fAO splitpin (or anyone about MAFs)
 

Been having a problem with the my97 cutting out over the last month or so (search my user name to see) anyway tonight it finely gave me some error codes ,CEL light came on.
Code 12 Starter switch , Code 23 Mass air flow sensor and Code 45 Pressure sensor / Pressure exchange solenoid valve , My Question is now how do i change them ,
Code 23 is the maf unit which is a straight swop over when i can get it but what about the other codes where are they ,

also is it safe to drive the car until i can get the new maf unit .Thanks in advance

If the MAF is faulty, I'd NOT drive it, or at least, keep it RIGHT off boost. If you don't have a boost gage, don't risk it.

Can I ask what sort of induction and what dumpvalve you are running?

Bailey dump valve ,but know the induction kit was on when i got it , its a cone on the end of the MAF.:wonder:

DF, wil reply to the other post you've started as R1C's already posted some good info there.
