P1405 Ford Code - DPF EGR Sensor Circuit High Voltage Detected

Quick Answer

The P1405 Ford code indicates that the DPF (Diesel Particulate Filter) EGR (Exhaust Gas Recirculation) sensor circuit has detected a high voltage. Common causes include Faulty DPF EGR sensor, Wiring or connection issues in the sensor circuit, Carbon buildup in the EGR system. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
