What P1106 means on specific makes
Honda / Acura CAUTION
The barometric pressure sensor (built into the MAP sensor on most Hondas) is reading out of expected range, affecting altitude/load fueling corrections.
- Failed MAP/BARO sensor ($40-120)
- Connector/wiring fault
- Internal PCM BARO fault (rare)
Check first: Compare BARO live data to actual atmospheric pressure; inspect MAP sensor and connector.
