Why Care About Your 5.9 Cummins TPS?

Before we dig in, let's understand why the TPS is so important. This sensor tells your engine's computer (ECM) the position of the throttle plate in your truck's throttle body. Based on this info, the ECM adjusts the fuel injection to maintain optimal engine performance. A bad TPS can cause a slew of issues, including:

- Check Engine Light - Rough Idle or Stalling - Poor Acceleration - Decreased Fuel Economy
