Heated Oxygen Sensor Monitor

Test conditions and main points to note:
1. Conduct test drives in a manner that will ensure all the following conditions are met:
1. Engine coolant temperature: 80 °C (176 °F) or higher (with the engine fully warmed up).
2. Outside air temperature: -10 °C (14 °F) or higher.
3. Selector lever position: D range.

2. The following drive pattern (from start up to when the ignition is turned off) completes one trip monitor (Time required is approximately 5 minutes.)
<>1: After the engine is completely warmed up, turn off the ignition.
<>2: Start the engine and accelerate quickly until speed reaches 56 - 64 km/h (35 - 40 mph).
*3: Monitoring period: keep throttle open at a uniform level (minimize throttle variation) and drive for 120 seconds or more at 56 - 64 km/h (35 - 40 mph). Drive steadily during this period, without sudden turning of the steering wheel.
<>4: Decelerate and stop the vehicle. After stopping the vehicle, turn off the ignition.
