EGR temp sensor cleaned

So I cleaned what I believe to be the EGR temp sensor. Here are some pics. I hope my occasional code 56 disappears now.

Quite the difference, hope it works. I think I'll try it on my Outback, if it has one I can find. I have an occassional EGR code and I've swapped all the components for known working ones from my parts car.

Holy crap! With all that stuff on there, there's no way it was working right. I have a code 55 and 56 popping up myself, I'll have to take a look at mine tomorrow. Hopefully cleaning that fixes it.

So here's another question. When I pulled the sensor out to clean it I looked down inside where the sensor mounts and it looked as bad as the sensor did. Could I spray some carb cleaner down inside there or would all of the gunk get sucked right into the EGR valve and cause problems with it once I started the engine?

That's the EGR temp sensor allright, mine was every bit as bad. It's not hard to access and clean, hope that get's the code for ya.

I wouldn't spray in there without everything EGR and control valve & hoses being off to drain. Even then, you might just make a lump of gunk in there that breaks loose at a bad time.

I'm thinking regular use of injector cleaner in the gas and name-brand gas with "techroline" or the equivalent is a better way to reduce engine deposits. I've become a believer recently after taking my intake off for new vacuum hoses. I cleaned the throttle body good, but the intake was not the best, including the other side of the manifold leading down to the valves. It may not reach all the way thru the EGR system, but its a start...

What did you use to clean it? Does it just wipe it off or do you need a solvent?
