Generic OBD PID List
WARNING: This page is about a different variant/trim than selected.
An X in the Freeze Frame column denotes both a mode 1 and mode 2 PID (real time and freeze frame).

CL = Closed loop using HO2S(s) as feedback for fuel control.
OL DRIVE = Open loop due to driving conditions (heavy acceleration).
OL FAULT = Open loop due to fault with all upstream HO2S sensors.
CL FAULT = Closed loop fuel control, but fault with 1 upstream HO2S sensor.
