P0335 on Hyundai vehicles
Crankshaft Position Sensor Circuit Fault — what it means on a Hyundai, whether it's safe to drive, and the fixes by model and year.
P0335 on a Hyundai means crankshaft position sensor circuit fault. Stop driving and diagnose it before continuing — it can signal an unsafe condition. The most common cause is failed crankshaft position sensor (heat-related failure) (typically $100–$400). Pick your Hyundai model below for its known failure patterns, recalls, and TSBs.
What does P0335 mean on a Hyundai?
P0335 is set when the engine control module does not receive a valid signal from the crankshaft position sensor. The crank sensor is the primary timing reference for the entire engine — fuel injection, ignition timing, and cam position correlation all depend on a clean crank signal. Without it, the engine will not start, or it will stall as soon as the signal drops out.
P0335 is a standardized OBD-II code, so its definition is the same on every Hyundai. What differs by model and engine is which cause is most likely — pick your Hyundai model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Hyundai with P0335?
No. P0335 is a critical-severity code — avoid driving your Hyundai until it is diagnosed and repaired, as it can indicate an unsafe condition or risk further damage.
What causes P0335 on a Hyundai?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Failed crankshaft position sensor (heat-related failure) — Heat-soak failure pattern is the textbook P0335 — fails when hot, recovers when cold. | Most common | $100–$400 |
| Damaged or melted sensor wiring near the exhaust | Common | $80–$350 |
| Corroded crank sensor connector | Common | $30–$200 |
| Damaged crank reluctor / tone ring (rare, requires teardown) | Rare | $1,500–$4,000 |
| Loose or improperly torqued sensor (cannot read gap correctly) | Occasional | $20–$100 |
| Failed PCM input (rare) | Rare | $400–$1,500 |
Repair costs are typical US ranges and vary by Hyundai model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What are the symptoms of P0335 on a Hyundai?
Check Engine Light is illuminated. Engine cranks but will not start. Intermittent stalling that worsens with engine heat. Hard starting after a long drive (heat-soak failure). Sudden stalling at highway speed with restart difficulty. Tachometer reads zero or fluctuates while running. Hard cold start with extended crank time
