What U060F means
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.
U060F at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U060F
- 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
Common causes of U060F
- Most 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
- Less likelySporadic communication error without hardware fault (cleared and rechecked)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U060F means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 0F | The exact fault in that area. |
What to do next
- Note U060F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U060F
What does U060F mean?
U060F means "Lost Communication With Mass or Volume Air Flow Sensor A". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with U060F?
Drive gently and only to a workshop. With U060F the car can go into limp mode (reduced power) to protect itself.
Will U060F fail an emissions test?
Yes, it can. U060F is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is U060F to fix?
Difficulty: medium. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will U060F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
