Freeze Frame Data -- When an emissions related fault occurs, the OBD<br />
II system not only sets a code but also records a snapshot of the vehicle<br />
operating parameters to help in identifying the problem. This set of<br />
values is referred to as Freeze Frame Data and may include important<br />
engine parameters such as engine RPM, vehicle speed, air flow, engine<br />
load, fuel pressure, fuel trim value, engine coolant temperature, ignition<br />
timing advance, or closed loop status.<br />
