Standard Ignition KS270 sensor for the 1996-1999 BMW 318i 4-cylinder 1.9L and other vehicles detects engine knock vibration and sends a signal to the engine computer. The computer uses that signal to help adjust ignition timing.
- Every unit goes through an accelerometer-based vibration test
- Sensor output is monitored by an automated data acquisition system 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
Quick facts
- Part: Standard Ignition KS270 sensor
- Fits: 1996-1999 BMW 318i 4-cylinder 1.9L and other vehicles
- Condition: New
A failing knock sensor can show up as a check engine light, audible pinging or reduced power. A damaged plug or wire can look the same, so with the engine off and cool, look over the connector and wiring for cracks or corrosion before replacing the sensor. A shop can test the signal itself.
Fits
The 1996-1999 BMW 318is 4-cylinder 1.9L and the 1996-1999 BMW 318ti 4-cylinder 1.9L fit this knock sensor, and so do many other models. Open the "Vehicles it fits" section to find your exact model and engine.

Frequently Asked Questions
Does the Standard Ignition KS270 knock sensor fit a 1996-1999 BMW 318is 4-cylinder 1.9L?
Yes. Standard Ignition KS270 fits the 1996-1999 BMW 318is 4-cylinder 1.9L and the 1996-1999 BMW 318i 4-cylinder 1.9L. Open the "Vehicles it fits" section to find other models.
Are mounting bolts included with this knock sensor?
No. The Standard Ignition KS270 comes without mounting hardware, so plan on new bolts instead of reusing the old ones.
What knock frequency range does this sensor respond to?
This knock sensor responds to knock frequencies up to 1000 Hz, which covers shifts in engine knock frequency across a broad range of vehicle conditions.
How many terminals does the KS270 connector have?
The KS270 has one oval plug-in connector with six male bullet terminals. It mounts with a bolt.
Is each Standard Ignition KS270 knock sensor tested?
Yes. Every unit goes through an accelerometer-based vibration test, and during manufacturing an automated data acquisition system monitors the sensor's voltage output.
