Code P246C Ford Description
The P246C diagnostic trouble code (DTC) for Ford vehicles indicates that there is a restriction in the diesel particulate filter (DPF) system, leading to limited power output. The diesel particulate filter is designed to capture and remove harmful soot particles from the exhaust gases of a diesel engine. When a restriction occurs in the DPF, it can impede the flow of exhaust gases, leading to reduced engine performance and efficiency.
Common Causes of P246C Ford
- Lack of proper DPF regeneration
- Faulty DPF pressure sensor
- Clogged DPF filter
- Exhaust leaks near the DPF
- Engine tune-up issues
Symptoms of P246C Ford
- Reduced engine power
- Decreased fuel efficiency
- Engine misfires or hesitation
- Illuminated check engine light
- Increased exhaust smoke
How to Fix P246C Ford
- Perform a diagnostic scan to confirm the P246C code and identify any other related codes.
- Inspect the DPF system for physical damage, leaks, or excessive soot buildup.
- Check the DPF pressure sensor for proper operation and replace if necessary.
- Perform a forced regeneration of the DPF using a diagnostic tool.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P246C Ford
The repair costs for addressing a P246C DTC can range from $200 to $800, depending on the specific cause of the issue and any parts that may need to be replaced.
