2000 frontier crew cab fuel temperature sensor

[eliasj]

Let's try it with the full model in the title.

My engine light is on and did the OBDII test and got the following codes:

P0180 Fuel temperature sensor A circuit malfunctionP0325 Knock sensor malfunction circuit 1 bank 1

I have read that the first code could be causing the second one, but here is my problem:

The part "fuel temperature sensor" cannot be found in any online catalog. Could it be part of something else like the fuel pressure regulator or the fuel pump?

Where are the temperature sensor and knock sensor located? are they under the air intake manifold ? I cannot find them.

any help would be appreciated.
