Camshaft Position Sensor Overview

The camshaft position sensor is a crucial component in the 2013 Hyundai Elantra's engine management system. It monitors the position and rotational speed of the camshaft, providing vital information to the engine control unit (ECU) for proper timing and fuel injection.

Sensor Location

The 2013 Hyundai Elantra has two camshaft position sensors:

1. Intake Camshaft Position Sensor: Located on the top of the engine, near the valve cover on the intake side.

2. Exhaust Camshaft Position Sensor: Positioned on the rear of the engine, also near the valve cover but on the exhaust side.

To access these sensors, you'll need to remove the engine cover, which is held in place by four rubber grommets.

Identifying the Sensors

  • The sensors are small, cylindrical devices with an electrical connector.
  • They are typically secured with a 10mm bolt.
  • Look for wiring harnesses leading to the top and rear of the engine.

Replacement Process

1. Disconnect the negative battery terminal.

2. Remove the engine cover by pulling it straight up.

3. Locate the sensor you need to replace.

4. Unplug the electrical connector (press the tab and pull).

5. Remove the 10mm bolt securing the sensor.

6. Carefully pull out the old sensor.

7. Insert the new sensor, ensuring it's fully seated.

8. Reinstall the bolt and reconnect the wiring harness.

9. Replace the engine cover and reconnect the battery.

Important Considerations

  • Always use OEM or high-quality aftermarket sensors to ensure proper functionality.
  • Be careful not to damage the sensor's O-ring during installation.
  • Clear any related error codes after replacement using an OBD-II scanner.

Common Symptoms of Faulty Sensors

  • Check Engine Light illumination
  • Engine misfires or rough idle
  • Difficulty starting the engine
  • Reduced fuel efficiency
