How to Install an IAT/MAP Sensor on Ram 3500?

Disconnect the Intake Manifold Temperature/MAP sensor from the negative battery terminal. On gasoline engines, disconnect the electrical connector and turn the sensor counterclockwise. For diesel engines, disconnect the electrical connector and remove the two mounting screws. Inspect the O-ring for damage. Installation is the reverse of removal.

Ram 3500 Intake Manifold Temperature Sensor

The Intake Manifold Temperature Sensor is involved in determining temperature of air being supplied to the engines of Ram 3500 and consequently affects the combustion rates inside the engines. This information is then forwarded to the Powertrain Control Module (PCM) which modifies the fuel injector timings in order to ensure the right A/F ratio is maintained at any operation condition. The Ram 3500 come with different Intake Manifold Temperature Sensors models such as the Mass Air Flow (MAF) sensors, Velocity Air Flow (VAF) sensors. Both types have their own scaling and running properties, on how they felt air and interact with the engine fuel system. An improperly functioning Intake Manifold Temperature Sensor can cause some form of performance problem including stalling or incorrect air/fuel ration and will, therefore, require a detailed diagnosis of the air intake circuit of Ram 3500 vehicles.

Looking for affordable and high-quality auto parts? Then you have already arrived at the proper online shop. We offer all Ram 3500 Intake Manifold Temperature Sensor at great affordable prices. Moreover, all genuine Ram 3500 Intake Manifold Temperature Sensor come with a manufacturer's warranty. In the long run, you would realize you have saved a lot of trouble and money with OEM parts from here.
