Honda HR-V: Gauges Symptom Troubleshooting - Outside Air Temperature Indicator Does Not
Change
Outside air temperature indicator does not change
NOTE: Outside air temperature is indicated based on the measurement value of
the outside air temperature
sensor located behind the center of the front bumper. Because of the location of
the sensor, it may be affected by
heat reflection from the road, engine and radiator heat, or hot exhaust from
surrounding traffic. To display the
outside air temperature, the gauge control module has an indication mode based
on engine coolant temperature
and vehicle speed. Some modes do not raise the temperature indication, so the
outside air temperature indication
may not change when the mode continues.
