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.
