P2226Barometric Pressure Sensor A Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2226 is the general circuit code for barometric pressure sensor A, the sensor that tells the engine computer the outside air pressure for air-charge, fuel and boost calculations. Ford's OBD summary for 2024-2025 gasoline engines shows how the code appears in current software: every BARO fault is reported as P2226 plus a failure-type byte, -16 for a low voltage (formerly P2228), -17 for high (P2229), -92 for a plausibility error (P2227) and -1F for an erratic signal (P2230). The same list makes all four block auto start-stop. On Ford gasoline engines the sensor sits on the PCM circuit board. A plain P2226 without failure type is rare; sensor B has its own family from P222A. Expect the warning light and a default pressure value.
- What you may notice
- Check engine light
- Auto start-stop no longer works
- Failure-type suffix (-16, -17, -92, -1F) shown with the code on newer scan tools
- Likely causes
- PossibleFault of the barometric sensor built into the engine control module
- PossibleDamaged wiring or loose connector on an external BARO sensor
- Rare5 V reference supply of the sensor pulled down by another faulty sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
