Outside Air Temperature Indicator Test
2008 Acura TSX L4-2.4LSECTION Outside Air Temperature Indicator Test
Outside Air Temperature Indicator Test
NOTE: To test the outside air temperature sensor, refer to Heating and Air Conditioning.
Troubleshooting
If the indicator displays "---------" for more than two seconds after selecting the outside air temperature display mode, Check the climate control system for DTCs, or an open in the LT BLU wire between the under-dash fuse/relay box and the climate control unit.
Calibration
('06-08 models)
1. Unlock the driver's door by using the keyless transmitter.
2. Turn the ignition switch ON (II).
3. Press and hold the INFO switch for more than 3 seconds.
4. Select "CHANGE SETTING" on the multi-information display (MID).
5. Select "METER SETUP", and then "ADJUST OUTSIDE TEMP, DISPLAY".
6. Press the INFO switch repeatedly. When the desired correction value is shown on the MID, press the SEL/RESET switch.
7. The correction value is displayed for several seconds, and then the display goes back to "CUSTOMIZE MENU".
Example: Incorrect value = 68 °F (20 °C)
Desired correction value = +2 °F (+1 °C)
Correct value = 70 °F (21 °C)
Desired correction value = -2 °F (-1 °C)
Correct value = 66 °F (19 °C)
NOTE: To recalibrate the display to the true temperature, remove the outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
