Prices for a Honda knock sensor typically range from about $40 to $180 for a new OEM part, with aftermarket sensors often $15 to $60. Labor to install can add roughly $100 to $250, depending on the shop and engine configuration.
Exact pricing varies by model, engine code, whether you buy original equipment (OE) from a dealer or aftermarket parts, and whether you replace just the sensor or related wiring. As with most car parts, availability and pricing can shift by region and supplier.
Typical price ranges by source
The following ranges reflect common prices from major retailers and Honda parts sources for 2024–2026. They illustrate how OE versus aftermarket options can differ in price.
- OEM Honda knock sensor from a dealership: typically about $60–$180, depending on engine and part number.
- OEM-quality knock sensor from independent Honda parts distributors: generally $40–$120.
- Aftermarket/third-party knock sensors: commonly $15–$60.
- Used or remanufactured sensors: roughly $10–$60, with higher risk of inconsistency.
Prices vary by source and model, so it pays to shop around. OEM parts cost more but offer guaranteed compatibility, while aftermarket options can save money if you confirm the correct sensor type for your engine.
Key factors that influence price
Several factors influence the final price you pay for a knock sensor.
- Engine family and model year — different Hondas use different sensor designs (2-wire vs 3-wire) and part numbers.
- OEM vs aftermarket brand — OEM parts are typically pricier but guaranteed to match your vehicle.
- New vs used or remanufactured — used/remanufactured parts are cheaper but may have shorter lifespans.
- Where you buy — dealer prices differ from online retailers and local auto parts stores.
- Additional hardware or labor — installation may require wiring harness checks, gaskets, or thread repairs, affecting total cost.
- Geographic region and shipping/taxes — final checkout price can vary by location.
In short, the price you see will depend on your specific vehicle and the sourcing channel. Always verify compatibility with your VIN and engine code before purchasing.
How to find the exact current price for your Honda
To lock in an exact price for your vehicle, gather your car’s VIN and engine code, then compare options across several retailers. Use the following steps to confirm compatibility and price.
- Check OEM Honda parts websites or your local dealership for the precise part number and price for your engine.
- Compare prices at major auto parts stores (AutoZone, O'Reilly, Advance Auto) and reputable online marketplaces.
- Look up the part on RockAuto or similar catalogs to view multiple brands and price points for your exact engine.
- Double-check compatibility by matching the part number to your engine code and VIN; confirm whether a wiring harness or sealant is recommended.
- Calculate total costs, including shipping, taxes, and any required installation labor or tools.
- If possible, contact a parts specialist to verify the correct sensor type for your model and year.
With the exact price in hand, you can choose between OEM reliability and aftermarket savings, and plan for installation if you’re not doing it yourself.
