2012 Hyundai sonata crankshaft position sensor location
Where is the crankshaft sensor located on a Hyundai?
The location of the crankshaft position sensor on a Hyundai crankshaft can vary depending on the model. Here are a few examples:
- Hyundai Accent (2012-2018): The crankshaft position sensor is located next to the oil filter, on the side of the engine block. 2012 hyundai sonata hybrid crankshaft position sensor location
- Hyundai Tucson: The sensor is typically found near the crankshaft, on the side of the engine block.
- Hyundai Sonata (2.4 GDI engine): The sensor is located on the side of the engine block, near the transmission.
Do you need to reset computer after replacing crankshaft position sensor?
In most cases, it is a good idea to reset the vehicle’s computer (engine control module or ECM) after replacing the crankshaft position sensor to ensure it correctly recognizes the new sensor. This process is often referred to as a “relearn procedure.” Here’s a basic outline of what you might need to do:
Steps to Reset the Computer:
- Disconnect the Battery: – Turn off the ignition and disconnect the negative battery cable. – Wait for about 10-15 minutes to allow the ECM to reset.
- Reconnect the Battery: – Reconnect the negative battery cable.
- Start the Engine: – Start the engine and let it idle. The ECM will begin to relearn the new sensor’s position.
- Driving Cycle: – Let the engine warm up to its normal operating temperature. – Drive the vehicle at various speeds and loads. Try to include highway driving, city driving, and idling periods to provide a complete range of operating conditions.
- Check for Errors: – Use an OBD-II scanner to check for any error codes. If everything is working correctly, there should be no codes related to the crankshaft position sensor.
- Clear Codes (if necessary): – If the check engine light remains on or there are any error codes, use the OBD-II scanner to clear them.
This procedure helps the ECM properly synchronize the new sensor with the engine’s operation. If you’re unsure about the process or if the vehicle doesn’t run smoothly after the replacement, it might be a good idea to consult a professional mechanic.
How do I know if my camshaft sensor is bad or the crankshaft sensor?
Diagnosing whether your camshaft sensor or crankshaft sensor is faulty can be tricky, but there are some crankshaft position sensor symptoms for each:
Camshaft Position Sensor Issues:
- Engine Won’t Start: The engine may not start at all or have difficulty starting.
- Check Engine Light: The check engine light may come on with codes such as P0340, P0341, or P0342.
- Poor Engine Performance: You might notice rough idling, misfires, or hesitation during acceleration.
- Transmission Issues: The vehicle might go into limp mode or have shifting problems.
- Increased Fuel Consumption: Poor fuel efficiency can be a sign of a failing camshaft sensor.
Crankshaft Position Sensor Issues:
- Engine Stalling: The engine may stall while idling or at low speeds.
- Difficulty Starting: The engine might crank but not start, or it may start and then stall.
- Check Engine Light: The check engine light may illuminate with codes such as P0335, P0336, or P0339.
- Poor Acceleration: You might experience hesitation or a lack of power when accelerating.
- Engine Vibrations: The engine might run roughly or vibrate more than usual.
Diagnostic Steps:
- Use an OBD-II Scanner: Connect an OBD-II scanner to read any diagnostic trouble codes (DTCs). This can help identify whether the issue is with the camshaft or crankshaft sensor.
- Visual Inspection: Check the sensors and their wiring for any visible damage or loose connections.
- Test the Sensors: Use a multimeter to test the resistance and voltage of the sensors. Compare the readings to the specifications in your vehicle’s repair manual.
