It's well known that the air changes its properties depending on the temperature and altitude. High in the mountains, the air gets thinner, while colder air is denser, and these factors influence not only the way you feel but also engine operation. It's crucial in conventional road-going and off-road vehicles and especially in snowmobiles, which are often used in such conditions during the cold season. To provide good engine performance throughout the powerband, airflow has to be measured very precisely. Even relatively outdated carbureted motors installed in older Ski-Doo models in the mid-1990s had a high altitude compensator (HAC) system featuring a diaphragm that flexed in response to air pressure change.

By the early 2000th, such mechanical systems were mainly superseded by electronic ones. In order to determine how much fuel has to be supplied at any given moment, the control module relies on data coming from various sensors such as a throttle position sensor and a so-called T-MAP sensor measuring air temperature and pressure at once. Direct injection used in many modern two-stroke motors such as Rotax 600 H.O. E-TEC requires especially precise monitoring of incoming air. When it comes to all-terrain vehicles and personal watercraft, the situation is mainly the same – besides the current throttle position, the ECU has to know the air temperature and pressure for the motor to run adequately.

Stuffed with electronics, all these sensors provide effective engine operation in all working modes but gradually wear out or just break. Minor parts found inside these devices are subject to vibration and temperature extremes, and as the whole sensor's construction is virtually irreparable, replacing the faulty sensor(s) is the finest decision. On our virtual pages, you will find plenty of powersports air intake sensors for an ATV/UTV, snowmobile, PWC, etc. Manufactured by reputable aftermarket companies, these products are known for high quality yet have a reasonable price.
