Maximize Your Potential with p0123 The Ultimate Guide for Professionals

The P0123 code means the PCM sees the voltage as too high in the TPS circuitry. The TPS uses the 5 volt reference circuit to provide it's signal to the PCM. The reference voltage should be 5V. The reading at idle should be .6V. The WOT reading should be above 4.0V, but when it goes above 4.75V, the DTC gets set. Dodge/Ram Diesel Tech - DTC P0123 Throttle/Pedal Position Sensor A Circuit High Input - Can anyone explain what might be the cause DTC P0123 ... I get these error codes P0123, P0223- which involve the drive By wire pedal sensor And high circuit voltage. is thus a wiring issue I should be checking before ... Code P0123 may be triggered when your car computer receives a signal from the TP sensor that exceeds the maximum limit for a set period. Code P0123, which is a high TPS voltage. I used my meter and check the voltage and the car is reading at 4.8v at pin 3 and around 5.0v at pin 1 which is over ... The code is TPS related so a new throttle body should fix the issue since it is built in to the throttle body itself. Code reads 0123 - Throttle/Pedal Position Sensor/Switch A Circuit High Input. Along with this code I have some downstream sensor circuit codes. The only code it gives me is p0123. Does anybody know if the throttle position sensor is reading too high would that cause the PCM not to let the car start? It doesn't respond to inputs at the gas pedal like it should. It has a VERY slow response, making the car extremely sluggish and dangerous to drive.
