P1105 INFINITI Meaning

The Manifold Absolute Pressure (MAP) sensor provides instant manifold pressure information to the engine’s Engine Control Module (ECM). The data is used to calculate air density and determine the engine’s mass air flow rate, which in turn determines the required fuel delivery for optimum combustion. A fuel-injected engine may also use a Mass Air Flow (MAF) sensor to detect intake air flow. A typical configuration employs one or the other, but rarely both. The MAP/BARO Switch Solenoid Valve switches the air flow passage based on the voltage signal sent by the ECM.
In some Infiniti vehicles, the Manifold Absolute Pressure sensor is integrated into the ECM.

Faulty Engine Control Module (ECM)

How to Fix Code P1106?

Start by checking the “Possible Causes” listed above. Visually inspect the corresponding wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

What Does It Mean?

Sometimes P1106 is set when the Engine Control Module (ECM) cannot read the BARO sensor circuit. Before replacing parts, try performing the ECM reset procedure.

– Clear the code
– Start the engine
– Maintain engine at 3000 RPM with no load (in park or neutral) until the radiator fan turns on, then let it idle
– Road test with A/T in 2nd position, M/T in 4th gear
– Press accelerator pedal halfway down for five seconds
– Check codes again
– If codes return, the ECM may need replacement. If codes don’t return, the problem is fixed.

The Barometric Pressure (BARO) sensor is built into the Engine Control Module (ECM) and monitors atmospheric pressure. The ECM estimates appropriate intake air flow from the Manifold Absolute Pressure (MAP) sensor output voltage and the BARO sensor output voltage. If the BARO sensor output voltage is at or above a specified value, the ECM detects a malfunction and a code is stored.

P1106 BUICK Meaning

The Manifold Absolute Pressure (MAP) sensor responds to changes in intake manifold pressure. Pressure changes occur based on engine load. The MAP sensor has the following circuits:
– 5 Volt Reference Circuit
– Low Reference Circuit
– MAP Sensor Signal Circuit

The Powertrain Control Module (PCM) supplies 5 volts to the MAP sensor on the 5 Volt Reference circuit. The PCM also provides a ground on the Low Reference circuit. The MAP sensor provides a signal to the PCM on the MAP Sensor Signal circuit that corresponds to pressure changes in the manifold. The PCM should detect a low signal voltage at low MAP, such as during idle or deceleration. The PCM should detect a high signal voltage at high MAP, such as when the ignition is ON with the engine off, or at wide open throttle (WOT). The MAP sensor is also used to determine barometric pressure (BARO). This occurs when the ignition switch is turned ON with the engine stopped. The BARO reading may also be updated whenever the engine operates at WOT. The PCM monitors the MAP sensor signal for voltage outside the normal range.
