P047A Ford Code - Exhaust Pressure Sensor 'B' Circuit
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 'B', Exhaust Back Pressure Sensor 'B' harness is open or shorted, Exhaust Back Pressure Sensor 'B' circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
