DPF Cleaning & Regen in Jackson, MS
If your diesel truck is derating, throwing high-back-pressure codes, or asking for a regen it can't complete, the diesel particulate filter (DPF) is usually involved. But the answer isn't always a new DPF. Wilkerson's runs DPF cleaning, regen support, and sensor diagnostics on diesel trucks in Jackson, MS — usually for a fraction of what a new DPF would cost.
We start with the data, not the parts catalog. Back-pressure readings, soot-load values, sensor health, regen history. Most “DPF problems” we see are actually NOx-sensor failures, EGR issues, bad turbos, leaking exhaust upstream, or worn injectors generating too much soot. We diagnose what's actually wrong before we sell a $3,000 part.
When the DPF itself needs cleaning, we do it. When it's damaged past cleaning, we replace it. We do not perform illegal DPF delete work — we're an EPA-compliant shop. When we say it's fixed, the truck is legal.
What's included
Everything we do on a dpf cleaning visit.
Back-pressure & soot-load diagnostics
Live data on the truck. We read the system before we touch the filter.
DPF cleaning
Full filter cleaning service when the data says cleaning is the right call.
Forced regeneration support
When the truck can't complete a passive or active regen, we run it on the bay.
DPF replacement (when warranted)
If the filter is cracked or melt-damaged past cleaning, we replace — but only when the data says so.
Sensor diagnostics
Pressure differential sensors, exhaust temperature sensors, NOx sensors that drive bogus DPF codes.
Upstream root-cause work
EGR leaks, turbo issues, injector problems, exhaust leaks that cause repeat DPF failures.
EPA-compliant only
No illegal delete or tune work. When we fix it, it's legal.
Signs you need this
When to call us.
Most of these symptoms point to the work on this page. A few point somewhere else — and we'll tell you straight either way.
- Truck derated to 5 mph or 55 mph
- Check-engine light with DPF or high-back-pressure codes
- Frequent regens that won't complete
- Power loss under load that gets worse with miles
- Dash asking for a parked regen
- Black exhaust smoke (excess soot upstream of the DPF)
Pricing & estimates
No surprises on the invoice.
Diagnostic starts with live data on the truck — back-pressure, soot load, regen history. Written estimate before any cleaning or parts. Many trucks get back on the road for a cleaning fee instead of a $3,000+ DPF replacement.
Our process
No surprises between the call and the invoice.
Four steps from the first call to the keys back in your hand. No mystery, no upsell theater.

You approve
Nothing happens without a green light from you. If we find more during the repair, we stop and call before we keep going.

Repair + written warranty
Same name on the invoice every time. Our own written warranty on covered work — and the family promise behind it.
Why Wilkerson's
Three reasons people keep coming back.
- Then parts
- Data first
- Compliant only
- EPA
- On the bay
- Same day
Most shops swap the DPF and hope. We read the truck — back-pressure, soot load, sensor health — and tell you what's actually wrong.
We do not delete or tune around emissions. When we sign it off, the truck is legal, the engine warranty stays intact, and DOT passes.
Most DPF diagnostics happen same day. Cleaning or forced regen often turns same-day or next-day, not three weeks at the dealer.
Frequently asked
What people ask before they bring the truck in.
Tap any question to expand the answer.
Depends on the data. If back-pressure is high but the filter is structurally sound, cleaning is the answer — and it's a fraction of replacement cost. If the filter is cracked or melt-damaged, it's replacement. We tell you which after we read the truck.
Almost always something upstream — leaking EGR, bad injectors generating too much soot, exhaust leaks, sensor issues. If your DPF has failed twice, the third one will fail too. We fix the upstream root cause.
No. DPF delete is illegal under the Clean Air Act, voids your engine warranty, and will fail any DOT inspection. We're EPA-compliant — cleaning, repair, replacement only.
Yes. When the truck can't complete a passive or active regen on its own, we run a forced (parked) regen on the bay. Often the cheapest fix when the system is just behind on burn-off.
Most cleaning jobs are same-day or next-day. Diagnostic happens the same day in nearly every case.
