Sick to death over my izusu trooper egr valve & check engine light

Just bought a new egr valve from auto zone and my mechanically inclined husband put it on and the check engine light is still on!!!

What's the deal here? We already tried cleaning it first, several times. Finally bought a new one and it still isn't working. Can't get my past due inspection sticker because of the new emissions law - THANKS OBAMA - and am wondering what the hell we're supposed to do now!

Anyone know anything about this and how to successfully fix this??

Thanks for help!!

Welcome to the forums

Basic question, I know, but what does the code in the computer say?

If the problem was the EGR, the check light would not immediately go out on it's own after replacement. Sometimes the fault codes need to be removed by a scanner, but also they are reset after a certain number of starts and warm ups. If you did solve the real issue for the fault codes being the EGR you may see the light go out in the next 2 or 3 days of driving.

Further to the comments made by DianaTX, does anyone know if there are new emission rules around yearly inspections mandated by Washington? I thought they were all state controlled and managed within each county for those states that even require them along with yearly safety checks. That at least has been my experience in Texas.

Not that I'm the expert but I'm pretty sure they are state requirements, not country.
In PA, we've had that emissions testing ever since I can remember, but only after so many miles of driving and some other "only ifs". Seems like forever, and certainly a lot longer than Obama.

In Ohio, the state mandates the emission inspections on a county by county basis. We were required to get annual inspections in my county for a number of years. We finally got "green" enough for the state and they dropped our inspection several years ago.

Inspections disappeared in MN a number of years ago as well, I am not aware of any such process dictated from the federal level.

Doesn't disconnecting the battery and then hooking it back up also reset the codes/light ??

Autozone will both read codes and turn off the light for free! If the problem hasn't been fixed - the light will come back on shortly.

nice political discussion, but Diana, why exactly did you folks decide that EGR was causing CEL?

Not a Washington issue, but probably only because the Feds haven't figured out how to make money out of it. We have no emission testing.

I think that the battery disconnect is not the recommended way. Using the scanner is, and as was said AZ will do it for free anyway, but also being patient if you are confident you have corrected the problem, and just driving a few start/warmup cycles will work unless you are in a hurry to pass your emission test. Disconnecting the battery often means not only losing minor things like radio presets and clock time, but this procedure also requires draining the power out of the power control module electrical storage capacitor to reset the fault code. Doing this also drains the memory from the computer and it can take a few days after for the engine management system (PCM)to re-teach itself. What that means is that by losing the CEL light through a battery disconnect you can end up with a possible rough idle for a few days.

By the way, don't bother trying to fool the inspection station by disconnecting the battery or using any other method to erase the trouble code and turn off the "check engine" light. Your vehicle's computer will let the inspection station know that its codes have been erased, and you'll just have to go back again.
