1. Throttle Position Sensor (TPS): This is a sensor that measures the throttle plate position and sends that data to the PCM (Powertrain Control Module). It's usually a multi-pin connector.
2. Idle Air Control (IAC) Valve: This valve controls the amount of air bypassing the throttle plate at idle to maintain a consistent engine speed. It's usually a single-pin connector that goes to the IAC valve itself, and the valve is integrated with, or very close to, the throttle body.
3. Throttle Position Sensor (TPS) and/or MAP (Manifold Absolute Pressure) Sensor Power and Ground: Often a single connector may contain power and ground wires along with signals from the TPS. Some TPS sensors have a dedicated ground while others get it from the main connector. A MAP sensor may also be included in a combined connector.
Important Note: While these are the *usual* suspects, the exact configuration might vary slightly depending on the specific year and model of your Jeep. It's always best to consult a wiring diagram specific to your vehicle's year and model for absolute certainty. You can often find these diagrams online or through a repair manual.
