'97 Avalon 1410 and 1411 code errors

[97avalonga705]

Can anyone send me pictures of where the ERG valves are located so I can check the connections based on what I read in a posted thread. Here is what I found searching the forum regarding the error messages. I just need assistance in locating where to check via pics. Any help is appreciated.
P1410 EGR Barometric Pressure Sensor VREF Voltage
P1411 Secondary Air is not being diverted

It should be right next to the throttle body by the intake plenum, it is that round thing with a sensor seating on top and a vacuum hose right next to the sensor. You probably just need a EGR position sensor.

N.E.O.

Will I have to remove a lot to get to the EGR position sensor because I looked at the part at Advanced Auto and Auto Zone, it appears to be a simple piece?

Just unplug the connector and the screws, that's it.

Thanks for the tip, when I replace it, I will let you know how it goes. I will probably try to clean the EGR valve as well.
