I have read a lot on issues with Knock Sensor P0325 and P0330 issues here. The question i have is where is the knock sensor located on the 2.7 l engine. My code says P0325 knock sensor 1 circuit malfunction or that it may be faulty. After reading a bunch of threads here, most folks say that the sensors seldom go bad and that it is the wire harness that may be bad. Pictures would really help to locate the sensor and how hard is it to change the wire harness.
thanks for all your help in advance.

 

how many miles do you have?
I have the 2000 toyota 4runner 2.7

 

2wd, Auto with 91,000 miles.

 

is it running rough or its just the code that worries you?

 

It is just the code. It runs fine.

 

I have a code popping a p0325 for the knock sensor. I figure the sensor is still good (possibly loose?) and that the wires are the problem...

My only question is.... WHERE is the dang thing? I have a generic maintenance book so its pictures are for a broad range of vehicles (including my Tacoma).

Any advice?

1995 Toyota Tacoma ODO 228000 miles. The vehicle is not running well but still runs.

 

the knock sensor is located just above the fuel filter under the intake manifold

the check for it is to remove it and check for continuity between the terminal and the body, there should be no continuity
