Ford cat monitor

Some 2010 Ford F-150 vehicles equipped with 4.6L or 5.4L engines; 2011-2012 F-150s equipped with the 5.0L engine. F-Super Duty vehicles equipped with a 5.4L, 6.2L or 6.8L engine, and Expedition, Navigator, Ranger and Econoline (excluding ambulance package) vehicles built on or before 4-1-12 may exhibit DTC P2270 or P2272.

  1. Using the Integrated Diagnostic System (IDS) scan tool or equivalent, retrieve all continuous memory DTCs. If DTC P2270 or P2272 are not present, this TSB does not apply. If either of these DTCs are present, replace only the affected Catalyst Monitor Sensor as indicated by the DTC observed (P2270 – Bank 1; or P2272 – Bank 2).
