1. Reset the ECM with the HDS.

Is Temporary DTC P2227 (P1106)* indicated?

YES - Inspect the air cleaner element, housing, and ducts for obstructions. If there are no obstructions, update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM.

NO - Intermittent failure, system is OK at this time.
