Code P0121 on a 2004 Kia Spectra indicates a problem with the Throttle Position Sensor (TPS) circuit. This could be due to a faulty TPS, a wiring issue, or a problem within the engine control module (ECM). The TPS is responsible for monitoring the position of the throttle plate and relaying that information to the ECM, which adjusts fuel delivery and engine performance. If this code appears, it’s advisable to inspect the TPS and associated wiring for faults.
