P0236 Turbocharger Boost Sensor A Circuit Range/Performance

  • P0171 System too Lean (Bank 1)
  • P0237 Turbocharger Boost Sensor A Circuit Low
  • P0101 Mass or Volume Air Flow Circuit Range/Performance Problem
  • i would start, given these codes, to look around the air duct assembly for signs of cracks or disconnected hoses resulting in a vacuum leak.

    Where do I start with the array of fault codes on my 2010 opel astra 1.4t?I have cleaned the sensors and checked wiring. Are there separate issues here or could it just be the one sensor?

    P0520 is low oil pressure and all the rest are codes generated by air pressure irregularities within the turbo and air intake pressure.

    2004 x-type 3.0 v6 152,000 miles showed codes P0171, P0174, P2096, P2098, P0101, P0171 pd, P1000.

    check for vacuum leaks or a faulty mass air flow sensor. all the codes have to do with engine too lean(too much air).

    I have a 2005 volvo s60 - i got a P0101 OBDII error code Mass air flow issue - I was going to drive from indy to ann arbor tomorrow - is it ok to do that with this issue? It's a 4 hr drive.

    have the code cleared and see if it comes back, The MAF can go bad, but normally they don't unless your in lots of dust or the air filter is really bad,, check the filter, and reset the code, and enjoy your drive,, you can deal with it when you get home

    What does the P done code mean in a Chrysler Pacifica?

    'P' stands for powertrain-codes will be concerned with engine or trans and are generic, that is they are the same no matter the make of vehicle-OBDII protocol. I.E., a P0171 means a lean reading on bank 1, on a ford, chevy, volvo, toyota-universal general code for all makes and models.
