Is your 2002-2004 Toyota Tacoma with the 3.4L V6 engine acting up – maybe hesitating on acceleration, idling rough, or throwing a check engine light (often P0120, P0121, etc.)? A failing Throttle Position Sensor (TPS) could be the problem. This sensor tells your truck's computer how far the throttle plate is open, which is critical for fuel delivery and engine performance. This is a direct-fit OEM replacement designed for Tacomas built from September 2002 through August 2004. It's compatible with a wide range of models from that period, including 4WD, PreRunner, S-Runner, and various cab styles, as long as they have the 3.4L V6. Always double-check your truck's exact production date and model before ordering. Replacing the TPS is usually a simple job (often just two screws and an electrical connector) located on the side of the throttle body. Swapping in a new, reliable sensor can restore smooth throttle response and drivability.
