A Throttle Position Sensor (TPS) is a critical component in your vehicle’s engine management system. It monitors the position of the throttle plate (the valve that controls the engine's air intake) and sends this information to the engine control unit (ECU). The ECU uses this data to adjust the air-fuel mixture and manage engine performance, including acceleration and idle speed.
Here’s when you might need to replace the TPS:
- Engine Performance Issues: If you notice symptoms like erratic idling, poor acceleration, or stalling, a faulty TPS might be the cause.
- Check Engine Light: If the check engine light comes on and a diagnostic scan points to the TPS, it may need replacing.
- Unusual Throttle Response: If the throttle feels unresponsive or inconsistent, the sensor might be malfunctioning.
- Inconsistent Idle: If the engine idle speed fluctuates or is unstable, it could be a sign of a TPS issue.
