P2002 on Hyundai
Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
P2002 on Hyundai vehicles indicates diesel particulate filter efficiency below threshold (bank 1). Au7o has documented this code across 1 Hyundai model — most commonly on Creta. P2002 indicates that the diesel particulate filter (DPF) on bank 1 is performing below its required efficiency threshold. The DPF captures and stores soot from diesel exhaust and periodically burns it off (regeneration); the engine computer monitors exhaust pressure across the filter and other data to judge how well it's trapping and clearing soot. When that efficiency falls too low, this code sets. Symptoms can include reduced power, a clogged-filter warning, frequent or failed regenerations, and increased emissions. Typical repair costs on Hyundai range from $50 to $950, depending on the specific model and root cause.
Common Causes of P2002
- •Clogged or damaged diesel particulate filter
- •Failed or incomplete DPF regeneration (mostly short trips)
- •Faulty differential (DPF) pressure sensor or hoses
- •Faulty exhaust temperature sensor(s)
- •Exhaust leak before or across the DPF
- •Engine running issues causing excess soot (injectors, EGR, turbo)
- •Use of incorrect (non-low-ash) engine oil or fuel quality issues
P2002 on Hyundai by Model
Hyundai Creta(1 issue)
- Diesel Particulate Filter (DPF) Clogging in City-Only Driving (1.5 CRDi BS6)2020-2024
BS6-compliant 1.5L CRDi diesel Cretas (2020 onward) use a DPF without an active heater element, so the filter relies on sustained highway-speed driving to regenerate. Owners whose use is dominated by short, low-speed city trips report soot accumulation that triggers DPF and check-engine warnings, reduced power, and in severe cases a fully clogged filter — one documented case needed a DPF replacement at just 3,500 km. If ignored, the engine enters limp mode and the filter may require replacement costing roughly INR 70,000-80,000 outside warranty.

What does P2002 mean on Hyundai?▼
P2002 stands for "Diesel Particulate Filter Efficiency Below Threshold (Bank 1)." P2002 indicates that the diesel particulate filter (DPF) on bank 1 is performing below its required efficiency threshold. The DPF captures and stores soot from diesel exhaust and periodically burns it off (regeneration); the engine computer monitors exhaust pressure across the filter and other data to judge how well it's trapping and clearing soot. When that efficiency falls too low, this code sets. Symptoms can include reduced power, a clogged-filter warning, frequent or failed regenerations, and increased emissions. On Hyundai specifically, this code is documented across 1 model.
What causes P2002 on Hyundai vehicles?▼
Common causes on Hyundai: Clogged or damaged diesel particulate filter, Failed or incomplete DPF regeneration (mostly short trips), Faulty differential (DPF) pressure sensor or hoses, Faulty exhaust temperature sensor(s), Exhaust leak before or across the DPF. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2002 on a Hyundai?▼
