Generic (OBD-II) interpretation

U0697
Lost Communication With Particulate Filter Pressure Sensor D Generic · emissions Data confidence 65%

The control module stopped receiving expected network messages from the Particulate Filter Pressure Sensor D node on the vehicle communication bus.

Symptoms

  • MIL or DPF warning illuminated
  • Possible reduced power or limp mode
  • Possible frequent regeneration attempts

Possible causes

  • Excessive soot load beyond regeneration limits
  • Differential pressure sensor or hose fault
  • Failed or interrupted regenerations (short trips)
  • Exhaust leak upstream of the sensor
  • Underlying engine fault increasing soot output

Recommended checks

  • Read soot load, ash load and differential pressure values
  • Check differential pressure sensor and hoses
  • Verify exhaust gas temperature sensor readings
  • Check for related injection, EGR or boost codes
  • Verify regeneration conditions can be met (trip profile)

U0697:00
Lost Communication with Particulate Filter Pressure Sensor "D" Ford · network Data confidence 94%

Ford documents U0697:00 (no sub type information) for its 2024-2025 gasoline-engine OBD monitor strategy as lost communication with particulate filter pressure sensor "d". This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.

Recommended checks

  • Perform a full module scan
  • Verify battery voltage
  • Check module power supplies and grounds
  • Inspect network wiring and connectors
  • Measure network resistance with power isolated
  • Check applicable OEM service information

Frequently asked questions about U0697

What does U0697 mean?

Lost Communication With Particulate Filter Pressure Sensor D. The control module stopped receiving expected network messages from the Particulate Filter Pressure Sensor D node on the vehicle communication bus.

Is U0697 generic or manufacturer-specific?

U0697 exists both as a generic OBD-II code (same meaning on every make) and with 1 manufacturer-specific interpretation(s): Ford. Always read it in the context of your vehicle.

Can TuningBot remove U0697 at file level?

Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U0697 is removable in your case.
