P0336 — Crankshaft Position Sensor A Circuit Range/Performance
Drivable short-term, but fix now to avoid damage.
What P0336 means
This code means the crankshaft position sensor signal is present but erratic or out of its expected range, so the computer struggles to track the engine's exact position. It's commonly caused by a failing sensor, damaged wiring, a worn reluctor or trigger wheel, or sensor air-gap problems. The usual fix is replacing the crankshaft position sensor and checking the wiring and reluctor ring.
Common symptoms
- Check engine light is on
- Engine misfires or runs rough
- Hard starting or intermittent no-start
- Engine may stall unexpectedly
- Hesitation or jerking during acceleration
Common causes
- Failing crankshaft position sensor
- Damaged or corroded sensor wiring
- Worn or damaged reluctor/trigger wheel teeth
- Incorrect sensor air gap or loose mounting
- Poor electrical connection at the sensor
Typical repair cost
$180 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0336 code?
It's risky. The car may still run, but an unreliable crankshaft sensor can cause sudden stalling or a no-start situation. Limit your driving to getting it to a shop, and don't plan any long trips until it's repaired.
How much does it cost to fix a P0336 code?
Most repairs fall between $180 and $500. The sensor itself is moderately priced, but on some engines it's in a hard-to-reach spot, which increases labor. If the reluctor wheel is damaged, costs can be higher.
Is a P0336 code serious?
Yes, it's on the serious side. The crankshaft position sensor is essential for the engine to run, so a faulty signal can lead to stalling or failure to start. It should be diagnosed and fixed promptly.
Why does a crankshaft sensor cause stalling?
The computer relies on this sensor to time the spark and fuel injection. If the signal cuts out or becomes erratic, the engine can lose spark and fuel timing momentarily, causing it to stumble or shut off.
