Code P140D Ford Description
The P140D Ford code indicates a problem with the Exhaust Gas Recirculation (EGR) control circuit 'B', specifically a range/performance issue. The EGR system is crucial for reducing emissions and improving fuel efficiency by recirculating a portion of exhaust gases back into the engine cylinders. The control circuit 'B' is responsible for monitoring and adjusting the EGR system's operation within a specified range to optimize engine performance. When this code is triggered, it means that the EGR control circuit 'B' is not functioning as intended, leading to potential performance issues and increased emissions.
Common Causes of P140D Ford
- Faulty EGR valve
- Damaged wiring or connectors in the EGR control circuit
- Clogged EGR passage
- Malfunctioning EGR position sensor
- Carbon buildup in the EGR system
