Function and Importance

The Nissan Navara 2020 turbo pressure sensor, also known as a Manifold Absolute Pressure (MAP) sensor, plays a crucial role in the engine’s intake system. Its primary function is to measure the absolute pressure of the intake air in the intake manifold, after the throttle body. This data is transmitted as a corresponding voltage signal to the Engine Control Module (ECM).

The ECM uses this information to:

• Determine Intake Airflow: Accurate airflow measurement is essential for precise fuel-air mixture control, optimizing engine efficiency.
• Adjust Ignition Timing: Optimal ignition timing depends on various factors, including intake airflow, engine speed, and load. The MAP sensor’s input helps the ECM fine-tune this timing.
• Control Emissions: By precisely regulating the fuel supply based on actual intake airflow, harmful emissions are minimized.

Sensor Construction and Components

The sensor consists of a vacuum chamber separated by a thin silicon diaphragm, maintaining a standard level. A silicon chip (IC) is integrated within this chamber. One side of the chip is exposed to intake manifold pressure, connected via a tube and filter. The other side is exposed to the vacuum of the sealed chamber. A connector is also a key component. The silicon chip, acting as the sensor’s core, measures pressure and withstands deformation thanks to an integrated Wheatstone bridge (a circuit used for precise resistance measurement). Modern sensors are directly manufactured by sensor producers and offer high integration.

Key components typically include:

• Diaphragm: A pressure-sensitive membrane that deforms under the influence of intake air pressure.
• Resistive Transducer: Converts the diaphragm’s deformation into a corresponding voltage signal.
• Electronic Circuitry: Amplifies and processes the voltage signal from the transducer.
• Housing: Protects the internal components from environmental influences.

Sensor Location and Operation

The MAP sensor is usually located above the intake manifold, near or on the throttle body, or before the turbocharger. It acts as a barometer. Before starting the engine, with no vacuum present, it signals the ECM to establish baseline air density. When the engine runs, pressure increases and air density decreases. This difference affects the chip, altering the resistance and thereby the voltage. The Engine Control Unit (ECU) then integrates signals from the MAP sensor, Intake Air Temperature (IAT) sensor, Engine Coolant Temperature (ECT) sensor, and RPM sensor to calculate air density, precisely determining the air mass and optimizing the fuel-air ratio before combustion.
