Niterra launches NTK brand MAP sensors

The company's expert warns that the use of this low-quality component or not compatible with the vehicle causes increased fuel consumption and pollutant emissions

São Paulo, October 2023 - Niterra, Japanese multinational owner of the NGK and NTK brands and specialist in components for ignition systems and sensors for injection systems, announces the launch of new MAP sensors (Manifold Absolute Pressure) of the brand NTK. It is an absolute pressure sensor of the intake manifold that is fundamental for the correct functioning of the injection system - The most used in Brazilian cars.

"When the injection system applies the strategy called "speed density", It is through your information that it will define the mass of air that is entering the engine.", explains Hiromori Mori, technical assistance consultant at Niterra do Brasil. "With that data, The injection module will perform the calculation of the mass of air that is entering the engine and, once the air mass has been determined, the mass of fuel to be injected is calculated."

Mori warns that the use of low-quality MAP sensors or not compatible with the vehicle directly interferes with this calculation, causing increased fuel consumption and pollutant emissions.

"There is a common practice in Brazil of trying to clean the sensor. If the component is new, No problem. Now, if you have been suffering from contamination and heating for many years, The most recommended is to make your exchange. It's a low-cost part and doesn't justify keeping it in the car if it's not in perfect condition.", points out the Niterra expert.

According to Mori, Replacing the MAP sensor is relatively simple. "A very important precaution is to check for possible false air intakes caused by problem gaskets and seals", alert. "The false air intake significantly alters the reading of the MAP sensor."

It is also necessary to observe, according to Mori, any mechanical and electrical problems in the engine, as an out-of-sync engine, compression, Valve regulation and sensor supply voltage, between others. "These failures can affect the sensor reading", Says.

The highest risk of driving a vehicle with faulty or damaged MAP sensors, informs Mori, is related to engine malfunctions, that, beyond discomfort, may generate unforeseen events in the driving of the vehicle. "In turbo engines, where the sensor indicates the pressure on the supply, errors in component reading can lead to excess pressure that leads to engine damage.", states the expert of Niterra.

To keep MAP sensors in good working order, Mori recommends the driver to keep the maintenance of the vehicle up to date, check the level of engine lubricating oil and always use the specific oil. "The best practice is that, during periodic reviews, the consumer asks his trusted mechanic to check the correct functioning of the injection system", concludes Mori.
