Turbocharger Boost Manifold Absolute Pressure Sensor MAP Sensor Compatible with 2003-2007 Dodge Ram 2500 3500 L6 5.9l Cummins Diesel Trucks Engine Replaces 3949988 5139278AA

Turbo Boost Pressure Map Sensor the 2003-2007 Dodge Cummins Turbo Diesel trucks with the 5.9-liter engine. Replaces OEM Part Numbers: 3971106, 5139278AA. The electrical control system of an engine uses the Manifold Pressure Sensor. Fuel injection is used in engines that use a pressure sensor. The sensor sends information about manifold pressure to the engine's electronic control unit in real time. The information is used to calculate air density and the engine's air mass flow rate, which determines the amount of fuel required for perfect combustion. A MAF sensor, a Pressure sensor, or both may be used to monitor intake airflow in a fuel-injected engine.FITS THE FOLLOWING VEHICLES:2003, 2004, 2005, 2006, 2007 DODGE RAM 2500 / 3500 L6 5.9LFEATURE AND SPECIFICATIONS:Color: BlackMaterial: PlasticIt is easy to install and remove.Package includes: 1 Map SensorDesigned to lower exhaust emissions.Exquisite workmanship provides long service life.Great replacement for your old one or broken one.It recirculates the portion of the gas coming out of the engine.ABSOLUTE PRESSURE (BOOST MAP SENSOR):MAP sensors measure absolute pressure. Boost sensors or gauges measure the amount of pressure above set absolute pressure. That set absolute pressure is usually 100 kPa. This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system.COMMON NAMES FOR THE MANIFOLD PRESSURE SENSOR (MAP SENSORS) ARE: Manifold Absolute Pressure SensorEngine Load SensorPressure SensorBoost Sensor

• MAP SENSOR - The manifold absolute pressure sensor (MAP sensor) is one of the sensors in an internal combustion engine's electronic control system. In engines with a MAP sensor, fuel injection is widespread. Under varying engine running loads, a manifold absolute pressure sensor (MAP) monitors variations in manifold pressure and delivers a signal to the engine control unit (ECU). The original Boost MAP part numbers are 3971106 and 5139278AA.
• BOOSTING PRESSURE - The Manifold Pressure Sensor is useful for diagnostics since it gauges throttle and turbo performance as well as detecting leaks in the inlet manifold. Unless the turbo charger is boosting pressure, it should always read a negative pressure due to its position.
• THE MANIFOLD ABSOLUTE PRESSURE MAP SENSOR PROVIDES INSTANT MANIFOLD PRESSURE INFORMATION TO THE ENGINE'S ELECTRICAL CONTROL UNIT (ECU). The information is utilised to calculate air density and estimate the engine's air mass flow rate, which determines the required fuel metering for optimal combustion and influences ignition timing advance or retard.
• LIFE IN SERVICE - Made of high-quality materials that are extremely long-lasting, heavy-duty, and corrosion-resistant. Designed to reduce the amount of pollution released into the atmosphere. It recirculates the gas that is ejected from the truck engine. It's simple to set up and take down. Long service life is ensured by fine craftsmanship.
• IMPORTANT NOTE - Please double-check the description or use the year/make/model and OE component numbers, drop-down menu, and interchangeable component numbers to guarantee compatibility before purchasing. THIS IS NOT A SENSOR FOR AN INTAKE MAP. THIS IS NOT THE CORRECT PART TO PURCHASE IF YOU NEED AN INTAKE MAP SENSOR!
