Outside temperature is blank. How do I fix sensor?

Did you by chance check for DTC'S diagnostic trouble codes?

Instrument Cluster Diagnostic Trouble Code (DTC) Index DTC Description Source Action B1255 Air Temperature External Sensor Circuit Open Instrument cluster Go To Pinpoint Test E .

The outside temp sensor is located behind your front grille. Try to look for a 2-wire small sensor. You will need to remove the grille to gain smooth access and to test it. Use multimeter to measure sensor resistance when disconnected. Depending on actual air temperatures, sensor should measure 1.27 kilohms when at 104degF, and 16.5kilohms when at -4degF. The rest of the normal values should be in between these kilohms and temperature ranges.

Remove all batteries from outdoor sensor and weather station.

Press one of the buttons on the weather station at least 20 times to clear all memory.

Verify that the weather station is blank before proceeding (there may be lines painted on
the screen that will show when power is removed).

Leave both units without power for 15 minutes (very important).

Insert fresh batteries into the clock.

Insert fresh batteries into the outdoor sensor.

Press the TX button on the outdoor sensor to transmit RF signal.

Keep the outdoor sensor 5-10 feet from the forecast station.

When RF connection is established, the temperature will appear on the station. Allow the
outdoor sensor and weather station to sit together for 15 minutes to establish a strong
connection.

Have you changed the batteries in the outdoor temperature sensor?

after calibrate sensor display numeral are blank

I also have the same problem, I would also be happy with a diagram of the location of the sensor.

you need to replace the ambient temperature sensor or do the math
