Knock Sensor (KS)
WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2020 Lincoln Navigator, 2020 Lincoln Nautilus, 2020 Lincoln MKZ, 2020 Lincoln Corsair, and 2020 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
The KS is a tuned accelerometer on the engine which converts engine vibration to an electrical signal. The PCM uses this signal to determine the presence of engine knock and to retard spark timing.
Typical locations for the KS:
- KS11 - bank 1, sensor 1 (near cylinder 1/2)
- KS12 - bank 1, sensor 2 (near cylinder 3/4)
- KS21 - bank 2, sensor 1 (near cylinder 4/5 on a V engine)
- KS22 - bank 2, sensor 2 (near cylinder 6/8 on a V engine)
