DETECTING CONDITION
(DTC will set when detecting:)
Sensor output too low
Sensor output too high
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-1 is higher
than specification.
Max. output voltage of HO2S-1 is 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
open).
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.
Min. output voltage of HO2S-1 is higher
than specification.
Max. output voltage of HO2S-1 is lower
than specification.
