U060FLost Communication With Mass or Volume Air Flow Sensor A
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Modern hot-film air flow meters often transmit digitally; Bosch lists SENT, frequency and LIN outputs, and many units also carry pressure, temperature or humidity. U060F means sensor A's messages are missing. GM's 2025 tables run it on LIN: no answer to the pressure request for at least 62.5 ms or to the temperature/humidity request for 250 ms, Type A or B by calibration. GM bulletin 24-NA-158 traces P0102 with U060F on 2023/2024 full-size SUVs with L84/L87 V8 engines to water that got into the sensor connector during assembly and replaces sensor and connector. Mitsubishi's 2023 Outlander PHEV sets U060F-00 after a 2 s SENT timeout or data error and then estimates air mass from throttle opening. Ford uses it for SENT units too.
- What you may notice
- Check engine light, often together with an air flow circuit code
- Engine runs on a modelled air mass, with reduced response
- Rough idle or hesitation
- Likely causes
- LikelyWater, corrosion or loose terminals in the air flow sensor connector
- PossibleLIN or SENT line, battery feed or ground to the sensor interrupted
- PossibleAir flow sensor electronics failed
- RareSporadic communication error without hardware fault (cleared and rechecked)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €40 – €400
