Ive got the followijg issue. In cold my boost pressure read 0bar which is correct. But when hot jumps to 0.6bar evem when car is stopped. Funny thing is that car runs great in both conditions. God knows
Never ever use Brake Cleaner or Carburettor cleaner to clean your MAP or MAF sensor. Always use a dedicated MAF cleaner or completely evaporative contact cleaner. Every other fluid in aerosol will kill your MAP or MAF sensor.
@@roger8772brake cleaner is mostly harmless to electrics and plastic unless it is long exposure or soaked in it. Quick blasts are perfectly fine. No need to be dramatic
@@plopping-wetlyacademyofmot9639 Yes buddy, MAPs are still used, but it's mostly MAFs nowadays, can we agree on that? MAPs use predetermined fuel tables where MAFs can adjust fuel based on the incoming air. Plus MAFs are easier to tune vs messing with fuel tables when modifying cars with MAPs.
Very Good detailed video. 👍👍👍
So what if the map voltage is constantly changing. From 0.9 to 3 volts? Would that be normal or faulty?
It’s ok,because the pressure goes up and down…
was that a phone based obd2 scanner and if yes which app are you using?
You can use any OBD2 Bluetooth adapter and Torque app for the phone. The app is free and does more the enough for basic diagnosis.
@@MechanicBasebut which app do you reccomend?
he said Torque App

Break cleaner? I will never leave my vehicle with this guy. Holy shit!
What seems to be the problem?
@@MechanicBase You should probably be using electric parts cleaner and not brake cleaner. Also brake cleaner is not good for plastic components.

@@MechanicBasenever use brake clean on sensors lol they have special cleaner for mass air flow sensor and similiar sensors… USE THAT
@@mightywade27same sh*t different package
Older cars usually use MAP. Newer use MAF. MAP is manifold absolute pressure, MAF is mass air flow.
I've got a 34 year old Volvo 240 with a MAF and a 2009 Sonata in my shop has a MAP. It's not old vs new, it's just the manufacturer preference
@@plopping-wetlyacademyofmot9639 actually MAP sensors came first and MAF sensors came later. Mostly due to EFI systems coming about.

@@XJon2011 right on. I've always found maps more troublesome myself too
