DTC
P0123
Electronic Throttle Position Sensor 1 Circuit High Voltage
TPS1 sensor sends signal through ECT harness connector EO27 terminal B to ECM through ECM harness connector EO01 terminal
No.39. If the TPS1 sensor signal is lost, but ECM is able to receive the normal TPS2 sensor signal, then ECM controls the engine
enter "reliability of determining the driver's intention decline or no high power output mode". Engine responds to the pedal changes
