DETECTING CONDITION
(DTC will set when detecting:)
Sensor output low voltage (or MAF sensor
circuit shorted to ground)
Sensor output high voltage (or MAF sensor
circuit open)
Intake air temp. circuit low input
Intake air temp. circuit high input
Engine coolant temp. circuit low input
Engine coolant temp. circuit high input
Throttle position circuit low input
Throttle position circuit high input
Poor performance of TP sensor
Min. output voltage of HO2S-higher than
specification
Max. output voltage of HO2S-lower than
specification
Response time of HO2S-1 output voltage
between rich and lean is longer than
specification.
Output voltage of HO2S-1 fails to go above
specification (or HO2S-1 circuit shorted to
ground).
Terminal voltage is lower than 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)
Short term fuel trim or total fuel trim (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.)
