Ford Excursion P0720 Code: Engine Dies in Gear or Idle - Diagnosis and Fix
My Ford Excursion is showing a P0720 diagnostic code. I recently followed the recommendation from Ford service to replace the spark plugs, but the issue persists. The engine starts successfully but fails to stay running. When placed in gear and given throttle input, it cuts out unexpectedly. It also occasionally stalls at idle. This behavior suggests a potential transmission or sensor-related problem. I'm seeking advice on how to properly diagnose and resolve this P0720 code, especially since the issue occurs under both acceleration and idle conditions.
P0720 indicates an Output Speed Sensor Circuit Malfunction. Please check the sensor circuit for proper power supply, reference voltage, ground connection, and wiring integrity. Inspect the output speed sensor located in the transmission for damage or loose connections. Ensure all electrical components are functioning correctly before considering further repairs. Good luck — please update with your findings.
