Possible Causes

Shorted sensor, Sensor wiring shorted to chassis, Moisture in connector

Safety first: Turn off power at the breaker.

Measure sensor resistance: Remove the sensor and test with a multimeter. A very low resistance (near 0 Ω) indicates a short; replace the sensor.
Inspect harness: Look for melted or pinched wires touching metal. Repair or replace as needed.
Dry and clean connectors: If moisture is present, dry thoroughly and use contact cleaner.
Replace EOC if necessary: If the sensor and wiring are good, the control board may be faulty.
