You want to avoid most of the EGR valves out there. Most of them have a smaller opening which can cause you to get P1491 check engine light because the passage is too narrow.

I haven't tried this one but the valve passage looks to be the same as on the Insight, maybe this one works fine:

It's cheaper than the Dorman I referred to above.
Thanks! Can the EGR valve be tested? I prefer not to buy parts unless I know I need them.
