Drive with caution — fix soon.
This code means the engine computer is receiving more timing reference pulses than expected from the high-resolution signal, which it uses to precisely control ignition and fuel. It often results from a damaged reluctor ring, a faulty crankshaft or camshaft position sensor, or electrical noise and wiring problems creating false pulses. It's usually fixed by replacing the failing sensor or damaged ring and repairing any wiring faults.
$150 – $450
Varies by vehicle and root cause.
Often yes for short trips, but don't wait long to fix it. The extra timing pulses can cause rough running, stalling, or hard starts. If the engine surges or cuts out, drive carefully and get it to a shop as soon as you can.
Most repairs cost between $150 and $450. A position sensor and labor make up the bulk of it. The price climbs if a damaged reluctor ring or wiring is the cause, since reaching those parts takes extra time.
It's moderately serious. The car may still run, but the false timing pulses can cause stalling and starting trouble that worsens over time. It's smart to have it diagnosed and repaired before the symptoms get worse.
It means the computer is counting more timing signal pulses per engine revolution than it should. This often comes from a damaged toothed reluctor ring or electrical noise, which fool the sensor into reporting extra signals and confuse the engine's timing.
