EQC Outside Temperature Sensor Issue

Yes, I've seen this on an EQC. Often the sensor itself fails, not just the wiring, like a broken thermometer. Have you checked the sensor's output using diagnostic software?

Can you explain the specific diagnostic procedures you used to determine the sensor was the problem, instead of just the cable or plug?

The sensor readings were erratic and inconsistent, even after checking the wiring. Replacing the temperature sensor is usually quicker and more reliable. I suggest taking it to a workshop for proper sensor diagnostics, calibration and replacement.

Understood. Thanks for confirming the sensor could be the problem, not just the wiring. I'll get a technician to do a full sensor check and replace it if needed.
