What does it take to get rid of all the junk sensors on a toy 3.0? is there a harness specifically made to eliminate these?
attempting to rebuild one and can't believe all the wires in here
 
You get rid of all the sensors it won't run when you're done. They are there to tell the computer what's going on in the engine.
 
its not junk its called fuel injection, you could certianly clean up some vacuum lines on it, but the wires well they are kinda of needed, inputs for the ECU to manage the fuel system.

take EGR off and secondary air that eliminates about 6 vacuum lines and alot of space on the passengerside the VSV's you can eliminate as they control the sec air and egr as well as evap control, the EGR temp sensor wire that not all 3.0's use only the later ones, you could eliminate the 4wd light wire but really that is very simple engine with limited wiring. besides the 3-4 vsv on the pass side everything is critical to the engine management system.
 
As previously mentioned, if you plan to run off the computer, you got to keep the sensors.

Or, adapt a carburetor to the lower intake section and with a 5 speed behind it, you can relive the 60's.
 
Thanks, anything and every bit helps, what about sensors like exaust by the catalytic converter or the air cleaner, anyway to eliminate those? it is a late 95 3.0 from a 4runner. is there any software i can load and plug a laptop into this thing and eliminate anything?
 
Those sensors in the exhaust are the oxygen sensors. They tell the computer how the combustion process went and what to do on the the next one. The one by the air filter is the air mass meter. It tells the computer how much air is coming into the engine so it can add the right amount of fuel. Gotta have both of those. Sorry. Whatcha building? A buggy or just rebuilding the engine to put back in a existing vehicle? Your best bet is to just label everything as you take it apart and plug it back in on reassembly.
 
A bit of both but probably a futile attempt to place a 95 3.0 in a buggy frame. Motor blew a freeze plug or something that was squirting water from behind the cross over exaust pipe and so it wasn’t a total loss I was going to place it in a buggy.
 
If you want to loose the sensors.....then just junk the whole motor because it's the worst engine toyota ever produced
 
still a toyota 3.0

my friends mom has a camry with the 3.0 and they still haven't had a problem with 213k on it
