The P1105 code is a manufacturer specific powertrain code that means the engine control module (ECM) has detected a fault or malfunction with the Manifold Absolute Pressure (MAP)/Barometric (BARO) pressure switch solenoid valve.
Codes related to the P1105 include:
A code P1105 will be stored when the voltage signal from the MAP/BARO pressure switch that received by the engine control module (ECM) is too high or too low.
The ECM uses the Manifold Absolute Pressure (MAP) sensor to read manifold pressure and calculate air density and air mass flow rate. This information then determines how much fuel metering is needed for combustion. The MAP/BARO switch solenoid valve is used to switch the airflow passage based on voltage signals sent by the ECM.
Some Nissan vehicles will have the MAP sensor is built into the ECM.
Several problems may cause a P1105 code including:
Symptoms of a P1105 code may include:
