Your car\u2019s TPS \u2018A\u2019 Circuit, like the TPS\u2019 B\u2019 Circuit, has an anticipated output voltage range (if so equipped). When code P0121 appears, it hints that the Engine Control Module (ECM) has detected that the predicted output voltage of the TPS \u2018A\u2019 circuit has gone above or below the sensor\u2019s expected range. When the code activates, your car\u2019s ECM will enter failsafe mode. It could result in limited speeds or acceleration, depending on your car\u2019s failsafe system.
