P0335 on Hyundai: How to Diagnose & Fix
Crankshaft Position Sensor A Circuit Malfunction

P0335 on Hyundai by model: symptoms, diagnosis and fix
Owners of 2011-2013 Elantras report on NHTSA that a failing crankshaft position sensor makes the engine idle very low and stall when coming to a stop, crank hard or fail to start, and lose power; some notice the tachometer drop to zero. The dealer may find no stored codes at first. Hyundai has not issued a recall for it.
Common Symptoms
- Engine stalls when coming to a stop
- Hard starting or no start
- Tachometer drops to zero
- Loss of power while driving
How to Fix
Have the crankshaft position sensor and its connector tested, and replace the sensor if it is faulty (OEM part recommended). Clear codes and test drive to confirm the stalling has stopped.

Owner tips & cautions
- TipConsider OEM parts for critical components like sensors and electrical parts - aftermarket can be unreliable
- TipGet a proper diagnosis before replacing parts - similar symptoms can have different causes

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.

Frequently asked questions
What does P0335 mean on a 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 it is documented across 2 models: Elantra, Sonata.
What are the most common causes of P0335?
The most common causes of P0335 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0335 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.
