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.
What causes low voltage on TPS?
The voltage of the throttle position sensor can drop below the expected range for several reasons, including the following: A loosely-mounted throttle position sensor. Electrical short on the sensor circuit, either to the ground or to another wire. Faulty sensor.

- Rough Idling:
- Your vehicle doesn’t accelerate over a specific limit:
- The engine does not run effectively:
- Inconsistent acceleration:
- Poor automatic transmission shifting or jerks when depressing the throttle pedal:
- Check engine light:
- Locate the APP sensor:
Do you have to calibrate a new TPS sensor?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to “TPS Raw” in the Analog Settings.
What happens when a TPS sensor goes bad?
When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won’t start.
