Types of MAP Sensor for Mitsubishi Mirage 1.5L

Engine control unit uses pressure data from the intake manifold provided by the MAP sensor for Mitsubishi Mirage 1.5L. There are different types of MAP sensors, and they include the following:

• Barometric Pressure Sensors

  These sensors are used primarily in vehicles operating at high altitudes. The MAP sensor calculates the barometric pressure when the vehicle is off. This value is used as a reference during the vehicle's operation.

• Absolute Pressure Sensors

  This is the most common type of MAP sensor found in many Mitsubishi Mirage vehicles. The absolute pressure sensor constantly measures the pressure in the intake manifold relative to a complete vacuum. The readings from this sensor inform the engine control unit about the current engine load status.

• Difference Pressure Sensors

  Difference pressure sensors measure the pressure difference between the intake manifold and the atmosphere. This data helps the engine control unit understand how much the driver is pressing the accelerator. It aids in precise control of the engine's torque output.

• Voltage Output MAP Sensors

  These sensors send a continuous voltage signal to the engine control unit, reflecting the pressure changes in the intake manifold. The control unit interprets this voltage signal to adjust fuel injection and ignition timing, optimizing engine performance and emissions.

• Current Output MAP Sensors

  Current output sensors provide a more precise and responsive signal to the engine control unit. They are used in modern high-performance engines. The sensor's change in current reflects the pressure variation in the intake manifold. The engine control unit uses this information to make real-time adjustments to the engine's operating parameters.

Specification and Maintenance of MAP Sensor for Mitsubishi Mirage 1.5L

The MAP sensor on the Mitsubishi engines measures the pressure of the intake manifold. This pressure changes according to the engine speed and load. The sensor converts the measured pressure into an electrical signal and sends it to the Engine Control Unit (ECU). The ECU uses this information to adjust the air-fuel mixture and ignition timing, optimizing the engine's performance and efficiency.

The specifications of the MAP sensors are as follows:

• Pressure Range: The MAP sensor measures a range of pressures, usually from 10 to 30 inHg (inches of mercury) or 50 to 300 kPa (kilopascals). This range allows the sensor to monitor changes in engine load and speed accurately.
• Output Signal: MAP sensors generate an analog voltage signal between 0.5 and 4.5 volts, depending on the pressure being measured. This signal is sent to the engine control unit (ECU) for further processing. The voltage change corresponds to changes in engine load and speed.
• Supply Voltage: MAP sensors typically operate at a supply voltage of 5 volts from the ECU. This voltage powers the sensor's internal circuitry and is used for signal processing.
• Temperature Range: MAP sensors must function reliably under extreme temperature conditions. They are often designed to operate within a temperature range of -40 to 125 degrees Celsius (-40 to 257 degrees Fahrenheit).
• Accuracy: MAP sensors must be highly accurate to maintain engine performance and emissions standards. Their accuracy is usually ±1% of full scale, ensuring precise pressure measurements.
• Hysteresis: Hysteresis refers to the difference between a sensor's output signal for increasing and decreasing measured values. For MAP sensors, hysteresis is typically less than 0.5% of full scale, ensuring consistent and reliable performance.

Here are some tips on how to maintain the Mitsubishi Mirage MAP sensor.

• Regular Inspection: Check the condition of the MAP sensor and its electrical connectors for any signs of wear, damage, or corrosion. Also, visually inspect the vacuum hoses and look for cracks, leaks, or loose connections.
• Clean the Sensor: Over time, carbon deposits and contaminants can accumulate on the MAP sensor and affect its performance. Use a suitable cleaner to remove these deposits and restore the sensor's accuracy.
• Replace Vacuum Hoses: The vacuum hoses are crucial for the proper functioning of the MAP sensor. These hoses transport the pressure variations from the intake manifold to the sensor. If the MAP sensor indicates incorrect pressure readings, check the vacuum hoses for any damage or leaks and replace them as needed.
• Check Electrical Connections: Ensure that the electrical connectors between the MAP sensor and the ECU are secure and free of corrosion or damage. Poor electrical connections can cause faulty sensor signals and affect engine performance.
• Follow Maintenance Schedule: Adhere to the recommended maintenance schedule in the vehicle's owner's manual. Regular servicing, including engine oil changes and air filter replacements, helps maintain engine health and sensor performance.
