What does code P2CE8 mean?

Q: What does code P2CE8 mean?

Particulate Filter Pressure Sensor C Circuit High. P2CE8 indicates that the powertrain control module has detected an abnormally high voltage on the signal circuit of particulate filter pressure sensor C, which is used to monitor the pressure drop across the diesel particulate filter. The sensor's output is above the expected range for the current operating conditions, so the module flags the circuit as high.
