P25B1
Fuel Level Sensor B Stuck
Moderate severity
What it means
Same condition as sensor A stuck, applied to the second fuel level sensor B. Saddle tanks (often AWD vehicles) and large trucks use two sensors — one per tank chamber — averaged for total level. A stuck B leaves only A and reduces accuracy.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
