Question

Accepted Answer

The throttle position sensor in a 2002 Chevy TrailBlazer can be found on the throttle body of the intake manifold. It's a small, black square piece of plastic with wires attached to it. This sensor is responsible for determining how much throttle you're using while driving, adjusting the throttle body accordingly. If there's a sensor issue, the check engine light on your dashboard may illuminate to alert you. Signs of a faulty throttle position sensor may include slow acceleration and a lack of responsiveness in the throttle pedal. Thankfully, replacing the sensor is a straightforward task that typically costs less than $200.
