How much does it cost to replace a knock sensor on a Honda CRV?
The knock sensor replacement for a Honda CR-V typically runs about $125 to $500, with most drivers paying roughly $250 to $350 for a standard job at an independent shop. Dealerships tend to be higher.
The following details explain what influences that price, what you should expect from different service options, and how to approach getting a fair quote. The knock sensor helps the engine computer detect abnormal combustion, and a failure can trigger a check engine light or engine performance issues. Costs vary by engine type, sensor type, and the job’s accessibility, and additional costs may arise if related wiring or mounting hardware needs replacement.
Cost breakdown
Below is a breakdown of typical costs you might see when replacing a knock sensor on a CR-V.
- Parts: Knock sensor price depends on OEM vs aftermarket. OEM sensors are generally more expensive (roughly $60–$180 per sensor, depending on year and engine). Aftermarket sensors can be substantially cheaper (roughly $20–$100). Some CR-V models use a single knock sensor, while a few configurations may have two; pricing scales accordingly.
- Labor: Labor time is commonly 1 to 2 hours, depending on engine layout and accessibility. Labor rates vary by region and shop, typically around $75 to $150 per hour, which can place the labor portion around $75 to $300.
- Diagnostic/inspection fee: Some shops charge a diagnostic fee when you bring the car in with the check engine light or a related symptom. This is often $50 to $100, though many shops waive it if you proceed with the repair.
- Other potential costs: If the sensor replacement requires handling related components (such as wiring harness repairs, gasket/seal replacements, or additional mounting hardware), those items can add to the bill. Environment/ disposal fees or shop supplies may also apply.
- Taxes and fees: Local sales tax and possible environmental or disposal fees will affect the total price.
Prices can vary by region, labor market, and vehicle year. The numbers above reflect common ranges observed in the U.S. market for CR-Vs from various model years.
Factors that influence price and how to save
The following factors influence the final bill, and there are steps you can take to minimize the cost.
- Engine type and sensor accessibility: Newer CR-Vs with different engines may place the sensor in a harder-to-reach spot, increasing labor time.
- Parts choice: OEM knock sensors cost more but are built to exact specifications; aftermarket options save money but vary in quality and warranty.
- Shop choice and location: Dealerships typically charge higher labor rates than independent shops; shopping around can yield significant savings.
- Additional repairs: If wiring harness damage, mounting hardware, or related seals are required, expect extra labor and parts costs.
- Diagnostic vs service: Some shops include diagnostics in the repair price if you proceed with the service; others bill separately.
- DIY potential: If you have the tools and skill, replacing the sensor yourself can save labor costs, but ensure you follow the service manual and torque specs to avoid damage.
To minimize costs, gather quotes from multiple shops, ask for a parts-and-labor breakdown, and consider whether OEM or aftermarket parts are appropriate for your car. If you’re mechanically inclined, a do-it-yourself replacement can trim the total further—but only if you’re confident in the replacement procedures.
Summary
Replacing a knock sensor in a Honda CR-V is typically a mid-range repair in terms of cost, with total expense largely driven by parts selection (OEM vs aftermarket), labor time, and any related wiring or gasket work. Independent shops usually offer better pricing than dealerships, and shopping around for quotes can yield noticeable savings. Understanding whether your model uses one or more sensors and confirming what additional work might be needed will help you anticipate the final bill.
