P2461Particulate Filter Pressure Sensor B Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- When pressure sensor B reports a voltage above its usable range, P2461 is stored. Ford sets the limit at 4.90 V for 2 s on the 2013 6.7 L diesel, where B is the differential sensor across the filter, and at 4.73 V for 5 s on the 2024 gasoline particulate filters. An open ground, a signal wire touching the 5 V reference or a battery feed, or a failed sensor are the classic electrical reasons. A Stellantis case from 2025 on the 2023 Jeep Renegade shows a different trigger: condensate inside the tubes between exhaust and differential pressure sensor gave false readings and set P2461 together with P2453 and P2455. The fix there was to dry the hoses with compressed air blown toward the filter, never into the sensor. Because the reading looks like a very full filter, the engine may limit power. The low counterpart is P2460.
- What you may notice
- Malfunction indicator lamp on
- Reduced power because the filter appears heavily loaded
- Likely causes
- LikelyCondensate in the sensor tubes producing false high readings
- PossibleSensor ground open or signal shorted to reference or battery voltage
- PossibleSensor B internally failed with output stuck high
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €0 – €350
