That previa has a central engine, so all engine work requires you take out driver and or front passenger seat out.

The EGR placement is here >>

near the bottom of the page.
Good luck

SOURCE: 1992 Toyota Previa van,Oil dripping onto exhaust manifold, replace head gasket? need a free manual!

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

SOURCE: Toyota Corolla DX 97 Engine Light EGR valve PLEASE HELP

You can try cleaning the EGR valve and passages with Seafoam. A bottle costs just a few dollars at any auto parts store or discount store. With the engine running, squirt/spray it in through the brake booster hose, or through the PCV hose. This will cause smoke to come out the exhaust. This is normal and will disappear after a few minutes. If Seafoam does not do the trick, then you can still disassemble the EGR valve from the throttle body and clean it with throttle body cleaner.

SOURCE: how to replace EGR valve in 1996 toyota camry

It is simple. It looks like a little flying saucer or pancake and it is in the rear of the engine on top near windshield.There are two hoses that plug into it from the exhaust, and one coming out, and one on bottom (total of 4). You can just unplug the hoses and replace them easily.

SOURCE: oil level light stays blinking on toyota previa

most of these models have 2 oil lights.The red one is oil pressure,if flashing or on when engine is running,it is usually serious.check oil level,but usually caused by blocked pickup screen(a common toyota fault) when services aren't done.The orange oil light is tripped by an oil level sensor on the side of the sump when the oil level is low.If the oil level is ok,note this is a common fault especially if oil changes have been missed,and/or a petrol engine oil used and sludge builds up,sometimes using an additive for flushing prior to oil change can help,but may not work on 1st oil change.

Check engine light only comes on when I press the gas in my 1991 Toyota Preiva,changed the O2 sensors and it's still on

Do you know what trouble code the Previa is throwing?
You may want to check the little 1/2 inch diameter passage in the throttle body that connects to the EGR valve. If that passage gets clogged (and it usually does), It'll throw a check engine light. I was having a similar problem and found that this passage was completely blocked with carbon deposits. You can clean it out with a small screwdriver and a shopvac.
