Drivable short-term, but fix now to avoid damage.
This code means the engine computer is seeing a higher-than-expected voltage from the crankshaft position sensor circuit, which usually points to a wiring fault, bad connector, or a failing sensor. The crankshaft sensor is essential for timing the spark and fuel, so a faulty signal can cause stalling or no-start conditions. Repairs typically involve inspecting and repairing the wiring or replacing the sensor.
$120 – $400
Varies by vehicle and root cause.
It's risky. The engine may run fine for now, but a bad crankshaft sensor signal can cause sudden stalling or a no-start, so only drive short distances and get it checked soon.
Most repairs land between $120 and $400. If it's just the sensor the cost is lower, but wiring repairs or hard-to-reach sensor locations can push it higher.
Yes, it can be. While it's not an immediate safety hazard, the crankshaft sensor is critical to the engine running, so an unreliable signal can leave you stranded.
It monitors the exact position and speed of the crankshaft so the computer can time the spark and fuel injection correctly. Without a good signal, the engine can't run properly.
