2002 Chevy: check engine light..332 for knock sensors..wiring harness

Customer Question

I have a 2002 Chevy Silverado with a check engine light on. The code is 332 for knock sensors. Both sensors have been replaced and also the wiring harness for them. The light went out briefly but then came back on. Do you have any suggestions what to do next. Any help appreciated.

2002 Chevrolet Silverado 1500

I looked it up for a 1500, if you have a different model let me know. Probably the same code though. Did you check the fuse for the knock sensors? Below is the test procedures and wiring diagram.
