P1103 2002 Nissan Sentra Code - MAP Sensor High Voltage

Quick Answer

The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). Common causes include Faulty Manifold Absolute Pressure (MAP), Manifold Absolute Pressure (MAP) harness is open or shorted, Manifold Absolute Pressure (MAP) 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 P1103 2002 Nissan Sentra Description

The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine's Engine Control Module (ECM). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.The MAP/BARO Switch solenoid valve switches it's air flow passage according to the voltage signal sent from the ECM.
