 Ax EL]
Outline
In the electronic control system, the TCM calculates the control content
based on signals from each type of sensor and switch to operate output parts
such as each solenoid. In consideration of suppressed shift shock, smooth driving,
and improved fuel economy, the TCM performs ...
