Default Po332

I'm getting a PO 332 code. I recently swapped the engine out with a used junkyard motor. Still getting the same code. Knock sensor 2 signal short/low. Should I just replace the knock sensor 2? If so, where can I find it? 2002 3.8L 8th digit K.

Thanks!

Click on that link. In that message there are more links and those should show you where they are located.

Default Which is which?

Since it has two and my error code says it is number two.....which knock sensor is technically number two? I didn't see that in the links.

Thanks!

I believe number 2 is the rear.

The rear has about an 18" extension on it. Usually it'll be sitting over the diff in the transmission for the connection.
