Can anyone give me some tips on testing the knock sensors? (92 Camry 3VZFE)

Thanks!

continuity....if there isn't any, they're blown :

So if there is no continuity between any of the contacts in the connector that goes to the sensors, they are both shot.

Can they be wrecked by having a bad rod bearing?

to the best of my knowledge, yes....


and maybe depends on how bad it was, I suppose.....but that's rather hard to say

If the 3vz has been taken care of the bottom end will last for a very long time, knock sensors go out with age, mine have lasted this long (92 3vz-fe right about to turn 170k miles) with no trouble, but if they go I wont be too suprised. Id replace both to save on labor, sucks getting in there and replacing on just to leave an old one in there next to it
