To run the sensor input display mode, follow these steps

WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

Make sure the ignition switch is in LOCK (0), or the vehicle ignition is in the OFF mode
Press and hold both the passenger's AUTO and RECIRCULATION CONTROL buttons, then start the engine
After the engine starts, release both buttons The display panel control unit flashes the sensor number, then the value for that sensor Record the value displayed

To advance to the next sensor, press the REAR WINDOW DEFOGGER button

NOTE:

The sensor values are displayed in degrees Celsius (°C) or an alphanumeric code Use the charts to convert degrees Fahrenheit (°F), or convert the alphanumeric code to a numerical value
If the sensor value displays "Er" this indicates there is an open or short in the circuit or sensor Check for DTCs using the HDS, or use the climate control unit self-diagnostic function
If necessary, compare the sensor input display to a known-good vehicle under the same test conditions
If the sensor is out of the normal range, refer to the sensor test or substitute a known-good sensor, and recheck
