Possible Causes

Shorted sensor element, Sensor leads shorted together, Wiring shorted to chassis, Moisture in sensor connector

Safety first: Turn off power at the breaker.

Test sensor resistance: Remove the sensor and measure resistance. A very low reading (near 0 Ω) indicates a shorted sensor; replace it.
Inspect wiring: Check the sensor leads and harness for spots where insulation is worn through and wires touch each other or metal.
Dry connectors: If there has been a spill or steam leak, disconnect and dry the sensor connector thoroughly.
Replace sensor or harness: Install new parts as needed and retest.
