P0105 Code - Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction

Quick Answer

The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Common causes include Faulty Manifold Absolute Pressure (MAP) Sensor, Manifold Absolute Pressure Sensor harness is open or shorted, Manifold Absolute Pressure Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0105 Description

The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. Pressure in the intake manifold is affected by engine speed, throttle opening, air temperature, Barometric Pressure (BARO) and if equipped, turbocharger output. A diaphragm within the MAP sensor is displaced by the pressure changes that occur from the varying load and operating conditions of the engine. The sensor translates this action into electrical resistance.
The MAP sensor wiring includes 3 circuits. The Engine Control Module (ECM) supplies a regulated 5 volts to the sensor on a 5 V reference circuit. The ECM supplies ground on a low reference circuit. The MAP sensor provides a signal voltage to the ECM, relative to the pressure changes, on the MAP sensor signal circuit. The ECM converts the signal voltage input to a pressure value.
Under normal operation the greatest pressure that can exist in the intake manifold is at ignition ON, engine OFF, which is equal to the BARO. The lowest manifold pressure occurs when the vehicle is idling or decelerating. The ECM monitors the MAP sensor signal for pressure outside of the normal range.
The Diagnostic Trouble Code (DTC) will be set when the ECM receives an excessively low or high voltage from the MAP Sensor.

  • Why Chrysler(or Dodge) does NOT appear above? Curious, because on my Dodge Straturs R/T (Mexico only) Turbocharged 2.4L Sedan, I can EASILY Access codes on the odometer display, and see them on a web available list, printed and put into the vehicle without any need for a Scanner, YOu only need to execute the "Key-Dance" (Turn ignition key in the following sequence: OFF>ON>OFF>ON>OFF>ON within 5 seconds and all codes will appear on the odometer.
    My other Dodge, a 1991 Spirit R/T Turbo,has the same capability built in: but it flashes de CHECH ENGINE light in a kind of Morse code: light-on, pause, two light flashes.... means code 12!
    That in one good reason to have a Chrysler or Dodge: Look Ma, NO scanner! Amclaussen, Mexico City.
