Instrument gauge code -111, -112, -113
Later I downloaded OBOII codes and only received P0715 which has nothing to do with MAF.
I don't have a problem replacing the MAF if it is truly bad. How do I verify?
And is the P0715 potentially associated with a transmission sensor issue?
Lastly I need a recommended link to download 1999 SL500 service manual.
Thanks
