Manifold Absolute Pressure Sensor by Hitachi®. This sensor is designed to properly monitor engine vacuum/manifold pressure to help determine the correct ignition timing and fuel delivery control. Thanks to its high accuracy, the computer can properly adjust air flow and fuel flow for optimal performance, better fuel economy and reduced emissions.
- Accurate vacuum/manifold pressure measurement
- Meets or exceeds original equipment performance specifications
- Quality components provide enhanced durability
- Backed by a 1 year warranty
A Manifold Absolute Pressure (MAP) sensor measures vacuum or pressure in the intake manifold. On a normally aspirated engine vacuum is high at idle and almost zero at wide open throttle. On engines with speed density electronic fuel injection systems that do not use a Mass Air Flow sensor, the MAP sensor signal, along with information from the air and coolant temperature sensors, throttle position sensor, and engine RPM, are used to calculate the intake airflow. Though this part is constructed to be durable, it can fail due to moisture contamination or physical wear. A malfunctioning MAP sensor can't report correct data to the ECU (engine control unit) and can make the engine run rich or lean, resulting in excessive fuel consumption, increased emissions, rough idle, detonation, etc.
If you need a reliable MAP sensor that will optimize your engine's operation, Hitachi will provide you with a quality replacement part. The experts at Hitachi use advanced electronic-sensing and control technology and integrate hardware and software to provide improved fuel efficiency and reduce harmful exhaust emissions without sacrificing power, cost-effectiveness, or the driving performance of the vehicle. This manifold absolute pressure sensor will accurately report vacuum/pressure for better fuel economy, reduced emissions, and smooth operation of your vehicle.
Since its founding in 1910, Hitachi has expanded well beyond the creation of the five-horsepower electric induction motor that was its first product. Today, it is a recognized leader in diverse market segments. Universally known as an Original Equipment Manufacturer that serves major carmakers, Hitachi is increasing its presence in the automotive aftermarket. Headquartered in Tokyo, Japan, Hitachi is famous worldwide for its reliability, innovation, and contribution to moving society forward. The company has pioneered a number of groundbreaking car parts, including the world's first engine central control units, photoelectric crank angle sensors, turbo chargers for rotary engines, etc. With operations in Japan, North, Central and South America, Europe, and Asia, Hitachi develops and manufactures advanced vehicle parts that preserve the environment, enhance safety, and provide comfort.
