Drive with caution — fix soon.
This code means the fuel temperature sensor B circuit is reading higher voltage than expected, which often means the signal is stuck high or the circuit is open. Typical causes include a failed sensor, an open or broken wire, or a poor connector. It's usually repaired by fixing the circuit or replacing the sensor after testing, and rarely involves major engine repair.
$120 – $350
Varies by vehicle and root cause.
Usually yes for short-term driving, since this is a sensor signal problem and not a mechanical failure. Get it diagnosed soon, particularly if you notice rough running or hard starts.
Most repairs land between $120 and $350. Whether the fix is a new sensor or wiring repair is the main thing that moves the price up or down.
It's generally a low-to-moderate issue. It rarely strands you, but the faulty reading can affect fuel management, so it's smart to fix it before it causes other problems.
High input often points to an open circuit or broken signal wire, but it can also be a failed sensor or bad connector. Testing the circuit is the only way to know for sure.
