1998 Tacoma 3.4L V6 TPS replacement?

I currently own a 1998 tacoma SR5 3.4L V6 with manual transmission. The check engine light has been on for some time now, and the code is for a throttle position sensor. It's never been replaced in the time I've owned the truck so i'm sure its been on there since it came out of the factory.

My question is, do I have to adjust the TPS once I put the new one on, or is it pretty much plug and play? I have heard that it does need adjusted, but I have also heard that it does not need adjusted. If it does need adjusted what is the process? It seems like a quick simple fix, but I want to make sure before I take it off.
Thanks

 

I have never changed one on a taco but have changed a few on other things. You will you will need a multimeter and the spec for voltage or resistance from the service manual. Install looks straight forward

 

Ok thanks for the info.

The check engine code is P0120 (TP sensor or switch A circuit malfunction). I'm not really noticing any symptoms of a bad TPS other than reduced gas mileage, though it does seem like the truck has less power lately, but i've also got a Knock sensor code P0330.

 

Knock code will essentially put the truck in limp mode, safe timing, because it cannot sense knock at advanced timing. safe timing will make a lot less power and fuel mileage will be poor. Time for new knock sensors

 

Yeah that's what I figured. Are the knock sensors hard to get to?

 

unfortunately on the V6 they're under all of the intake pieces
