Repair Difficulty Level: 2/3   
Comments  |  Add Comment

Possible causes

  • Faulty Manifold Absolute Pressure sensor
  • Manifold Absolute Pressure harness is open or shorted
  • Manifold Absolute Pressure sensor circuit poor electrical connection
  • Faulty Powertrain Control Module (PCM)
  • Tech notes

    According to some users, the code could be triggered by disconnecting or recharging the car battery. Before replacing any parts, clear the code and drive your vehicle for more than 50 miles and/or a few days.

    When is the code detected?

    An excessively low or high voltage from the sensor is sent to Powertrain Control Module (PCM)

    Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Engine rough idle
  • Engine hesitation
  • P0106 Hyundai Description

    The amount of intake air flow must be inputted to Powertrain Control Module (PCM) in order to determine the fuel injection quantity. MAPS(Manifold Absolute Pressure) calculates the amount of air indirectly as measuring the pressure inside of intake manifold. This mechanism is also called Speed-Density Type. MAPS transfers analog output signal which is proportional to the change of intake manifold pressure, then, with this signal and RPM, PCM calculates the amount of intake air flow. MAPS is mounted on surge tank to measure the pressure inside of intake manifold, and it consists of a piezo electric element and hybrid IC which amplifies output signal from the element. A piezo electric element is a sort of a diaphragm using piezo electric effect. One side of the diaphragm is surrounded with vacuum chamber while intake pressure is applied to the other side. Thus, signals are outputted by the transformation of diagphragm according to the change of pressure inside of intake manifold.
