U0467 Invalid Data Received From Fuel Additive Control Module

U0467 belongs to diesels that use a fuel-borne catalyst. A separate fuel additive control module meters a metal-based additive from its own reservoir into the fuel after refuelling, so that soot trapped in the particulate filter ignites at about 350-450 °C instead of above 600 °C. The engine controller sets U0467 when the module's reports, for example dosed quantity, reservoir level or fault status, arrive corrupt or contradict each other. No manufacturer documents U0467 publicly. A Ford patent (US 6,276,310) outlines how such a dosing processor works with the engine controller, which supplies fuel consumption so the additive ratio stays constant. CARB requires the particulate filter and its regeneration to be monitored, so the fault counts as emission-related and a MIL is likely. U0118 is lost contact. Unrepaired, the filter clogs.

Likely causes

Corroded connector or damaged wiring at the additive pump module near the tank
Faulty additive level sensor feeding implausible values into the module
Module not adapted after refilling the additive or replacing the particulate filter
Internal fault in the fuel additive control module

Symptoms

  • Check engine lamp or particulate filter warning
  • Regeneration becomes more frequent or incomplete
  • Reduced engine power once the filter loads up
