What should the fuel pressue be? And will a fuel pressure reading of 43 psi to 49 psi cause a MAF sensor code
Do you

Hello,

If that is your fuel pressure it is fine. If you are getting a MAF code first thing to do is to get some MAF Cleaner and clean it. About 7 out of 10 times it just needs to be cleaned.

Check out the following link for more info on how the MAF works....
