What does code P2CE5 mean?

Q: What does code P2CE5 mean?

Particulate Filter Pressure Sensor C Circuit. P2CE5 indicates that the powertrain control module has detected an electrical fault in the signal circuit for the particulate filter pressure sensor, specifically the 'C' circuit. This sensor measures the pressure difference across the diesel particulate filter to help the computer estimate soot loading and trigger regeneration; the code means the voltage on that circuit is outside the expected range, not necessarily that the filter itself is bad.
