Review on 🚗 High-Quality Dual Knock Sensors with Wiring Harness Kit for GM Vehicles - Replace # 12601822 12589867 917-033 by Matthew Allen

It's complete junk, put them both in and had a short drive and what do you know check the engine light is on and scan it and there are codes for every knock sensor i bought brand new GM and i tried to pull these new ones out and the tops just twisted and i couldn't pull them out and then i used a chisel and hit the edge all the way around and it still worked not and still turned like that. I tried again and then because they are so cheap the sensor bent and broke off in the block and I tried to be extra careful with the second one and he is Broke so I had to take a valley cover. Turn off the sensor and pierce it and use the easy way to get the rest out and it didn't work most of the time but it did. These are all useless and cheap and will break trying to pull them back when needed because they don't work at all.
