Generic OBD II Parameter Identification (PID) List - Part 2 Of 2:
NOTES
[1] = Individual oxygen sensor fuel trim adjustment is not supported.
[2,3,4] = Individual oxygen sensor fuel trim adjustment is not supported.
[a] = OL - Open loop, have not satisfied conditions for closed loop.
[b] = Percent engine load adjusted for atmospheric pressure.
X = Freeze Frame PID
CL = Closed loop using oxygen sensor(s) (O2S) as feedback for fuel control.
OL DRIVE = Open loop due to driving conditions (heavy acceleration.).
OL FAULT = Open loop due to vehicle system fault.
CL FAULT = Closed loop fuel control, but fault with upstream O2S.
