لقد تم طلب القطع وتم تركيبها ولكن للأسف لمبة الماكينة مازالت تعمل وعند محاولة فك الحساس كان يدور في مكانه تكلفت كثيرا من اجل هذا .. لا انصح بشرائه

After my mechanic installed 2 factory knock sensors, and problem still existed. I ordered these, and light is off now. After 100 mile road trip to reset computer, it's still off!!!

I had a licensed mechanic install these sensors and they did not work. I have a 2002 Silverado 2500 6.0l I keep getting the low voltage on #2 code. Truck only has 180k KM. Not liking Chev engineers right about now, #2 was full of water.

I installed these in my 2005 Silverado about 18 months ago. I started getting codes indicating they were defective within a year. I finally replaced them with some AC Delco sensors. These came apart when trying to remove them. I had to break them both, remove the valley cover, then drill both stems out to remove them with an EZ-Out. Considerably cheaper than the real GM sensors, but definitely not worth the savings.
