Drive with caution — fix soon.
This code means the engine computer detected a fault in the circuit for crankshaft position sensor B, which tracks the engine's rotation and timing. It's usually caused by a failing sensor, damaged wiring or connectors, or a poor ground. It's a fairly common code and is normally fixed by replacing the sensor or repairing the circuit.
$150 – $500
Varies by vehicle and root cause.
For short trips usually yes, but don't rely on it. The crankshaft sensor controls engine timing, and if it fails completely the engine can stall or refuse to start, so get it checked promptly.
Most repairs cost between $150 and $500. The sensor itself is often affordable, but labor depends on how hard it is to reach on your engine.
It's moderate but worth taking seriously. The engine may run for now, but a failing crankshaft sensor can cause sudden stalling or a no-start, which is why prompt repair is recommended.
Yes. The crankshaft sensor tells the computer the engine's exact position, and if that signal cuts out the engine can stall instantly. That's why intermittent stalling is a common complaint with this code.
