U060CLost Communication With Turbocharger/Supercharger Boost Sensor B
- Generic OBD-II code · Network
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Boost sensor B is needed where charge pressure is measured twice: on twin-turbo V engines with one charge path per bank, on two-stage systems between the stages, or after the charge air cooler in addition to sensor A. When it is a digital SENT device, its frames carry pressure, often a temperature value, a status nibble and a CRC. U060C sets when those frames from sensor B are missing, corrupt or flagged as invalid by the sensor itself. No manufacturer documents this code publicly; the logic follows Audi's bulletin for U060B and the CARB 1968.2 rule that lost communication on a digital input needs its own code. P0239 to P0242 are the analog counterparts, and P023E compares sensor B with manifold pressure. The controller usually limits boost on that branch.
- What you may notice
- Check engine light
- Reduced power with boost limited
- Likely causes
- LikelyDamaged wiring to boost sensor B, often near hot turbo plumbing
- PossibleBoost sensor B electronics failed
- RareLoose or oil-soaked connector at sensor B
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
