Prices observed across major retailers and dealers in 2024–2026 typically fall in the ranges below: the sensor itself costs about $20–$180, and labor to install it usually runs $60–$250 depending on location and shop.
What the knock sensor does and why it matters
The knock sensor monitors engine detonation and feeds data to the engine control unit, which adjusts ignition timing to prevent detonation and potential engine damage. A faulty sensor can trigger a check engine light and reduce performance. For a 2007 Honda Accord, the exact sensor needed depends on the engine configuration (2.4L four-cylinder or V6), and some models may use more than one sensor. Price and availability can vary by engine type and supplier.
Cost of the sensor itself
Below are typical price ranges you’ll see for the sensor alone, depending on whether you buy an original Honda part, an aftermarket unit, or a used option.
- OEM Honda knock sensor (new): typically about $75–$160, with dealer prices sometimes higher.
- Aftermarket knock sensor (brands such as Bosch, Denso, Standard Motor Products): usually $20–$60.
- Used or remanufactured knock sensor: roughly $15–$50, though reliability can vary.
Prices can vary by engine code (2.4L vs. V6) and region, and not all suppliers stock every version of the sensor. Always verify compatibility with your car’s VIN.
OEM vs aftermarket vs used
Choosing between OEM, aftermarket, or used sensors affects not only price but reliability and warranty. OEM parts tend to fit the first time and usually come with a warranty. Aftermarket parts save money but vary in quality. Used units can be cheaper but carry higher risk of failure down the line.
Labor and installation costs
In addition to the part price, labor to replace a knock sensor can vary by shop, engine type, and location. The job is typically straightforward, but access and required torque can influence time and cost.
- Independent repair shop: roughly $60–$120 in labor, assuming about 0.5–1 hour at standard shop rates.
- Dealership: commonly $100–$200 in labor, sometimes more depending on region and warranty considerations.
- DIY option: you may save labor costs but must factor in tool costs and the risk of incorrect installation; time can range from 1–2 hours for a typical engine.
All-in, the total installed price typically ranges from about $100 to $380, depending on the sensor type and the labor rate in your area. Some shops may charge diagnostic fees if they verify fault codes or symptoms before replacement.
How to shop for the right part
To ensure you buy the correct knock sensor for a 2007 Honda Accord, confirm your engine code (2.4L or V6) and check the VIN or parts catalog. Compare part numbers across OEM and reputable aftermarket suppliers, and read customer reviews for reliability. If unsure, ask your mechanic to verify compatibility before purchase.
Summary
For a 2007 Honda Accord, knock sensor pricing varies by engine configuration and source. Expect the sensor itself to cost roughly $20–$180, with installation labor typically $60–$250 depending on location and shop type. OEM parts cost more but may offer stronger warranties, while aftermarket options save money with variable quality. Always verify compatibility with your VIN and get a firm estimate before proceeding. Check with a local Honda dealer and a few trusted auto parts retailers or independent shops for the most accurate, up-to-date pricing in your area.
