P0336 on Hyundai
Crankshaft Position Sensor 'A' Circuit Range/Performance
P0336 on Hyundai vehicles indicates crankshaft position sensor 'a' circuit range/performance. Au7o has documented this code across 3 Hyundai models — most commonly on Accent, Entourage, Sonata. 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. Typical repair costs on Hyundai range from $90 to $450, depending on the specific model and root cause.
Common Causes of P0336
- •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)
P0336 on Hyundai by Model
Hyundai Accent(1 issue)
- Crankshaft Position Sensor Failure2012-2022
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.
Hyundai Entourage(1 issue)
- Crankshaft Position Sensor Failure Causing Stalling2007-2009
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.
Hyundai Sonata(1 issue)
- Crankshaft Position Sensor Heat-Soak Failure Causing Hot Stall and Extended No-Start (EF/NF)2001-2010
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.

What does P0336 mean on 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 specifically, this code is documented across 3 models.
What causes P0336 on Hyundai vehicles?▼
Common causes on Hyundai: 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.
