Passenger Compartment Temperature Sensor Inspection (Auto A/C)

WARNING: This page is about a different car, the 2014 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Measure the temperature around the passenger compartment temperature sensor and measure the resistance between passenger compartment temperature sensor terminals A and B.
- If the characteristics of the passenger compartment temperature sensor are not as shown in the graph, replace the passenger compartment temperature sensor.
