DTC P0133: O2 Sensor (HO2S) Circuit Slow Response (Sensor-1)
Wiring Diagram
Refer to "DTC P0131 / P0132 / P0134: O2 Sensor (HO2S) Circuit Low Voltage / High Voltage / No Activity Detected
(Sensor-1): For Petrol Engine Model".
A/F Sensor Description
Refer to "A/F Sensor Description: For Petrol Engine Model".
DTC Detecting Condition and Trouble Area
Ratio between integrated value of A/F sensor output variation and integrated value of
short term fuel trim variation is more than specification while vehicle is running
constant speed and low engine load after warmed up.
(*2 driving cycle detection logic, monitoring once / 1 driving)
DTC Confirmation Procedure
WARNING
!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out by 2 persons, a driver and a tester, on a level road.
NOTE
Check to make sure that following conditions are satisfied when using this "DTC Confirmation
Procedure".
• Intake air temperature at engine start: –10 °C (14 °F) to 80 °C (176 °F)
• Intake air temperature: –10 °C (14 °F) to 70 °C (158 °F)
• Engine coolant temperature: 70 °C (158 °F) to 150 °C (302 °F)
• Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Start engine and warm up to normal operating temperature.
4) Drive vehicle at 40 mph (60 km/h) or higher. (engine speed: 2500 – 3000 r/min.)
5) Keep above vehicle speed for 6 min. or more. (Throttle valve opening is kept constant in this step.)
6) Release accelerator pedal and with engine brake applied, keep vehicle coasting (with fuel cut for 3 sec. or more)
and then stop vehicle.
7) Check if DTC and pending DTC exist by using scan tool. If not, check if oxygen sensor monitoring test has been
completed by using scan tool. If not in both of above checks (i.e., no DTC and pending DTC and oxygen sensor
monitoring test not completed), check vehicle condition (environmental) and repeat Step 3) through 6).
