It's really a DAEWOO car.+ Suzuki +GM.(good luck!)
with GM 2.0L L34 engines, common in USA.
wiki it and see the horror yet>?


your map sensor is bad or dirty. (clean it , visual inspection, time....gunk in the vac port?)

or the PCM is confused, what does that mean?,
it means the vacuum is bouncing (bad cam timing or worse) and PCM can't know that and sees vacuum wrong.
find a real ASE shop and avoid the zone.

here is the official page on this code
Trouble Code: P0107 (2.0L L4 VIN - Auto)
Manifold Absolute Pressure (MAP) Circuit Low Input

Trouble Code Conditions:
MAP: 5 kPa, 37.5 mmHg or less (Low pressure-High vacuums-Low voltage)

Possible Causes:

“Lg” circuit open or shorted to ground

“Or/G” circuit shorted to ground

MAP sensor malfunction

ECM malfunction

and engine vacuum IS wrong. (bouncing?)

    the AZ scans can miss many important DTCs (errors). the error is serious,.there is a serious problem. why not post ALL DTC , not just 1.? get real mech, to scan it with a REAL scan tool. (a full scan tool costs $200) Btw? did you check all fuses first.?

    There is a lot of false information on this site.
    First off, autozones scan tool is perfectly capable of reading all dtc's.
    What it CANT read is ABS, bcm codes and some tcm codes.
    Secondly, a "real" scanner does not cost $200. I paid 50$ for mine and can read all DTC's, ABS, body/transmission computer and realtime monitor sensor reference voltage.
    The one thing that's right is the code IS a map sensor. It's located right underneath the throttle body and has a small 6" extension pigtail. Try taking it out and cleaning the end. Sometimes dirt and carbon accumulate and cause the sensor to not be able to read correctly. Make sure to clean the terminals on the sensor as well as both pigtail plugs. Reset the code and try again. If that doesn't solve the problem replace the sensor.

    And just as a follow up, there are no fuses for the map sensor

    the map is powered by the PCM +5vReg internal supplies.

    the OPs error is not listing ALL DTCs
    and some tools DO NOT READ FACTORY codes
    that is a fact,
    and what yours does, who can care?, nor mine.
    what matters is getting all codes and the posting them.
    and is not done yet.

    my guess is he means , lists 4 different things , is the silly book lists 4 possible causes. well that is a book lie.
    the book fails to show engine vacuum bad in the list. amazing fact.

    all ASE mechs know the books are just guide lines, not all inclusive of REALITY.
    nor does it list , that the cam belt slipped
    and is now retarded timing and vacuum is weak and is bouncing.
    or just put (bad engine in the list)
    simple and accurate.
    we do the basics first. not jump all over the map sensor , just because the lame PCM thinks it reads low, gee it might be low...

    btw this PCM has P0,P1, P2 codes. and more.,
    some tools cant do those..abpve P0

    just as a 1 year old follow up, LOL!

  • _-__-___-_
    _-__-___-_ Aug 23, 2015

    the PCM only knows the vacuum is low
    that be it. (if no other codes stored or live)

Code po107

Just because your getting a code from a sensor doesn't mean the sensor is N/G. The MAP sensor reads the manifold air pressure, that can be anything from a vacuum leak, elec short, bad plug/wire, miss, gasket and the list goes on. It can be a bad sensor too, don't get me wrong. Does it run rough, hard start, did you ck the emissions? First things first Vacuum leaks & gaskets are popular. Once in a while I cross paths w/ a cracked manifold. Don't throw your $ out the window, Do it once & do it right. Good luck
