P226EParticulate Filter Deteriorated/Missing Substrate (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P226E reports a damaged or missing particulate filter core on bank 2, which only exists where each cylinder bank has its own filter. Ford documents it in its 2024-2025 OBD summary for petrol engines: the gasoline particulate filter check runs once the filter has been above 250 °C for 30 s and exhaust flow lies between 300 and 850 m³/h; if the lowest measured back pressure stays below the missing-brick threshold, a ratio under 1.0, for 5 s, P226E is stored for bank 2 and P226D for bank 1, with Mode 6 results under monitor ID $B3. No public bulletin covers P226E. CARB's missing-substrate rule for diesels follows the same idea. A pressure line problem can mimic a missing core, so check lines and sensor before condemning the filter.
- What you may notice
- MIL on
- Usually no noticeable change in driving behaviour
- Likely causes
- LikelyBank 2 filter core cracked, melted or removed
- PossiblePressure sensing line of bank 2 loose, cracked or blocked
- RareBack pressure sensor reading too low
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
