Details of the Audi p0122 OBD Code
Audi P0122 code indicates an issue with the throttle position sensor circuit low input.
OBD code P0122 for Audi vehicles indicates an issue with the Throttle Position Sensor/Switch A Circuit Low Input.
This code is triggered by the Engine Control Module (ECM) when it detects that the voltage signal from the throttle position sensor is lower than expected.
The throttle position sensor is responsible for monitoring the position of the throttle valve and sending this information to the ECM to adjust fuel delivery and ignition timing.
When the voltage signal is too low, it can lead to drivability issues such as poor acceleration, rough idling, or stalling.
Mechanic’s Tech Notes
Troubleshooting notes for Audi P0122 code related to throttle position sensor low voltage.
To diagnose and fix OBDII code P0122 on an Audi, start by checking the throttle position sensor (TPS) circuit.
Use a voltmeter to test the TPS signal voltage with the key on, engine off.
It should range from about 0. 5 to 4. 5 volts smoothly as the throttle is opened and closed.
If the voltage is out of range or erratic, the TPS may need replacement.
Additionally, inspect the wiring harness and connectors for any damage or corrosion.
Ensure the TPS is securely mounted and aligned properly.
Clear the code after any repairs and recheck to confirm the issue is resolved.
