Drive with caution — fix soon.
This code means the engine control module is counting fewer high-resolution timing pulses than expected from the 'B' reference sensor, usually a crankshaft or camshaft position sensor. It typically points to a failing sensor, damaged wiring or connector, or worn or damaged teeth on the reluctor ring. It's usually fixable by replacing the sensor or repairing the circuit, without major engine work.
$150 – $450
Varies by vehicle and root cause.
For short trips, usually yes, but you shouldn't rely on it. If the engine stumbles or is hard to start, get it checked promptly to avoid being stranded.
Most repairs run between $150 and $450. A simple sensor replacement is on the lower end, while wiring or reluctor ring repairs cost more.
It's moderately serious. It won't usually damage your engine, but it can cause poor running and stalling, so it's best to address it soon.
It means the 'B' timing sensor is sending fewer signal pulses than the computer expects per engine revolution, often from a worn sensor, bad wiring, or damaged trigger wheel teeth.
