Standard Ignition KS357 sensor for the 2013-2019 BMW 640i Gran Coupe 6-cylinder 3.0L and other vehicles picks up engine knock vibration and sends a voltage signal to the engine computer. The computer uses that signal to adjust for knock.
- Every unit goes through an accelerometer vibration test for trouble-free operation
- An automated data acquisition system monitors sensor output during manufacturing for the right voltage at the specified frequency range
- Responds to knock frequencies up to 1000 Hz, so it follows shifts in engine knock frequency across a broad range of vehicle conditions
Quick facts
- Part: Standard Ignition KS357 sensor
- Fits: 2013-2019 BMW 640i Gran Coupe 6-cylinder 3.0L and other vehicles
A check engine light, reduced power or engine pinging can all go with a failing sensor. These signs alone do not prove the sensor is the problem, since damaged wiring or a loose connector can cause them too. This listing is one sensor, and these engines take one.
Fits
This sensor is listed for a wide range of BMW models, including the 2014-2019 BMW 640i xDrive Gran Coupe 6-cylinder 3.0L and the 2016-2019 BMW M2 6-cylinder 3.0L.
