Black Rover with about 207,000 miles runs great actually perfect but failed the emissions test and trying to figure out how to test the maf. Does anyone know how to test the MAF? The camshaft sensor is relatively new I'm pretty sure it's fine.

 

Put the codes into
http://enginecodemaster.com

Like P0174 or such.


Do not touch the MAF..

You can spray CRC sensor cleaner into the MAF when the truck is turned off.

But that is all I would do.

 

jfall... I have electronic parts cleaner is that not the same as CRC sensor cleaner? Thanks for your help and the code master site.

 

cleaning the MAF did not work for me, and that was with using MAF sensor cleaner. bought a new Bosch from partsgeek (no affiliation) for $100. truck runs like a champ, no codes (well, except the amigos that I haven't gotten to yet).

 

get the crc cleaner.

not sure if same,

goal is low risk to MAF
