What does code P2CE6 mean?

Q: What does code P2CE6 mean?

Particulate Filter Pressure Sensor C Range/Performance. P2CE6 means the engine computer has detected that the particulate filter pressure sensor C is reporting a signal outside its expected range or behaving erratically during the self-test. The sensor measures the pressure difference across the diesel particulate filter (DPF), and the computer uses that reading to judge soot loading and trigger regeneration; a range or performance fault means the signal is not tracking reality.
