Where is AC temperature sensor?
The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.
What happens when you reset the ECU on a Honda?
After you install aftermarket parts, resetting the ECU will help your car’s computer “learn” and accommodate the new parts. Sometimes a faulty check engine light may appear, so resetting the ECU can make it go away.

The ECM plays a crucial role in newer vehicles, where many (if not all) of the essential functions of the car are controlled by the ECM.
What’s the normal temp for a Honda CRV?
Just as a point of reference, our ’06 2.4L engine’s temp gauge starts to climb when the coolant temp reaches 140F. It is in the NORMAL position at 170F. The gauge stays in the normal position while driving, winter & summer, even as the temps range from 183F. (when the thermostat opens fully) to 205F.
When does the thermostat go back up on a Honda CRV?
Coming out of my heated garage at 46* into -8* weather, it takes about 35 minutes of driving before the temp is a 1/4 way up the scale. During the drive I have noticed that once the gauge reads about 1/4 of the way up you will see the thermostat open and the temp will drop back down to C and slowly start coming back up.
