I have had my 2005 Chevy Avalanche 1500 5.3L for many

Customer Question
I have had my...

I have had my 2005 Chevy Avalanche 1500 5.3L for many years.Several years ago error codes for knock sensor came on. Had both sensors replaced. about 150 miles later the codes came back, Had them replaced again plus a new harness. codes came back after about 150 miles.

Mechanic's Assistant: Which particular sensor are you asking about? And have any trouble codes been triggered?

What else could possibly be going on?

Mechanic's Assistant: Are you fixing your Avalanche 1500 yourself? What have you tried so far?

Check engine light comes on an my mechanic says the code says knock sensor is bad. That's all I know

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That's about it. The codes keep saying the knock sensor is bad but after replacing them 3 times now I doubt its really the knock sensors.
