DTC Detecting Condition and Trouble Area
DTC Detecting Condition
DTC will set when one of the following conditions is detected.
• Maximum output voltage of HO2S–2 is lower than specified value
or minimum output voltage is higher than specified value while
vehicle driving.
• Engine is warmed up and HO2S–2 voltage is higher than speci-
fied value (circuit open)
(2driving cycle detection logic)
DTC Confirmation Procedure
WARNING:
• When performing a road test, select a place where there is no traffic or possibility of a traffic acci-
dent and very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 person, a driver and tester, on a level road.
NOTE:
Check to make sure that the following conditions are satisfied when using this DTC CONFIRMATION
PROCEDURE.
• Intake air temp.: –7°C, 19.4°F or higher
• Engine coolant temp.: 70°C, 158°F or higher
• Altitude (barometric pressure): 2500 m, 8200 ft or less (540 mmHg, 72 kPa or more)
