Code P0335 Hyundai Description
The P0335 diagnostic trouble code (DTC) for Hyundai vehicles indicates a problem with the crankshaft position sensor 'A' circuit. The crankshaft position sensor is a vital component in the engine management system, as it helps the engine control module (ECM) determine the position of the crankshaft and piston. This information is crucial for ignition timing and fuel injection, ensuring the engine runs smoothly and efficiently. When the ECM detects an issue with the crankshaft position sensor circuit, it can lead to poor engine performance, misfires, stalling, and even engine damage if left unaddressed.
Common Causes of P0335 Hyundai
- Faulty crankshaft position sensor
- Damaged or corroded wiring/connectors in the sensor circuit
- Issues with the ECM
- Poor electrical connection
- Timing belt or chain issues affecting sensor signal
Symptoms of P0335 Hyundai
- Engine misfires or rough idle
- Difficulty starting the engine
- Stalling or engine shutting off while driving
- Reduced fuel efficiency
- Check Engine Light illuminated on the dashboard
How to Fix P0335 Hyundai
- Diagnose the issue with a scan tool to confirm the P0335 code and pinpoint the problem.
- Inspect the wiring and connectors for damage or corrosion, repairing or replacing as needed.
- Test the crankshaft position sensor for proper operation, replacing it if faulty.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.

i replased the sensor and still geting the code
car wont start when it gets hot no spark -
Same thing happened to me, mine is a 2004 Hyundai Sonata 2.4L. Any Possible Solutions would be Helpful!!!

Please verified that the sensor was properly installed. If the sensor was installed on the wrong position the engine will not start. Even if the bolt it's tight, it doesn't mean that the sensor was properly installed.

I have a hyundai accent 2005 with a 3 month old battery and a new starter that wont turn on. Once it turns on it stays on . but when it doesn't turn on it takes like an hour before it'll start up for me. I got the error code P0128 and P0335 and I have no idea how to begin troubleshooting this to pinpoint the problem
-
Does the engine crank but won't start or the engine won't crank at all?
The P0128 is for coolant temperature sensor and the P0335 for the crankshaft position sensor, both sensor can cause the engine to crank but no start (or it take longer to start).
I recommend starting by replacing the crankshaft position sensor.

New ckp sensor but won't start only crank and I'm getting the dtc p0335, any idea would be helpful

Do you have any more codes?
Other than the Crankshaft Position Sensor, the only other thing that I have seen causing a no start situation is a broken timing belt.

Those look like ELM327 scan tool commands, not a fault code or vehicle symptom.
Commands like ATSP and ATSH are used to configure the communication protocol and header when sending manual requests to a vehicle’s ECU. They’re typically used in advanced diagnostics when someone is trying to communicate directly with a module using a scan tool or terminal.
For example:
• ATSP selects the communication protocol
• ATSH sets the header address for the module you’re trying to talk toBy themselves, those commands don’t indicate a problem with the crankshaft position sensor or a P0335 condition.
If you’re dealing with a P0335, the focus should be on things like the crankshaft position sensor, its wiring, connector condition, or the reluctor wheel on the crankshaft.
If you can share the vehicle year, model, engine, and the symptoms (no start, stalling, intermittent shutoff, etc.), it will be much easier to point you in the right direction.

If you are still have the P0335 code after replacing the sensor, then more than likely you have a problem with the timing belt. Either the timing belt tensioner or a stretched timing belt.
