The P0105 trouble code indicates an issue with the manifold absolute pressure (MAP) or barometric pressure sensor circuit. This code typically points to problems with the sensor responsible for measuring the pressure within the intake manifold or the atmospheric pressure, affecting the engine’s performance.
Manifold Absolute Pressure/Barometric Pressure Circuit
Code symptoms P0105.
1. Decreased engine performance.
2. Rough idling or stalling.
3. Reduced fuel efficiency.
This code is common in brands such as:: Chevrolet, Renault, Ford, Toyota, Nissan, Mercedes Benz, Honda.
Causes of the code P0105.
1. Faulty manifold absolute pressure (MAP) or barometric pressure sensor.
2. Wiring or connector issues within the sensor circuit.
3. Problems with the Engine Control Module (ECM).
Code Solutions P0105.
1. Inspect and replace the manifold absolute pressure (MAP) or barometric pressure sensor if it is faulty.
2. Check and repair any wiring or connector issues in the sensor circuit.
3. If ECM issues are suspected, consult a qualified technician for diagnosis and potential reprogramming or replacement.
