specification at heater OFF or it is higher
at heater ON.
Max. voltage of HO2S-2 is lower than
specification or its min. voltage is higher
than specification.
Terminal voltage is lower than
specification at heater OFF or it is higher
at heater ON (or heater circuit or short).

and long terms added) is larger than
specification for specified time or longer.
(Fuel trim toward rich side is large.)
Short term fuel trim or total fuel trim (short
and long term added) is smaller than
specification for specified time or longer.
(Fuel trim toward lean side is large.)
