Hello from Poland,
I have an issue with P2138 DTC. Accelerator pedal and throttle body have been changed. Now I am trying to perform idle learn procedure.
But, on "DATA DISPLAY" card I have red line indicator by the "CLS THROTTLE" , and parameter value is "ON".
What does it mean? What should I do with the throttle?
PS. The car is Nissan Altima L31, QR25DE engine.
