* Labor costs: This is heavily dependent on your location and the shop you choose. Independent shops are generally cheaper than dealerships. Expect to pay anywhere from $50-$150+ in labor.
* Part cost: A knock sensor itself is relatively inexpensive, ranging from $20-$75 depending on whether you buy an OEM (Original Equipment Manufacturer) part or an aftermarket part. Aftermarket parts are usually cheaper, but OEM parts are sometimes preferred for reliability.
* Additional repairs: Sometimes, a knock sensor issue is related to other problems. If the mechanic finds additional damage (like damaged wiring, etc.), the total cost will increase significantly.
Therefore, a reasonable estimate for the total repair cost would be anywhere from $70 to $225 or more. It's best to get a few quotes from different mechanics in your area to get a more accurate estimate specific to your situation. Be sure to clearly state that you need a knock sensor replacement when getting quotes.
