An ACDelco GM Original Equipment Ignition Knock (Detonation) Sensor monitors the engine for pinging or spark knock, and is a GM-recommended replacement for your vehicles original component. The sensor creates a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses this signal to adjust the ignition timing and air/fuel mixture. This original equipment ignition knock sensor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
This ACDelco ignition knock sensor fit my vehicle perfectly. I didn't have any trouble with the installation, and since swapping it out, I’ve noticed a smoother ride. Great OEM part for the price!

Not what I expected
I bought the ACDelco knock sensor to replace a faulty one, but I noticed that it didn’t seem to fix the problem. Maybe it's just my car, but I was hoping for better results. The sensor looks good, though.

Decent sensor but took a while to arrive
I ordered the ACDelco knock sensor and, while it functions well, the shipping took longer than expected. It works fine now; just wish the delivery had been quicker. The sensor itself seems solid and does its job.
