Mass air flow sensor

[Rocket Man]

Hey guys, I have a quick question. My 2006 Denali has thrown a code three times now for a MAF sensor. I have a spectre intake I bought from @Rocket Man , that’s been great. It only started throwing the code after the first time I took the filter off the intake to clean it. It’s sporadic. About a month apart each time, and each time while at some point, climbing or descending grades. I’ve used my code reader to clear and it hasn’t presented issues that I can tell. Is this an indication that I need to clean my MAF or do I need to replace it?!

Yep clean it. Sometimes the oil from the filter gets on the MAF. Be sure to apply the oil like the directions show, no more oil than called for.

And be careful cleaning the MAF. Don't be manhandling that thing. Try not to touch the wires. Just hold it out and spray it and let it evaporate a couple times.

^^^ONLY USE THE MAF SENSOR CLEANER IN A CAN THAT SAYS MAF SENSOR CLEANER ON IT!

Seriously, though, unlike a lot of chemicals we use like carb cleaner (methanol and acetone) or brake cleaner (perc) that are just labeled for marketing, if you look at the SDS for the MAF cleaner, it is a very specific cocktail of solvents. Accept no substitutes.

Yeah that’s what I was thinking. I need to do it before I head to Justin next week at black bear. Wanna make sure that’s all in order! Thanks for the responses guys!
