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.

Likely causes

Water, corrosion or loose terminals in the air flow sensor connector
LIN or SENT line, battery feed or ground to the sensor interrupted
Air flow sensor electronics failed
Sporadic communication error without hardware fault (cleared and rechecked)

Symptoms

  • 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
