Drive with caution — fix soon.
This code means the engine computer detected a low voltage signal from crankshaft position sensor B. It's typically caused by a shorted or grounded wire, a failing sensor, corroded connectors, or a poor ground. It's a common circuit fault and is usually fixed by repairing the wiring or replacing the sensor.
$150 – $500
Varies by vehicle and root cause.
For short trips usually yes, but don't depend on it. The low signal can cause stalling or a no-start, so it's best to have it diagnosed and repaired before the sensor fails completely.
Most repairs run $150 to $500. A wiring repair can be on the lower end, while replacing the sensor with labor lands toward the middle or higher of that range.
It's moderate. The engine may still run, but a low or dropping crankshaft signal can cause sudden stalling, so it's worth addressing without much delay.
Not always. Low input often comes from a shorted wire, corroded connector, or bad ground rather than the sensor. A technician should check the wiring before condemning the sensor.
