What P2BA5 means

P2BA5
Particulate Filter Feedgas Performance Generic · emissions Data confidence 65%

The control module judged the Particulate Filter Feedgas behaviour implausible for the current operating conditions.

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)
