How does the p0123 throttle position sensor work?
How does the p0123 throttle position sensor work?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is higher than the normal upper limit, P0123 will set.
What does the trouble code p0123 mean?
Meaning, the PCM (powertrain control module, also referred as ECM or engine control module) has determined the TPS Circuit A output voltage range has gone higher than the sensor’s voltage specification. It’s a generic trouble code, which means it applies to all vehicles made since 1996 to present.
What should I know about my Kia p0123?
If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc.
What is the error code for a TPS sensor?
Error Code P0123 is described as Throttle Position Sensor (TPS)/Switch A Circuit High Input.
Why is my p0123 throttle position sensor not working?
Here are some of the reasons why the P0123 trouble code generates. • Throttle position sensor not positioned correctly. • Throttle position sensor short circuit. • Defective throttle position sensor. • A defective pedal position sensor. • Contaminated throttle body. • Poor or damaged wiring.
What do you need to know about p0123?
Cost of diagnosing the P0123 code. P0123 is a diagnostic trouble code (DTC) for “Throttle Pedal Position Sensor/Switch (TPS) A Circuit High Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

How does the TPS work on a Nissan p0120?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts.
Why does my Wrangler have a p0123 code?
Im working on a friends 1999 wrangler with the 4.0 6 cylinder. I read the resistance of the tps through the operating range and the voltage through the range and it seems to be in spec. The TPS show 15.7% duty at no throttle. Im thinking that the p0123 code is due to a short in the harness/connecter…

What are the symptoms of the p0123 OBD-II trouble code?
The TPS sensor circuit A range output to the ECM went above the specified voltage of 4.54 volts for more than 2 seconds, indicating a short in the sensor or wiring. What are the symptoms of the P0123 code?
The TPS sends the throttle position information back to the PCM on this signal wire. When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts.
