knock sensor for my 04 2RZFE

I need to replace my knock sensor. They are crazy expensive, at least what I can find. What is a good source?

 

It needs to be replaced why?

Inexpensive parts on Toyotas cause more problems than they fix, especially when it comes to engine electronics.

It shows 2 different sensors. Are the 2 of them? Do I need both?
I put in my VIN, so I believe the selection was right.

 

What code are you getting? I’m not real familiar with the 2RZFE but a quick search indicates one knock sensor.

Have you checked your wiring for rodent damage?

 

The wiring is good. The only code is PO325 knock sensor.

 

I don’t know why Toyota is showing two knock sensors.

Everything I have read says it’s located under the intake manifold.

 

I could be wrong on that.
What about coolant temp sending unit. Is there one, or 2? I am awhear of one on the head against the firewall, but is there another?

 

There's one for the EFI (sensor) and one for the temperature gauge (sending unit). I think the one for the gauge is in the thermostat housing.

 

Have you installed the knock sensor you ordered in this thread?
