When should you replace the Throttle Position Sensor?

You should replace the Throttle Position Sensor (TPS) if you experience symptoms such as poor acceleration, inconsistent engine idle, or difficulty in maintaining speed. Additionally, check engine lights related to throttle issues or trouble codes indicating TPS malfunction are strong indicators for replacement. Regular maintenance checks can also help identify wear or malfunction before these symptoms become pronounced. If the TPS is found to be faulty during diagnostics, it's advisable to replace it promptly to restore optimal engine performance.
