U0124 Does not exist

There is no information on this.The code you are looking for is P0123 Throttle/pedal position sensor switch"A" circuit high input, P0124 Throttle/pedal postion sensor switch "A" intermittent.. The throttle position sensor is mounted on the throttle body it detects the opening of the throttle valve, When these code come on The ECM enters into a fail safe mode,which is a set idle and RPM.The failsafe continues until the ignition switch is turned off.The replacement of the TPS is the solution,
