P0335 on Hyundai
Crankshaft Position Sensor A Circuit Malfunction
P0335 on Hyundai vehicles indicates crankshaft position sensor a circuit malfunction. Au7o has documented this code across 4 Hyundai models — most commonly on Accent, Elantra, Entourage. This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. Typical repair costs on Hyundai range from $90 to $450, depending on the specific model and root cause.
Common Causes of P0335
- •Failed crankshaft position sensor
- •Damaged, corroded, or loose sensor wiring/connector
- •Metal debris or oil contamination on the sensor tip
- •Damaged or misaligned reluctor (tone) ring
- •Excessive air gap between sensor and tone ring
- •Wiring shorted or open in the sensor circuit
- •Faulty PCM/ECM (rare)
P0335 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 Elantra(1 issue)
- Crankshaft Position Sensor Failure Causing Stalling2011-2017
The crankshaft position sensor fails, causing intermittent stalling, hard starting, and no-start conditions. The problem often worsens when the engine is hot and may not trigger check engine codes initially. Sensor harness corrosion is a common contributing factor.
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 P0335 mean on Hyundai?▼
P0335 stands for "Crankshaft Position Sensor A Circuit Malfunction." This code means the engine computer has lost or detected a faulty signal from the crankshaft position sensor (sensor A), which tells the computer exactly how fast and in what position the crankshaft is rotating. That signal is essential for timing the spark and fuel injection, so a problem here can cause hard starting, stalling, or a no-start condition. The computer sets this code when the crank sensor signal is missing, erratic, or out of its expected pattern. Causes range from a failed sensor or damaged wiring to a problem with the reluctor (tone) ring the sensor reads. On Hyundai specifically, this code is documented across 4 models.
