How Much Does It Cost to Replace a Camshaft Position Sensor on a Hyundai Sonata?

For most Hyundai Sonata models in the United States, replacing a camshaft position sensor typically costs between $180 and $420 total, including parts and labor, with DIY replacement often landing between $40 and $140 for parts alone. The exact price depends on model year, engine type, location and whether you use a dealership, independent shop or do it yourself.

What the Camshaft Position Sensor Does — and Why It Matters

The camshaft position sensor is a small but critical electronic component that helps your Sonata’s engine computer determine the exact position of the camshaft. This information is used to time fuel injection and ignition precisely, which directly affects performance, fuel economy and emissions.

Common Symptoms of a Failing Camshaft Position Sensor

Understanding the warning signs can help you budget and plan for the replacement cost before the car becomes undriveable.

  • Check Engine Light illuminated (often with codes like P0340, P0341, P0345 or related camshaft sensor codes)
  • Hard starting or no-start conditions, especially when the engine is hot
  • Rough idle, engine misfires or hesitation during acceleration
  • Reduced power or the engine going into “limp” or fail-safe mode
  • Poor fuel economy and inconsistent engine performance

When these symptoms appear together, especially with relevant diagnostic codes, mechanics often confirm a failing camshaft position sensor before recommending replacement.

Typical Replacement Cost Range for a Hyundai Sonata

While prices can vary widely, most Hyundai Sonata owners can expect a mid-range repair bill compared with other engine-related work.

Overall Cost Breakdown

The total cost depends on where you go and which parts you choose. Below is a general overview for recent model years (roughly 2011–2023) in the U.S.

  • Dealership service: About $250–$420 total
  • Independent repair shop: About $180–$350 total
  • Mobile mechanic services (where available): Often $200–$350 total
  • DIY (do it yourself): About $40–$140 for the sensor, plus any tools you may need

These ranges assume a standard replacement of a single camshaft position sensor without major complications or additional issues, such as damaged wiring or related engine problems.

Parts Cost: OEM vs Aftermarket

The sensor itself is relatively affordable, but prices differ depending on whether you choose Hyundai OEM or aftermarket brands.

The following points outline typical parts pricing for a Sonata camshaft position sensor, based on current U.S. retail and online listings for many 2011–2023 models.

  • OEM Hyundai sensor: Approximately $80–$160
  • High-quality aftermarket (e.g., Delphi, Denso, Bosch): Approximately $50–$120
  • Budget aftermarket brands: Approximately $30–$60 (sometimes less in online marketplaces)
  • Multiple sensors (some engines): If your engine has more than one camshaft sensor and both are replaced, parts costs can double

While cheaper sensors may be tempting, many mechanics recommend OEM or reputable aftermarket brands to reduce the risk of premature failure or inconsistent readings.

Labor Cost and Time

Labor is typically the larger part of the bill at a shop, but for this job, it is still modest compared with many other engine repairs.

Here is how labor usually breaks down for a camshaft position sensor on a Hyundai Sonata.

  • Book labor time: Around 0.5 to 1.0 hours for most model years
  • Typical labor rate (independent shop): $90–$150 per hour in many U.S. regions
  • Typical labor rate (dealership): $130–$220 per hour, depending on the metro area
  • Expected labor cost: Roughly $80–$220, assuming no additional diagnosis or wiring repair is needed

Because access to the sensor is usually straightforward on the Sonata, labor times remain relatively low, keeping the total bill more predictable.

How Model Year and Engine Type Affect Price

Not all Hyundai Sonatas are built the same. Costs can vary by generation and engine configuration, especially between naturally aspirated and turbocharged engines or hybrid versions.

Approximate Costs by Sonata Generation (U.S. Market)

The following estimates use typical U.S. repair rates and part availability as of late 2024. Exact prices in your area may differ, but these ranges offer a realistic benchmark.

  • 2011–2014 Sonata (YF, 2.4L / 2.0T): About $180–$350 total at an independent shop; sensors are widely available and generally inexpensive.
  • 2015–2019 Sonata (LF / LF Hybrid): About $200–$380 total; hybrids and turbo engines can be toward the higher end due to part pricing.
  • 2020–2024 Sonata (DN8, including 1.6T and hybrid): About $230–$420 total, as newer OEM parts and dealer labor tend to cost more; aftermarket options are still maturing for the latest models.
  • Older models (pre-2011): Often similar or slightly cheaper, depending on part availability; some older OEM parts may actually cost more if they are less common.

These generation-based estimates can serve as a starting point, but confirming your specific VIN and engine code with a parts supplier or repair shop will give the most accurate quote.

Additional Costs That Can Affect the Final Bill

While a simple sensor swap is usually straightforward, extra work can add to the total cost if other issues are found during diagnosis.

Diagnosis and Related Repairs

Sometimes the sensor is not the root cause, or additional work is required to ensure a lasting repair.

Below are common add-on items that can influence your final cost.

  • Diagnostic fee: Many shops charge $100–$180 to scan codes and confirm the fault before replacing parts; some waive or reduce this if you approve the repair.
  • Wiring or connector repair: If the problem is frayed wires, corrosion or a damaged connector, you might pay an additional $50–$250 depending on the extent of repair.
  • Multiple sensors: Some engines have separate intake and exhaust camshaft sensors; if both are replaced as a preventive measure, parts and labor may roughly double.
  • ECU or timing issues: In rare cases, the check-engine light points to the sensor, but the real issue is a timing problem or a failing engine control unit, which can significantly increase costs.

Because of these variables, most reputable shops will scan the vehicle and verify the fault path before replacing the sensor, helping avoid unnecessary part swaps.

DIY vs. Professional Replacement

Replacing a camshaft position sensor on a Sonata can be a feasible DIY project for someone comfortable with basic automotive work, but it is not ideal for everyone.

DIY Considerations

For owners who like to turn their own wrenches, the job is usually manageable with common tools and basic caution.

The following points outline what a typical DIYer should expect.

  • Skill level: Beginner to intermediate; involves locating the sensor, disconnecting the battery, unplugging a connector and removing a small bolt.
  • Time required: About 20–60 minutes for someone familiar with basic engine-bay work.
  • Tools needed: Basic socket set, possibly a small extension, and sometimes a Torx or Allen bit depending on sensor design.
  • Risks: Damaging the connector, overtightening the bolt, or misdiagnosing the fault (replacing the sensor when the real problem is wiring or engine timing).

DIY can significantly cut costs, but it is important to verify the fault with an OBD-II scan tool or have a professional diagnosis before buying parts.

Advantages of Using a Professional Mechanic

For many owners, paying a shop for this repair is about peace of mind, speed and warranty coverage.

Here are the key benefits of professional service for this job.

  • Accurate diagnosis: Technicians can confirm whether the sensor, wiring or another component is actually to blame.
  • Warranty on parts and labor: Many shops offer 12-month/12,000-mile or better warranties on the work performed.
  • Access to OEM parts: Dealerships and some independents can source the exact Hyundai-branded sensor quickly.
  • Time savings: The job is often completed within an hour or in the same day, even during a routine service visit.

For newer or still-financed vehicles, using a qualified shop may also help maintain documentation that supports warranty or goodwill claims later.

How to Get an Accurate Quote for Your Sonata

Because of the variables involved, the most reliable way to know the cost is to request quotes using your specific vehicle details and local rates.

Steps to Estimate Your Exact Replacement Cost

By following a few straightforward steps, you can quickly narrow down a realistic budget for your repair.

  1. Gather your vehicle details: Note the model year, engine size (e.g., 2.4L, 2.5L, 1.6T, hybrid), mileage and VIN if available.
  2. Call at least two shops: Contact a Hyundai dealership and an independent shop for written estimates including parts, labor and diagnostic fees.
  3. Ask about part type: Confirm whether the quote is for OEM or aftermarket and whether there is a warranty on the sensor.
  4. Check online parts prices: Compare shop quotes with reputable online retailers to understand the markup and potential DIY savings.
  5. Factor in taxes and fees: Sales tax, environmental fees or shop charges can add 5–15% to the pre-tax estimate.

Taking these steps gives you a clear, realistic number before you book an appointment, and can help you choose between dealership, independent shop or DIY repair.

Summary

Replacing a camshaft position sensor on a Hyundai Sonata is generally a moderate-cost repair, with most owners paying $180–$420 at a professional shop and $40–$140 if doing the work themselves. Parts typically run from $50 to $160 depending on whether you choose OEM or aftermarket, while labor is usually 0.5–1.0 hours, translating to around $80–$220 in most U.S. markets. Final costs vary by model year, engine type, local labor rates and any additional wiring or diagnostic work needed. For precise pricing, collecting a couple of local quotes based on your VIN is the most reliable way to know what you will actually pay.
