Smile 1992 toyota camry dtc 52 and dtc 55

Our camry has two codes ,52 =knock sensor circuit and 55 = right knock sensor. My question is (do i have two faults, or just the right knock sensor fault causing the 52 code and thus the 55 code)
My next question , do the knock sensors really go bad?
Is the right knock sensor next to the firewall ?
Would it be wise to swap sensors to see if the problem moves with the sensor ?
Last Question is there a better way to find the info i seek on line, i did type the dtc's on yahoo but could not find the answers
Any help would be fantastic
I am new to posting so please forgive my online lingo or lack there of

thanks Randy

Knock sensors DO go bad.

Have to check on location, stand by.

Also could be bad wiring to knock sensor or bad connector.

Knock sensor info:


And good OBD info here:


And, no, I don't think I would bother swapping them to diagnose. I don't think they're very expensive and you can get them from any parts house.
