Check engine light warnings

The check engine light is a crucial indicator of potential throttle body issues. Common diagnostic trouble codes (DTCs) related to throttle body problems include:

• P0121: Throttle Position Sensor Circuit Range/Performance Problem

• P0122: Throttle Position Sensor Circuit Low Input

• P0123: Throttle Position Sensor Circuit High Input

Regular vehicle maintenance and prompt attention to these warning signs can help identify throttle body issues early. If you experience any of these symptoms or your vehicle falls within the age and mileage ranges mentioned, it’s advisable to have your throttle body inspected by a qualified mechanic.

Now that we understand when to consider replacing your throttle body, let’s delve into the replacement process itself. This section will explore the various aspects of throttle body replacement, helping you make informed decisions about this crucial maintenance task.
