Can I drive with P2002?

Yes, but drive carefully and get it checked soon. Diesel soot filter is degraded or leaking; car remains drivable but emissions are compromised.

What does P2002 mean?

P2002 stands for Diesel Particulate Filter Efficiency Below Threshold (Bank 1).

Symptoms you may notice

• Check engine light steadily illuminated
• Slight hesitation or change in throttle response
• Possible increase in fuel consumption

How much does it cost to fix?

Repair costs for code P2002 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:

• Cracked or degraded Diesel Particulate Filter (DPF)
  $800-$2500 common
• Faulty DPF differential pressure sensor
  $90-$240 possible
• Exhaust pressure sensor tube cracked or melted
  $40-$120 possible
• Upstream engine soot generation (boost leak or bad injector)
  $150-$500 rare

What to do next

1. Check DPF pressure sensor rubber sampling hoses for burns or cracks.
2. Perform a highway regeneration drive if vehicle requests DPF cleaning.
3. Have the DPF filter inspected for internal honeycomb fracture.

About this code

Code P2002 applies to diesel vehicles with an exhaust DPF soot trap. It means the pressure drop across the filter indicates that soot is passing through without being captured. While you can drive normally, ignored DPF issues can lead to severe limp mode down the road.
