Q: What does code U0352 mean?

Software Incompatibility With NOx Sensor C. U0352 is a network communication code indicating that a control module has detected a software incompatibility with the NOx (nitrogen oxide) sensor designated as C. The computer is not reporting a failed sensor or a wiring fault; it is flagging that the software or calibration in one module does not match what the NOx sensor module expects, so the two cannot communicate reliably.
