U060DLost Communication With Turbocharger/Supercharger Boost Sensor C

  • Generic OBD-II code · Network
  • Turns on the check-engine light
  • Matters for the ITP
  • Can trigger limp mode
How the car detects it
A third boost sensor C appears only on complex charging layouts, for instance sequential or two-stage turbo systems with pressure taps between and after the stages, or engines that add an electric compressor. U060D reports that the controller has lost the digital link to this sensor: no SENT frame inside the expected time, a frame failing its check, or a sensor that transmits only its reserved error value, a feature found on pressure chips such as Melexis' MLX90818. No manufacturer documents U060D publicly, so its use rests on the CARB 1968.2 requirement and the pattern of U060B. Which physical sensor is called C is a manufacturer decision. P25F2 to P25F5 cover the analog circuit of the same sensor. Expect boost to be limited on the affected stage.
What you may notice
  • Check engine light
  • Power loss when the affected stage would build boost
Likely causes
  • LikelyOpen or shorted SENT, supply or ground wire to sensor C
  • PossibleSensor C sending only its error value
  • RareCorroded connector at sensor C
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
