Location of Secondary Air Pump

A couple of questions after getting the error code P0418. First, where is/are the secondary air injection pumps located and where are the relays? Also, which side is A and which is B? I am unable to find anything online.

If I understand correctly there are separate pumps on each side.

Thank you in advance for any input.

 

Isn't there something behind the intake manifold?

 

The AIPs are located on the passenger side hidden behind the plastic wheel well liner, upper front. Remove the liner and you will see them.

 

You will find the SAIS Air Pumps located in the Passenger Side Fender well on both the 5.7L and 4.6L '15 Tundras. The P0418 is an Air Pump SAIS fault code.

For reference, the SAIS Air Switching Valves on the 5.7L are located on the backside of the engine block dead center. On the 4.6L the Air Switching Valves are located on each side of the engine, one passenger side and the other driver side.
