Generic OBD PID List
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2009 Mercury Mountaineer, 2009 Mercury Milan, 2009 Mercury Mariner, 2009 Mercury Grand Marquis, and 2009 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
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 one upstream HO2S sensor on dual bank vehicles. |
