Location of EGR and IAC valves on 2.7L

Hello everyone,

I am going to be doing a spring tuneup of my Taco this April and want to check the EGR and IAC valves on the engine.

Does the 2.7L even have these parts on them? If so, where are they located?

Thanks,
James

 

No. There is no EGR Valve or Idle Air Control Valve on the 2012 2TR-FE 2.7 Liter Engine.

You may want to check the PCV on the rear of the valve cover on the passenger side. It is a screw in type.

 

Thanks! Correct me if I'm wrong, but should the PCV rattle when I shake it?

 

Yes. It acts as a check valve to allow flow from the valve cover to the intake and block flow in the other direction.

 

You mentioned that there is no idle air control valve on this engine. Is there something that takes its place that controls your power steering, accessories, etc? How do you check this?

 

I don't even know what you are asking here? The engine idle is computer controlled. There is no IAC Valve nor a EGR Valve,

What does that have to do with power steering and accessories?

 

Older cars have an idle air control valve so when someone is turning and puts a load on the engine via power steering, the IAC tells the computer to increase the power to compensate.

If the the 2TR doesn't have IAC, then how does the computer know when to increase power in situations like slow speed turning?

Hopefully that clarifies the question for you.

 

Engine control systems are much smarter than they used to be as evidenced by the ass load of sensors etc. Such as the AC System when it comes on it sends and Idle Up Signal to the ECU to initiate an increase in idle speed. With all of the sensors it is constantly adjusting for changing conditions.
