P0336
SeriousCrankshaft Position Sensor A Circuit Range/Performance
Treat P0336 with some urgency. A failing crank signal can cause sudden stalling or a no-start, sometimes intermittently. It's usually safe to drive carefully to a shop, but don't put off the repair, especially if you've felt any stalling.
What this code means
The crankshaft position sensor is the engine's master timing reference — it tells the computer exactly where the crank is and how fast it's turning. P0336 means that signal is present but erratic or out of its expected range, often because the sensor's reluctor (tone) ring is damaged or has debris on it, or the sensor itself is failing, or there's a wiring problem. A bad crank signal can cause stalling, rough running, or a no-start, so it's worth sorting out promptly.
Symptoms you might notice
- Stalling, especially when warm
- Hard starting or intermittent no-start
- Rough running or hesitation
- Intermittent loss of power
- Check-engine light
What it costs to fix
Typical range: $120–$500 · about ~0.5–3 hrs of labor
| If the cause is… | Part | Labor |
|---|---|---|
| Crankshaft position sensor | $20–$150 | ~0.5–3 hrs |
| Wiring / connector repair | $10–$120 | ~0.5–1.5 hrs |
The sensor is cheap; the cost is mostly labor and depends entirely on access — some sensors are right up front, others are buried. A damaged reluctor ring is a much bigger job that varies too much to quote.

Frequently asked
Can I drive with P0336?
Cautiously and not for long. The crank sensor is the engine's main timing reference, and a failing one can cause sudden stalling or a no-start. Get it diagnosed quickly and don't rely on the car for important trips until it's fixed.
What's the difference between P0335 and P0336?
P0335 is a missing/erratic crank signal (circuit malfunction); P0336 is a signal that's present but out of range or performance — often a damaged tone ring or a marginal sensor. Both are diagnosed similarly.
Will P0336 cause a no-start?
It can. Without a reliable crankshaft signal the computer doesn't know when to fire spark and fuel, so the engine may crank-no-start or stall once running. Intermittent versions are common.
How much does it cost to fix P0336?
The sensor is cheap; the bill is mostly labor and depends on how buried the sensor is — easy-access engines are low, hard-to-reach ones cost more. A reluctor-ring repair is a major job.
