- A failing camshaft sensor will cause a check engine light, hard starting, rough idle, and stalling.
- The sensor is located on top of the engine and is very easy to replace with a single 10mm bolt.
- Common trouble codes include P0340 and P0341.
- Quality aftermarket sensors are a reliable and cost-effective option for this repair.
Understanding Camshaft Position Sensor Failure
The camshaft position sensor on the 1.6L engine in the 2007-2014 Hyundai Accent is a common replacement item. It lives in a harsh environment of heat and vibration, which can cause it to fail over time. Oil leaks can also damage the sensor. When it fails, it can't send the correct information to the engine computer, leading to a variety of noticeable problems. Ignoring a failing sensor can lead to stalling, poor performance, and eventually a car that won't start at all.
Is it safe to drive with a bad camshaft sensor?
It is risky. A failing sensor can cause your engine to stall at any time, including while driving, which increases the risk of an accident. It's best to get the sensor replaced as soon as you notice symptoms.
Choosing the Right Aftermarket Sensor
For the 2007-2014 Accent, the camshaft position sensor is a straightforward part. While an OEM (Original Equipment Manufacturer) part from Hyundai is always an option, quality aftermarket sensors provide a reliable and cost-effective alternative. Aftermarket brands like Duralast or Carquest are designed to meet or exceed original specifications and are readily available. Since this is a simple sensor and not a complex mechanical part, a reputable aftermarket brand is a sensible choice for most owners. There is no significant evidence from owner forums or technical bulletins to suggest that aftermarket sensors for this specific vehicle are unreliable. The most important factor is ensuring the part is listed as a direct fit for your Accent's model year.

Installation Overview
Replacing the camshaft position sensor on a 2007-2014 Hyundai Accent is a job most DIYers can handle. 🎬 Watch this step-by-step replacement guide for 2006-2011 models. It is located on the top of the engine, on the driver's side of the valve cover, making it easy to access.
- Locate the Sensor: It's on top of the engine, held in by a single 10mm bolt.
- Disconnect the Battery: Always disconnect the negative battery terminal before working on electrical components.
- Remove the Connector: Press the tab on the electrical connector and pull it off the sensor.
- Remove the Bolt: Use a 10mm socket to remove the single retaining bolt.
- Remove the Old Sensor: Gently twist and pull the sensor out of the engine. Make sure the old O-ring comes out with it.
- Install the New Sensor: Lightly oil the new O-ring, then press the new sensor into place. Re-install the 10mm bolt, but don't overtighten it—just snug is fine.
- Reconnect: Plug the electrical connector back in and reconnect the battery.
Known Issues, Recalls, and TSBs
My search of the National Highway Traffic Safety Administration (NHTSA) database and other sources found no specific recalls or widespread common failure patterns for the camshaft position sensor on the 2007-2014 Hyundai Accent. One Technical Service Bulletin (TSB) for the 2007 model mentions an ECM update that changed how the EGR/VVT system readiness was reported, but this is not related to sensor failure. The most common issues are simply age-related failure of the sensor itself or problems with the wiring connector.
