Throttle Bodies

Mopar® Throttle Bodies: Controlling Air Intake

You might not think throttle bodies is an important part of your driving experience, but it certainly is. Throttle bodies are the valve assemblies that control airflow into the engine based on accelerator pedal input. These components contain a butterfly valve that opens and closes electronically or mechanically. They regulate the air-fuel mixture for combustion by managing intake volume. Electronic throttle bodies on modern vehicles like the Jeep Cherokee and Dodge RAM 1500 provide precise control for better fuel economy and emissions.

What Causes Throttle Body Issues

Carbon deposits accumulate on the throttle plate and bore from combustion byproducts in the air intake system. Electronic sensors and motors fail from heat exposure and electrical issues. Throttle position sensors provide incorrect readings as they wear out. Gaskets between the throttle body and intake manifold develop leaks. Aftermarket throttle bodies may lack proper calibration or use inferior electronic components. Mopar® throttle bodies maintain strict tolerances and include properly calibrated sensors for accurate performance.

Recognizing Throttle Body Problems

Rough idle and stalling at stops indicate restricted airflow from carbon buildup. Poor acceleration response suggests sensor or motor problems. Check engine lights with throttle-related codes require diagnostic attention. Cleaning the throttle body during regular maintenance prevents many common issues. Replace the throttle body when cleaning no longer resolves performance problems or when electronic components fail.
