Honda Accord Diesel Particulate Filter DPF

A diesel particulate filter is a key part of the emissions system in modern diesel cars, especially in Honda's DTEC engine range. Located in the rear section of the exhaust, it traps soot and unburnt fuel particles, preventing them from reaching the atmosphere.

Made from high-efficiency cordierite ceramic, the filter stores particulates and periodically burns them off via regeneration. This process ensures compliance with Euro standards, keeps fuel use in check, and helps avoid costly fines from emission-related restrictions in local low-emission zones.

Whether you drive a Tourer, Estate, door sedan, or hatchback, your Accord relies on this component for legal and environmental compliance.

Recognising the symptoms of a blocked DPF can help you avoid major repairs. Look for:

DPF or engine management lights

Reduced power and poor throttle response

Higher fuel consumption

Frequent or failed regeneration cycles

Increased tailpipe smoke or backpressure

Ignoring these issues may lead to more serious problems, affecting the lambda sensor, EGR valve, or even your clutch system.

Cleaning your DPF can restore performance and prevent premature replacement. Here's a look at the main cleaning methods.

Passive Regeneration

A natural process that occurs when you drive at motorway speeds. The heat clears out soot without intervention.

Active Regeneration

Managed by the ECU, it injects extra fuel to raise exhaust temps. This works automatically—unless interrupted by short trips.

Fluid or Additive Cleaning

Using supplementary fluid or cleaning additives can help reduce light buildup. They're especially useful for pre-maintenance care.

Manual or Garage-Based Cleaning

For stubborn clogs, head to a local garage for a forced regen, or consider filter replacement if the structure is compromised.

What is DPF regeneration ? It's the process where your Honda clears stored diesel particulate matter from the filter system.

There are three regeneration types:

Passive – Needs sustained driving

Active – Controlled by software

Forced – Requires a technician and diagnostic tools

Each method is vital to clean diesel particulate filter function, helping prevent DPF blockage and ensuring long-term system care.

If you're dealing with heavy ash accumulation or frequent warning resets, it may be time to replace the DPF. Here's how to fit the right part:

Use your model code or registration to find the correct match

Choose a filter fitting kit Euro-approved for your generation

Include all essentials—gaskets, sensors, bolts

Install yourself or let a professional handle the fitting process

We stock full DPF filter fitting kits, including parts for CRV-based platforms.

Blocked filters are more than a hassle—they're preventable. Here's what usually leads to failure:

Repeated short trips or urban drives

Use of incorrect oil or unapproved fuel

Faulty EGR, airflow, or temperature sensors

Poor suspension geometry causing vibration stress

Cracks or gaps in mounting brackets or flex connections

Fixing the symptom without understanding the cause just leads to repeat trips to the shop. Follow up with routine checks on fluid levels and emissions hardware.

What is a DPF and what does it do ?

It's a diesel particulate filter that captures harmful emissions, particularly soot, improving air quality and fuel efficiency.

What are the signs of DPF issues ?

Check for DPF fault lights, poor acceleration, or loss in fuel economy. You might also see messages tied to emission restriction or system errors.

Can I perform DPF cleaning at home ?

Yes, using cleaning DPF additives and by driving at high revs. If the blockage is severe, professional DPF cleaning or replacement may be required.

How often does it need replacing ?

Most units last up to 120,000 miles, depending on car usage and maintenance.
