What does P2CE7 mean?
The ECM detects a circuit low fault on the particulate filter pressure sensor c. Reading cannot be used reliably for control.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.

- Power loss / limp mode
- Increased fuel consumption
- Failed forced regeneration attempts
Common causes
- High Signal wire shorted to ground
- Medium Internal sensor short
- Low Connector pins corroded - high contact resistance
