P0336 on Hyundai by model: symptoms, diagnosis and fix
The crankshaft position sensor on the 1.6L Gamma engine in the Accent fails prematurely, causing no-start conditions, intermittent stalling, and rough running. The sensor's internal hall-effect element degrades from heat exposure near the engine block. Common failure between 60,000-100,000 miles.
Common Symptoms
- Engine stalls randomly while driving
- No-start with cranking but no fire
- Check engine light with P0335 or P0336
- Intermittent rough idle
- Engine dies at red lights
How to Fix
Replace the crankshaft position sensor (Hyundai part 39180-2B000). The sensor is located near the transmission bellhousing on the engine block. Parts cost $30-80, labor $80-150. This is a common DIY repair taking about 30-45 minutes. Always use an OEM sensor as aftermarket sensors have high failure rates.

Owner tips & cautions
- TipKeep a spare crank sensor in the glove box - it takes 30 minutes to replace on the side of the road and costs under $50

On the EF and NF Sonata the crankshaft position sensor degrades thermally: the car starts and runs fine cold, then stalls once the engine reaches full operating temperature and refuses to restart for five to fifteen minutes until the sensor cools, after which the cycle repeats and eventually becomes a permanent no-start. It is one of the most repeated complaints on the EF and NF sub-forums. A closely related contributor on these cars is the engine wiring harness that runs from the firewall over the valve cover and down behind the power steering pump bracket - the insulation is well known for embrittling and falling away, so a car that keeps failing after a new sensor usually has a chafed sensor circuit rather than a bad sensor. This is a Sirius/Delta and Theta I era failure and should not be confused with the later Theta II GDI stall-from-rod-knock pattern, which is accompanied by knocking and metal in the oil.
Common Symptoms
- Engine stalls once warmed up
- Cranks but will not start until it cools for 5-15 minutes
- Intermittent stalling while driving
- Restarts and runs briefly then dies again
- Eventually a permanent no-start
- Poor fuel economy before failure
How to Fix
Replace the crankshaft position sensor (typically $30-90 for the part; on the 2.7L V6 access is behind the timing cover area and labor is higher than on the 4-cylinder). Before condemning the sensor a second time, unwrap and inspect the harness section over the valve cover and behind the power steering pump bracket for cracked or missing insulation and repair the sensor circuit. Confirm with a scan tool that the crank signal drops out at the moment of stall - a camshaft position sensor or failing ignition-side component produces similar symptoms. No recall exists; this is normal-wear replacement.

The 3.8L V6 crankshaft position sensor fails intermittently, causing random stalling, no-start conditions, and rough running. Heat soak worsens the problem — engine stalls after reaching operating temperature then restarts after cooling.
Common Symptoms
- Random stalling while driving
- No-start when hot
- Engine restarts after cooling down
- Check engine light
- Rough idle
How to Fix
Replace crankshaft position sensor. Use OEM or quality aftermarket sensor. Check wiring connector for corrosion or loose pins. Clear stored DTCs after replacement.

Frequently asked questions
What does P0336 mean on a Hyundai?
P0336 stands for "Crankshaft Position Sensor 'A' Circuit Range/Performance." P0336 means the engine control module detected a crankshaft position sensor signal that is present but outside the expected range or pattern — for example, intermittent dropouts, an erratic waveform, or extra/missing pulses. The crankshaft position sensor tells the computer the exact position and speed of the crankshaft, which is essential for timing fuel injection and ignition. When this signal is unreliable, the engine may stumble, stall, hesitate, or be hard to start. Because it underpins basic engine operation, this code should be addressed promptly. On Hyundai it is documented across 3 models: Accent, Sonata, Entourage.
What are the most common causes of P0336?
The most common causes of P0336 are: Failing crankshaft position sensor, Damaged or contaminated reluctor/tone ring (debris, missing teeth), Wiring damage, chafing, or corroded connectors, Incorrect air gap or loose sensor mounting, Electrical interference from nearby high-voltage components, Metal shavings on the sensor tip, ECM/PCM fault (less common). The specific cause varies by vehicle.
How much does it cost to fix P0336 on a Hyundai?
Published repair estimates on Hyundai range from $90 to $450 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
