Possible Causes

Shorted sensor, Pinched sensor wiring, Moisture in sensor connector

Safety first: Turn off power at the breaker.

Steps to check:

Inspect harness: Remove the rear panel and inspect the sensor wires for pinching or melted insulation.
Test sensor: Disconnect the sensor and measure resistance. A very low reading (near 0 Ω) indicates a shorted sensor; replace it.
Check for shorts to chassis: With the sensor disconnected, test each sensor wire to the metal chassis. Any continuity indicates a short; repair or replace the harness.
