2001 nissan sentra 1.8L 4cyl. running codes P0105:P1605:P0171:P0325... engine idles fine when in park just not in gear, in gear it shakes pretty bad, also hesitates to accelerate when you press on gas...


code po105 refers to manifold absolute pressure(MAP)sensor/barometric pressure (BHARO) sensor -circuit malfunction==causes--wiring MAP sensor--BARO sensor--ECM
code p0171 refers to system to lean bank 1===causes intake/exhaust leak---AIR system MAF/MAP sensor fuel pressure /pump /injectors--HO2SW
code p0325 refers to knock sensor(KS) 1 bank 1-circuit malfunction====causes--wiring ---poor connections---KS
Check the exhaust flexible pipe at the manifold for cracks
have a fuel pressure test done on the fuel manifold to determine either pump/ filter or pressure regulator.
replace HO2S unit

    What is a P0105 check engine code for a 2003 gmc ENVOY


    OBD2 engine code PO105 is Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction

    Nov 20, 2010 | 2003 GMC Envoy

    2 Answers

    I have a gmc envoy & the trouble codes are p0107,p0130,p0135 & p0171 can you tell me what the problem can be.


    P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

    P0130 02 Sensor Circuit Malfunction (Bank I Sensor 1)

    P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)

    P0171 System too Lean (Bank 1)

    Check your Manifold Absolute Pressure Sensor, and it might be a good time to install a new Upstream O2 Sensor.

    It might also be beneficial to have your fuel pressure checked if the engine is really running Lean, but this may be caused by a faulty O2 sensor.

    Loss of power, stalling at stops and slows, codes P0300, P0107, P0105 and P0105. Will stall but when put into nuetral will start right up.


    The symptoms and the codes you've given would indicate to me that you have a vacuum leak. Look for a loose a throttle body, loose, missing or damaged hoses, loose or missing intake manifold bolts or any other opening in the intake manifold.
    P0105 - Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
    P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
    P0300 - Random/Multiple Cylinder Misfire Detected
