Knock Sensor Kit & Harness Assembly - Front, Fits Lexus GS300 GS400 RX300 LS400

About This Product

Is your Lexus (GS300, GS400, RX300, or LS400) throwing a check engine light for knock sensor issues? This complete kit from LJT is the fix. It includes everything: TWO new knock sensors AND the connecting wiring harness assembly, all for the front location. Part number LJT10287707, also replaces common OEM numbers like 8961512040. Comes with a 12-month warranty. Installing both sensors and the harness at the same time is smart – it prevents future failures of the old brittle wiring. This is a common problem on these Toyota/Lexus V8 engines, causing poor performance and mileage. The kit is brand new, and tackling this job can save you a ton compared to a dealer repair. Get your smooth, powerful ride back and clear that annoying light for good. A must-have for any DIY mechanic or shop working on these classic Lexus models.
