Sonic909 Posted May 16, 2018 Report Share Posted May 16, 2018 Got a MAF sensor error code (no check light though) and a hesitant acceleration. About to fit a new MAF (cba with cleaning it 104k miles) Is there any common failure areas to check for vacuum leaks whilst I’m there.

Patt Posted May 16, 2018 Report Share Posted May 16, 2018 First places to check: Intake pipe - I've seen many with loose clips at the MAF or not correctly secured at the throttle body. Next is the horizontal pipes between the intake manifolds - very easy to not get a seal all the way round. After that it's the silly small pipes that will perish over time, or just get dislodged by a clumsy grease monkey Link to comment Share on other sites More sharing options...
mikefocke Posted May 17, 2018 Report Share Posted May 17, 2018 Was there any work recently done on the top of the engine? Most often the MAF is not really a MAF failure but one of the inputs to the ECU is out of spec and the ECU reports the code as being MAF because some other variable is causing the imbalance. Info on how the MAF works here. Link to comment Share on other sites More sharing options...
