K&N Air filter screwed my MAF according to Dealer...HELP
Hey Guys,

The dealer just informed me that the P0171 code is from my MAF as it sucked in oil from mine AEM Intake and screwed my MAF. he says cleaning it wont help as the damage is internal(dint know how that could happen). He also said that if i replaced it with a new one, he couldnt guarantee if the filter would not screw it up again. Man i just feel like shit right now. I really dont want to go thru the botheration of putting the stock airbox back on. I mean i know a whole lot you guys have CAI's, wat do you guys suggest ?

Thanks

K&N Air Filter or Oil Filter?

You said Oil Filter, but, that isn't anywhere even nearly associated with the MAF.

If you mean the MAF and K&N Air Filter with oil on it, you might try cleaning it, would save some money.

Clean the MAF using electrical cleaner, i think some can be picked up at radio shack.

"In order to remove oily residues from the MAF, you want a non-polar solvent. A "no residue" electronics cleaner/degreaser will work MUCH better than alcohol, as it will have been compounded to dissolve oils and will therefore contain a non-polar organic solvent. Alcohol just doesn't dissolve oil very well - try cleaning your hands with isopropyl the next time you do a bit of wrenching - it's doesn't work very well. Polar solvents dissolve substances that are water soluble, but do not dissolve oily substances. Non-Polar solvents dissolve oily substances, but do not dissolve water soluble substances. Moderately polar solvents have a tendency to dissolve both types of substances. Petroleum distillates are non-polar, alcohols are moderately polar, and water is polar."

Same thing happen to me, no panic. Use Dielectric cleaner, available at radio shack, it is used to clean electronic equipment without leaving a residue.

They also told me that I would have to buy a new MAF sensor
Next time, don;t put as mush oil on the filter.

And tell your dealer they are F&^%king idiots, the TRD filter is the same as the K&N.

Good luck, mine works fine since.

The paper element of popular after market Intakes needs to be oiled in order to help trap dirt/dust particles. Unfortunately, trace amounts of this oil can get sucked up into the Intake and cling to the MAFS.

The MAFS is then unable to get a correct reading of the actual air flow entering the engine. Due to the fact that this oil is coating a portion of the surface area where the sensor takes it's readings, the sensor will detects a lower than actual amount of present oxygen. Because the ECU isn't getting a full reading of the amount of air that has entered the engine, it applies an insufficient amount of fuel. This, of course, creates a lean burning condition that triggers a CEL.

Well, if they claim your MAF is broken, I have one I'm selling. https://www.celicahobby.com/ubbthreads/thread.f_172806_0_collapsed_5__1.html

What are they trying to charge you at the dealership (jerks)?
