Knock Sensor Replacement Cost
Get an Estimate
RepairPrice Estimates are based on the estimated time for the repair, labor rates charged by trained automotive professionals, and prices for quality parts.
These estimates are designed to show a range of fair prices, instead of a single price, because there is more than one part that is appropriate to use in each repair, and more than a single mechanic who is qualified to do the repair.
Each estimate is customized for your vehicle and geographic area. Estimates exclude applicable taxes, diagnostic charges and disposal fees.

Only use factory OEM knock sensors and be sure to check for any relevant Technical Service Bulletins (TSBs), necessary software updates, and re-calibration procedures.
When a knock sensor fails, the engine may lack power, have poor acceleration, ping or knock on acceleration, and get poor fuel economy.
The Check Engine Light may illuminate with a fault code set for one or more knock sensors.
A knock sensor code isn't always triggered by a defective knock sensor. It can be triggered by a malfunctioning EGR system, a lean air-to-fuel ratio, worn ignition components, a cooling system problem, or an engine mechanical problem.
