P0472 Ford Code - Exhaust Pressure Sensor Low
Quick Answer
The Exhaust Back Pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Engine Control Module (ECM), produces a linear analog voltage signal that indicates pressure. Common causes include Faulty Exhaust Back Pressure Sensor, Exhaust Back Pressure Sensor harness is open or shorted, Exhaust Back Pressure Sensor circuit poor electrical connection. 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.
