Manifold Air Temperature Sensor

Check out all the relays.

Manifold air temperature sensor. A failed map sensor has serious implications on fuel control vehicle tailpipe emissions and fuel economy. A faulty sensor can decrease the life of the engine and reduce the efficiency of fuel consumption. 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. Motoall pressure temperature sensor for cummins truck m11 isc isl ism isx isb2897334 3 1 out of 5 stars 4.

An iat sensor is an important component that is needed while starting up a vehicle s engine. Symptoms of a bad or failing map sensor include. The pcm in response increases the amount of fuel to the engine so that the proper air fuel mixture is maintained. A manifold temperature sensor that sends out a low temperature reading tells the pcm that the incoming air is very dense.

The pcm unknowingly is creating a rich condition which can cause your engine to run rough. The data is used to calculate air density and determine the. This results in an increase of fuel being injected into the engine. The manifold absolute pressure sensor map sensor is one of the sensors used in an internal combustion engine s electronic control system.

Take a look at the symptoms and understand why such a problem occurs. New 4928594 4921746 4087989 pressure sensor replacement for cummins exhaust gas. 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. A map sensor that measures high intake manifold pressure indicates high engine load to the pcm.
