Folken,
для машин до '93 параметры и условия, при которых комп проверяет правильность работы лямбды:
3 minutes have passed after engine was started.
Engine coolant temperature is approx. 80°C (176°F) or more.
Intake air temperature is 20-50°C (68-122°F).
Engine speed is approx. 1,900-2,200 r/min.
Vehicle is moving at constant speed on a flat, level road surface.
Ошибку на него выдает при всех достигнутых условиях при "The oxygen sensor output voltage does not cross specified voltage for specified seconds."
для машин после 94 условий проверки больше.
подогреватель начинает проверяться c начала движения до достижения скорости 35 миль/ч:
"Background:
The engine control module checks whether the heater current is within a specified range when the heater is energized.
Range of Check, Set Conditions:
The oxygen sensor heater current is either lower than several dozen milliamperes or higher than several amperes."
