P0105

DTC P0105, sometimes indicated as P010500 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing manifold absolute pressure/barometric pressure circuit malfunction.

The manifold absolute pressure (MAP) sensor measures the absolute pressure of the air in the intake manifold. The barometric pressure sensor measures the atmospheric pressure. The MAP sensor and barometric pressure sensor are both used by the engine control module (ECM) to calculate the air mass entering the engine.
The P0105 code is set when the ECM detects a malfunction in the MAP or barometric pressure circuit. The most common causes of this code are a failed MAP or barometric pressure sensor, a failed ECM, or a wiring problem.
If the code persists after replacing the sensor, the ECM may need to be replaced. If there is a wiring problem, the wiring should be checked for shorts and opens.

• P0105: Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
• P0105: Manifold Absolute Pressure/Barometric Pressure Circuit
• P0105: MAP/BARO Circuit Malfunction
• P0105: Manifold absolute pressure (MAP) sensor/barometric pressure (BARO) sensor – circuit malfunction
• P0105 00: Incorrect signal from the MAP pressure sensor
• P0105 00: Manifold absolute pressure (MAP) sensor/barometric pressure (BARO) sensor - circuit malfunction

These codes are commonly diagnosed with error code P0105.
