The GMC Sonoma Throttle Cable is the physical connection from the gas pedal to the throttle plate of the truck. It gets the engine to respond to how much pressure is put on the gas pedal with accurate engine air flow. Comprising several metal strands woven together, this Throttle Cable pulls the butterfly valve open when the pedal goes down, allowing more air into the intake manifold while the PCM enriches the fuel flow synchronously. The throttle body injection applied by the early GMC pickups was a simple cable system. This allowed these pickups to start easier and get better mileage. It also avoided the added complexity of electronics. Later GMC Sonoma models gradually applied electronic throttle control. This replaced the Throttle Cable with a series of sensors and electric motors to integrate traction and stability functions. However, the mechanical cable remained common on many versions through the 1990s. The Throttle Cable has to move freely, whether it connects to a single throttle body on TBI engines or to a multi-port setup, since sticking or fraying delays plate closure and raises idle speed. The driver of the Sonoma must enjoy a predictable feel from the accelerator pedal, which requires a simple but effective design. A worn Throttle Cable will usually give increased pedal effort or a sluggish return. This indicates it is time for replacement to restore factory pedal response.
