3. Heated Oxygen Sensor Monitor (P0130, P0136)
TEST CONDITIONS/PROCEDURE1. All of the following conditions should be satisfied when the drive test is carried out.
a. Engine coolant temperature: 80° C (176° F) or more (when engine is fully warmed up)
b. Outside air temperature: 10° C (14° F) or more
c. A/T condition:
- Selector lever position: D range
- Overdrive switch: ON
- Power/economy changeover switch: Power
2. Carry out one trip monitoring according to the following drive pattern (from starting of the engine until ignition is turned off). (Takes approximately 5 minutes.)
a. After the engine is fully warmed up, turn the ignition switch to OFF.
b. Start the engine and accelerate to a speed of between 56 - 64 km/h (35 - 40 mph).
c. Monitoring period: drive for 120 seconds or more while maintaining the throttle opening angle at a constant angle (keeping throttle variations as small as absolutely possible) and the vehicle speed at between 56 - 64 km/h (35 - 40 mph). Drives as consistently as possible during this time, without making any sudden steering wheel movements.
d. Decelerate to a stop. After the vehicle has stopped, turn the ignition switch to OFF.
