2018 Infiniti QX30 Premium (Mother's Car)
This is what my invoice said when I had the issue.This is what the Invoice said:
"Confirmed light on with codes P2138 for the throttle position sensor. Completed inspection of the terminal connectors between the accelerator pedal throttle sensor and the ECM. Found pins 4 and 5 at the throttle sensor to have loose fit. Replaced the connector and terminals at the throttle sensor for better connection. Cleared the codes and test drove for 25 miles to confirm the light is off and it is now running normally".
