|What are the Possible Causes of the P1105 INFINITI Code?

  • Faulty Manifold Absolute Pressure Switch Solenoid Valve
  • Manifold Absolute Pressure Switch Solenoid Valve harness is open or shorted
  • Manifold Absolute Pressure Switch Solenoid Valve sensor poor electrical circuit connector
  • Faulty Engine Control Module (ECM)

|How to Fix the P1105 INFINITI Code?

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 P1105 INFINITI code?

Labor: 1.0

The cost to diagnose the P1105 INFINITI code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P1105 INFINITI code detected?

An excessively low or high voltage from the sensor is sent to Engine Control Module (ECM).

|What are P1105 INFINITI code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Engine rough idle
  • Engine hesitation

|What Does the P1105 INFINITI Code Mean?

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.
In some Infiniti vehicles the absolute pressure sensor is built into ECM.
