P2462Particulate Filter Pressure Sensor B Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2462 covers a sensor B signal that drops out or jumps for short moments without staying outside its range long enough for the low or high codes. Ford is the only maker found documenting it: the 2024 gasoline particulate filter summary lists P2462 next to P2460 and P2461 in the continuously running analog circuit check, with about 5 s needed to register a fault, and no separate threshold is published. On Ford's older 6.7 L diesel the B position belongs to the delta pressure unit mounted at the filter. The cause is nearly always mechanical or electrical intermittency: a terminal that loses contact as the engine shakes, a harness rubbing on a bracket, or moisture that comes and goes in the connector. Wiggling the harness while watching live data usually finds it. Sensor A has the matching code P2456.
- What you may notice
- Malfunction indicator lamp on, sometimes only after rough roads or rain
- Pressure reading jumping in live data

- PossibleHarness rubbing on a bracket or exhaust part
- PossibleMoisture entering the connector intermittently
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
