How to fix it

  1. Cut power at the breaker.
  2. Unplug the temperature sensor and measure resistance — far below 1080 ohms confirms a short.
  3. Replace the sensor if shorted.
  4. If a new sensor still reads short at the PCB, inspect the harness for damage where it routes through the cavity wall.
