Driving around with knock sensor fault code

Picking up my father's 2002 Tundra with the 4.7 next week to take over and found out he has been driving it around for 2 years with the knock sensor faulty code/check engine light... Will there be any damage as a result? I do not want to walk into an issue.... Plan on replacing it as soon as I pick it up.
Thanks!

 

Sweet Deal on the hand me down 1st Gen.

Will there be damage? Hard to tell.

Here is how I look at Sensors: They are there for a reason so you should replace them. There are two. They are near the Starter. All three of these items are under the Manifold and take some work getting to them. I suggest replacing all 3 items at the same time.

The Knock Sensors cost about $170 each from the Stealership and you can buy a Reman’d Starter (Heavy Duty Version 2.0kV) for about $130 from Denso Online.

Assuming your truck is 4.7L.

 

Yes, 4.7...

 

Getter dun!

 

I drove around for quite a while with mine on. No harm in it;just shitty mileage. Take a look between the intake runners at the engine valley and see if you can see the wires or if theres a rat's nest in there.
