Freeze Frame Data -- When an emissions related fault occurs, the

OBD II system not only sets a code but also records a snapshot of the

vehicle operating parameters to help in identifying the problem. This

set of values is referred to as Freeze Frame Data and may include

important engine parameters such as engine RPM, vehicle speed, air

flow, engine load, fuel pressure, fuel trim value, engine coolant

temperature, ignition timing advance, or closed loop status.
