knock sensors again!

[Jon Chimpo]

Hey all,

a few weeks ago i got knock senspr codes pop up. i replaced both, along with the harness. my wife drove the tahoe for 2 weeks, and they came back yesterday.... Any ideas?

If you bought the Autozone brand thats the problem. You need to buy OEM sensors. I've had similar issues with knock off brands.

Always buy OEM, you spend more upfront but dont have to be changing out parts twice. My 2 cents

They were BWD or BDW came with a warranty on the parts.

just talked to my mechanic buddy, he said it could be in the wiring, or ground?
