P1104 NISSAN - MAP Sensor Low Voltage
P1104 NISSAN Possible Causes
- Faulty Manifold Absolute Pressure (MAP)
- Manifold Absolute Pressure (MAP) harness is open or shorted
- Manifold Absolute Pressure (MAP) circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How is the P1104 NISSAN code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
What is the cost to diagnose the P1104 NISSAN code
Labor: 1.0The cost to diagnose the P1104 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

P1104 NISSAN MeaningThe 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.
In some Nissan vehicles the absolute pressure sensor is built into ECM.
