Chances are, a faulty camshaft position sensor could be the culprit. This tiny but mighty component plays a crucial role in your engine’s performance, ensuring everything runs smoothly.
Replacing a bad sensor can bring your car back to life, improving fuel efficiency and overall drivability.

Why Your 2011 Hyundai Elantra Needs a Good Camshaft Position Sensor
Before we dive into the reviews, let’s quickly chat about what this sensor actually does. Think of your engine as a well-orchestrated band. The camshaft position sensor acts like the conductor, telling your car’s computer (the ECU) exactly where the camshaft is in its rotation. This information is vital for the ECU to precisely control spark timing and fuel injection, ensuring your engine fires at just the right moment.
When this sensor goes bad, your 2011 Hyundai Elantra might display a range of frustrating symptoms, including:
- Check Engine Light (CEL): Often with codes like P0340 or P0341.
- Difficulty Starting: Especially when the engine is warm.
- Engine Stalling: Unexpectedly shutting off, sometimes while driving.
- Rough Idling or Misfires: The engine might shake or feel choppy.

FAQ Section
Q1: What does a camshaft position sensor do in my 2011 Hyundai Elantra?
A: The camshaft position sensor (CMP sensor) monitors the speed and position of the camshaft, which controls the opening and closing of your engine’s valves. It sends this information to the engine control unit (ECU), allowing the ECU to accurately determine spark timing and fuel injection for optimal engine performance and emissions.
Q2: What are the common symptoms of a failing camshaft position sensor in a 2011 Hyundai Elantra?
A: You might experience a lit check engine light (often with codes like P0340 or P0341), difficulty starting (especially when warm), engine stalling, rough idling, engine misfires, poor acceleration, or decreased fuel economy.
Q3: Can I drive my 2011 Hyundai Elantra with a bad camshaft position sensor?
A: While your car might still run, it’s not recommended. A failing sensor can lead to unreliable engine operation, including unexpected stalling, reduced power, and increased fuel consumption. Prolonged driving with a faulty sensor could potentially cause further damage to other engine components due to incorrect timing.
Q4: Is it difficult to replace the camshaft position sensor on a 2011 Hyundai Elantra?
A: For many 2011 Hyundai Elantra models, replacing the camshaft position sensor is considered a relatively easy DIY job. It usually involves locating the sensor (often on the cylinder head), disconnecting its electrical connector, unbolting it, and then installing the new one. Always consult your vehicle’s service manual or an online tutorial specific to your Elantra’s engine for precise instructions.
Q5: What’s the difference between OEM and aftermarket camshaft position sensors?
A: OEM (Original Equipment Manufacturer) sensors are made by the same company that supplied the part to Hyundai when your car was built. Aftermarket sensors are made by other companies, often offering a similar performance at a lower cost. Many aftermarket sensors, like those reviewed above, meet or exceed OEM specifications, providing excellent value and reliability.
Q6: How do I know if the new sensor is working correctly after installation?
A: After installing the new sensor and clearing any stored diagnostic trouble codes (DTCs) with an OBD-II scanner, drive your 2011 Hyundai Elantra for a bit. If the check engine light stays off, and you no longer experience the symptoms like rough idling, stalling, or hard starting, your new sensor is likely working correctly.
Q7: Why are some camshaft position sensors sold in pairs?
A: Some engines, especially DOHC (Dual Overhead Camshaft) designs, might have two camshafts (one for intake, one for exhaust) and thus require two camshaft position sensors. Selling them in pairs ensures you have all necessary sensors, or provides a convenient spare if your engine only uses one.
Wrapping Up
Choosing the right camshaft position sensor for your 2011 Hyundai Elantra doesn’t have to be a headache. Whether you prioritize a multi-pack, superior component quality, or a straightforward OEM replacement, one of these top 5 picks will surely get your Elantra running smoothly again. Remember to always double-check compatibility with your specific vehicle’s year, make, and model before purchasing. Happy driving!
