Lexus ES350 Knock Sensor

The Lexus ES350 Knock Sensor protects the V6 engine by detecting harmful spark knock before it causes damage. Mounted on the block, the piezoelectric unit converts the vibration to an electrical signal for the powertrain control module, which immediately cuts ignition timing in small increments and then adjusts timing back when normal combustion resumes, maintaining power, fuel economy, and emissions. Throughout the production run, Lexus retained this vibration sensing concept, but earlier versions of the ES350 applied a single flat-response device whereas later versions received an enhanced and more precise design of twin-channel layout, which can set timing for each cylinder and interpret correct Knock Sensor signals faster. Each Knock Sensor sits deep in the engine valley and feeds data in a closed loop continuously, so the computer can hold timing right at the knock limit so the ES350 can run happily on lower octane fuel or in extreme heat. This Knock Sensor strategy also improves reliability and weight balance for the Lexus midsize sedan and adds to overall Lexus durability. If a Knock Sensor fails, a code is stored in the control unit, and it is forced to use conservative timing, causing the ES350 to feel sluggish until it is corrected.
