U067FLost Communication With Barometric Pressure Sensor A
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- Barometric pressure sensor A is normally the ambient sensor that corrects fueling, boost targets and many diagnostics for altitude; CARB requires barometric pressure, measured or estimated, in the OBD data stream. U067F covers a digital version of that sensor whose messages stop arriving. GM's dual-throttle program 23OBDG07 does read a digital ambient sensor, but files its faults under P-codes: a CRC error or a short reported in message A sets P2228 or P2229, and defect or queue-full flags set P2227, each after 2 s with MIL in one trip. Ford's 2024 gasoline and 2023 diesel summaries keep sensor A analog (P2228). No published table therefore assigns U067F. Because ambient pressure may also be estimated, as CARB allows, drivability rarely suffers.
- What you may notice
- Check engine light
- Slightly off fueling or boost at altitude
- Other diagnostics may be suspended
- Likely causes
- LikelyData, supply or ground wire to the barometric sensor interrupted
- PossibleConnector loose or corroded
- PossibleBarometric sensor electronics failed
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €40 – €300
