Code P2003 Ford Description
The P2003 Ford code indicates that the Diesel Particulate Filter (DPF) efficiency on Bank 2 is below the threshold set by the vehicle's Engine Control Module (ECM). The DPF is a critical component of a modern diesel engine's emissions control system, designed to capture and store harmful particulate matter before releasing it into the atmosphere. When the efficiency of the DPF drops below the specified level, it can lead to a decrease in engine performance, reduced fuel efficiency, and potentially even engine damage if left unaddressed.
Common Causes of P2003 Ford
- Clogged DPF filter
- Faulty DPF pressure sensor
- Exhaust leaks
- Incorrect engine oil or fuel additives
- Faulty DPF regeneration system
Symptoms of P2003 Ford
