A Guide to the Engine Crankshaft Position Sensor for the 2005-2010 Hyundai Tucson
Experiencing stalling or a no-start situation? Your crankshaft position sensor might be the culprit.
- A failing crankshaft sensor is a common issue on 2005-2010 Tucsons, often causing no-start or stalling problems.
- The Check Engine Light with code P0335 is the most common indicator of a bad sensor.
- For this critical part, choose a reputable aftermarket brand like Delphi, NGK/NTK, or Standard Motor Products for reliability.
- Replacement is possible for a DIYer with basic tools, but access on the V6 engine is tight and requires working from underneath the vehicle.
Understanding a Common Failure on the First-Generation Tucson
If you own a 2005-2010 Hyundai Tucson, you might eventually face an issue with the engine crankshaft position sensor. It's a known part to fail over time, often due to years of exposure to engine heat. This can cause the sensor's wiring and plastic to become brittle and crack, leading to a poor signal. When this happens, your Tucson can experience a range of frustrating and sometimes dangerous symptoms.
Is it an OEM or Aftermarket Part for Your Tucson?
When it's time to replace the crankshaft position sensor, you have a choice between Original Equipment Manufacturer (OEM) parts from a Hyundai dealer and aftermarket parts. For a critical sensor like this, quality matters. Some mechanics and owners report that very cheap, no-name aftermarket sensors can be unreliable or fail quickly, sometimes right out of the box. However, reputable aftermarket brands often supply the original parts to Hyundai or produce parts that meet or exceed OEM standards. Brands like Delphi, NGK (under their NTK line), and Standard Motor Products (SMP) have a strong reputation for producing quality sensors. Choosing a well-regarded aftermarket brand can offer OEM-level quality at a more affordable price.
A Note on Brand Tiers
Not all aftermarket parts are created equal. For a critical component like the crankshaft position sensor, it's wise to avoid the lowest-priced, unbranded options. Stick to established brands for better reliability.
- Premium Brands (Often OEM suppliers): Delphi, NGK/NTK, Hitachi. These brands are known for high-quality engineering and testing.
- Quality Mid-Range Brands: Standard Motor Products (SMP), Walker Products, Beck Arnley. These are trusted names in the aftermarket that offer a good balance of price and quality.
- Economy/Value Brands: Dorman, Spectra, and others. While often more affordable, quality can sometimes be inconsistent. Some owners have success, while others report premature failures.
Replacement Cost
The cost to replace the crankshaft position sensor can vary. The part itself is not very expensive, but labor can add up if you take it to a shop, as accessing the sensor can be time-consuming.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Sensor | $17 - $91 |
| New OEM Sensor | $90 - $210 |
| Shop Labor | $150 - $300 |
| Total (DIY) | $17 - $91 |
| Total (Shop) | $167 - $391 |
Installation Tips for the V6 Engine
On the 2.7L V6 model, the sensor is located on the back of the engine block, near the transmission bellhousing and above the starter. Access is from underneath the vehicle. You will likely need to remove a small heat shield to get to the sensor, which is held in by a single 10mm bolt. The space is tight, so having tools like a wobble socket extension can be very helpful. Always disconnect the battery before starting this repair.
Frequently Asked Questions
Are there any recalls for the crankshaft sensor on this Tucson?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any recalls specifically for the crankshaft position sensor on the 2005-2010 Hyundai Tucson. There were recalls for other items like the stop lamp switch and electronic stability control system.
What's the difference between the sensor for the 2.0L and 2.7L engines?
The 2.0L 4-cylinder and 2.7L V6 engines use different crankshaft position sensors. They are not interchangeable. It is crucial to order the correct part for your specific engine to ensure proper fit and function. Always verify the part fitment for your vehicle's year and engine size before purchasing.
What is a P0335 trouble code?
P0335 is a generic OBD-II trouble code that means "Crankshaft Position Sensor 'A' Circuit Malfunction." This is the most common code you will see when the sensor fails. It means the engine's computer has lost the signal from the sensor or the signal is incorrect. This can be caused by a bad sensor, damaged wiring, or a problem with the sensor's connector.
Can a bad crankshaft sensor cause the engine to misfire?
Yes. A faulty sensor can send incorrect timing information to the engine computer. This can disrupt the timing of the spark plugs and fuel injectors, leading to engine misfires, rough idling, and a feeling of vibration.
