This is where it is.
You probably have to remove the air box to make room.
Disconnect the harness
Unbolt the ESS (usually from below)
Clean it with Brake cleaner
Attach the connector.
Bolt it back in... this is tricky

Cleaned mine today and man...that thing was filthy!



I didn't realize it was an exposed sensor. Figured it was up inside somewhere. No wonder it gets so dirty! Cleaned it up with MAF cleaner, looks good as new.

yea, and after looking at it it almost looked like you could clean it without removing it..but I didn't try it so I'm not sure.

Does it matter if I touch the sensor? Or, do just spray the bajeebus out of it and let air dry?

It is a magnetic inductive pickup and all you need to do is wipe the dirt off of it with a rag, as has been stated. Dirt is not as much of a problem as is the possibility of ferric metals attaching themselves to the sensor and causing erratic readings from the trigger wheel behind the pulleys. These erratic signals will cause ignition and fuel injector timing issues, which results in poor driveability.

After an engine replacement, (3) sets of coils including the BHR Ignition Kit, and going through 2 MAF sensors.....this was my issue.

It caused a lot of vibrations at idle which were very different from the normal "engine mount" issue.

Thanks Charles!

Charles do you recommend that this be done yearly or at a certain mile interval? I'm at 86,000 miles and I'm certain that mine has never been removed. Do you think it is possible to pull it out from the bottom of the car. I've always disconnected mine by reaching up from under the car. I think I could get a ratchet up there to loosen it. Stay tuned.

I wipe my sensor off whenever I perform any kind of maintenence under the hood. It is simple, easy, quick, and prevents a lot of weird stuff happening. I don't even remove it from the engine to do so.

any tips on getting to the ESS. I have only pulled the plug on the ESS when i am pulling seafoam into my engine. Its a PIA to get to from above...unless I am making this harder than it should be.

If you need to remove then do it from below.... it's a bit tight in there (that's what she said...)
Reinstalling the bolt is easier with the wiring connector attached

If you remove the air box you can see it and maybe clean it from above...
