Particulate Filter Pressure Sensor B Circuit High

Where it lives

For P2461, the sensor sits on the circuit this code reports. The description of P2461 reports a fault at the sensor.

Check these first

• A blocked DPF pressure hose at sensor B holding pressure
• A sensor B signal wire shorted to voltage
• A failed particulate filter pressure sensor B
• A clogged DPF driving the pressure reading high

What to do next

1. Read particulate filter pressure sensor B on a scan tool
2. Check the sensor B pressure hoses for a soot blockage
3. Test the sensor B signal wire for a short to voltage
4. Inspect the DPF for excessive soot loading
5. Replace the particulate filter pressure sensor B if the circuit tests good
6. Clear the code and retest
