Manifold air temperature sensor.

The data is used to calculate air density and determine the. New 4928594 4921746 4087989 pressure sensor replacement for cummins exhaust gas. A map sensor that measures high intake manifold pressure indicates high engine load to the pcm. Engines that use a map sensor are typically fuel injected the manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine s electronic control unit ecu.

The manifold absolute pressure sensor map sensor is one of the sensors used in an internal combustion engine s electronic control system. An iat sensor is an important component that is needed while starting up a vehicle s engine. Only 11 left in stock order soon. The sensor circuit can be checked for proper voltage using a voltmeter.

A faulty sensor can decrease the life of the engine and reduce the efficiency of fuel consumption. The pcm in response increases the amount of fuel to the engine so that the proper air fuel mixture is maintained. This information is very useful for the engine control unit or ecu for many functions and calculations such as calculating the air density for effective ignition timing and fuel efficiency. This results in an increase of fuel being injected into the engine.

A failed map sensor has serious implications on fuel control vehicle tailpipe emissions and fuel economy. All air charge and manifold temperature sensors are 100 factory tested to ensure trouble free performance featuring the broadest sensor coverage in the market we meet the service professionals needs with the highest quality product every time he opens the box. Intake manifold pressure temperature sensor 2897333 for cummins isb6 7 b6 7 qsb6 7 3 6 out of 5 stars 3. The intake air temperature sensor or iat sensor has the core function of monitoring the temperature of the air that is entering the engine of your vehicle.

Symptoms of a bad or failing map sensor include. The pcm unknowingly is creating a rich condition which can cause your engine to run rough. A manifold temperature sensor that sends out a low temperature reading tells the pcm that the incoming air is very dense. The air charge manifold sensor temperature reading should closely match the engine cool ant temperature reading on a scan tool if the engine has not been run for over an hour.
