2002 Saturn Vue 3.0L 6Cyl Fault Codes P0638, P2101, P2119, P2176 - Loss of Power Below 2000 RPM

Hello everyone! I'm hoping for some help with my 2002 Saturn Vue 3.0L 6-cylinder engine. A few days ago, my car started showing a loss of power and reduced performance—engine will not exceed 2000 RPM under load. The onboard diagnostic system has triggered the following fault codes: - P0638: Throttle Actuator Control Range/Performance (Bank 1) - P2101: Throttle Actuator Position Performance - P2119: Throttle Body Throttle Actuator Control Range/Performance - P2076: Minimum Throttle Position Not Learned I'm new to automotive diagnostics and want to understand whether these codes point to a common issue—such as a faulty throttle body or actuator—and if I should repair or replace components. All the codes relate to throttle control systems, suggesting potential problems with the throttle position sensor(s), actuator, or wiring. Since multiple codes are related to throttle performance, it's likely that one component (like the throttle body or actuator) is failing and affecting engine response. I'm looking for clear guidance on what steps to take next—whether to repair or replace parts—and how these codes interrelate in a 2002 Saturn Vue with a 3.0L V6 engine. Any insights from experienced users would be greatly appreciated! Thanks in advance.
