- Faulty Engine Control Module (ECM)
How do I fix code P1105 INFINITI?Check 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.
Cost of diagnosing the P1105 INFINITI code
Labor: 1.0The cost of diagnosing the P1105 INFINITI code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?An excessively low or high voltage from the sensor is sent to Engine Control Module (ECM).
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine rough idle
- Engine hesitation
P1105 INFINITI DescriptionThe 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 Infiniti vehicles the absolute pressure sensor is built into ECM.
