Q: What does code P2CEA mean?

Particulate Filter Pressure Sensor D Circuit. P2CEA indicates that the powertrain control module (PCM) has detected an electrical fault in the signal circuit for the particulate filter pressure sensor, specifically in the 'D' circuit, which is one of multiple pressure sensor circuits used to monitor the filter. The PCM compares the sensor's output to expected values and sets this code when the signal is out of range, intermittent, or implausible, pointing to a wiring, connector, or sensor issue rather than a mechanical filter problem.
