Genuine Pontiac Torrent MAP Sensor

The Pontiac Torrent MAP Sensor provides precise intake pressure information so that the engine computer can mix fuel properly to provide the compact SUV with smooth power and good mileage. By monitoring absolute air pressure within the intake manifold and sending real-time numbers to the ECU, the MAP Sensor allows the speed density system to calculate air density and determine how long to keep the fuel injectors open. It also determines spark timing and aids in onboard diagnostics testing the EGR valve. Early model years applied a single MAP Sensor in the naturally aspirated V6. However, later turbo-based packages, although rare, paired that same sensor with a mass airflow unit so that the ECU could reconcile boost figures. The difference was that the added component measured volume flow while the original MAP Sensor tracked total pressure and never registered negative vacuum values. Inside Pontiac powertrains, the component can also convert pressure and intake air temperature into air mass in the case of the IAT sensor. Across every Pontiac Torrent edition, this unit is still a small plastic transducer connected by a sealed plug to convert the manifold pressure into a clean voltage signal that is easily read by the ECU in milliseconds, making the whole Torrent responsive at varying altitudes. A healthy MAP Sensor ensures fuel trim and low emissions.
