P0124Throttle/Pedal Position Sensor "A" Circuit Intermittent
The TPS signal shows intermittent dropouts that do not stay outside threshold long enough to trigger P0122/P0123. Drive-by-wire systems are sensitive to this and may briefly enter limp-home mode each time.
Can I keep driving? With caution
