P25B2Fuel Level Sensor A or B Stuck
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P25B2 is the shared variant for tanks with two senders: the module has found that the level information is frozen but does not commit to which of the two senders is responsible. Ford lists it next to P25B0 and P25B1 under the same consumption-versus-reading check (100 to 120 miles, 25 to 60 % allowed mismatch) and, unlike the other two, keeps P25B2 as its own base code in the 2024 summary with failure type 00. When a calibration uses P25B2 instead of the single-sender codes is not explained publicly; a plausible case is a system that only evaluates the combined value of both senders. For the repair this means both senders, the jet pump and the wiring to each must be checked one after another, ideally by comparing each raw reading with the actual tank content. The 2014 Boss 302S list marks P25B2 as a lamp code.
