The barometric tension sensor on a 2012 Chevy Cruze can be found on the admission complex and it can gauge the surrounding pneumatic forces where the vehicle is at. This can be valuable in assisting the motor with running great at various elevations. At the point when You drive at higher heights the air is more slender and that can prompt Your motor running ineffectively. With a barometric tension sensor it can peruse the external pneumatic stress and that will permit Your motor to make up for the distinction in pneumatic stress. This can allow the vehicle to have more air in the motor so the pressure proportions stay right to keep the motor running at max execution.
