How to Install a Throttle Body on a 5.7L Engine on Dodge Ram 2500?

Before installing the throttle body on a 5.7L engine, see if the O-ring is in good shape, clean the throttle body and clean the underside of the intake manifold. Then, fit O-ring 2 between the throttle body and intake manifold and set the throttle above the manifold alignment pins. Using your fingers, limit the tightness of all the mounting screws. Proper care should be taken to tighten the throttle body bolts only as much as the instructions advise or else the throttle body or intake manifold could be damaged. Use a torque wrench to tighten the screws in the pattern described below to 5.6 Nm (50 in. lbs.). Afterward, attach connector 2, connect the air plenum to flange 3 and connect the negative battery cable. Finally, wipe out all previously saved codes and run the ETC Relearn feature with the diagnostic scan tool.

The Throttle Body was designed for controlling the airflow into the engine of the Dodge Ram 2500 thus controlling the performance an fuel economy of the vehicle. Incorporated into its design is a butterfly valve that is controlled by the accelerator pedal and receives signals from the TPS and MAF and delivers them to the PCM of the powertrain. The pictures portray this system as a means, through which accurate adjustments of the air-fuel mixture can be realized - this is crucial for smooth operations to be effected. It is interesting to note that Dodge Ram 2500 for many years has adopted both the mechanical and the electronic throttle control. The "drive-by-wire" method by the application of the sensors firms up the communication between the car and the ECU. Conventional throttle bodies are used while some car makers utilize individual throttle bodies (ITBs) for better flow rate which are scarcely used in standard models. It is important to clean the throttle body frequently as this is almost always damaged, clogged, or worn out that might cause problem with the vehicle idling, accelerating or even the fuel consumption of the Dodge Ram 2500 car.
