Hello all,
I was wondering if any of you could help me find a knock sensor on my 03 chevy silverado, 5.3 liter Ls edition.
A bad emmisions light came on my dash about a month ago, prior to that it would somtimes come on for a brief time then shut off. But a month ago it came on for good. I just ignored it but finally hooked it up to the computer and it said i had a bad knock sensor. A fellow Ag mechanic told me he had to replace his too, he told me there was one on both sides of the engine block, but for the life of me i can not find it. I looked it up on the enternet and it said it was just above the oil pan, or right by the bell housing.
Can you tell me what this sensor does? I was told it will fail and just tell your computer it is getting bad emissions, but what is the piont of calling it a knock sensor? If it goes out will your MPG get worse? I have noticed my MPG falling but didnt know if this was the cause.
Thanks for any and all help.
