Mazda 323 BA Astina 1997, 1.8L , New Bosch Oxygen sensor in action.

Description

Mazda 323 BA Astina 1997, 1.8L , New Bosch Oxygen sensor in action. The engine is idling and bar graph indicates the sensor output voltage fluctuation between 0 and 0.9 volts. When voltage is close to zero the engine is running lean and when close to 0.9 its running rich. When cruising it fluctuates fast. Good indication that your injectors are working well and your intake air system is good. The ideal fuel/air mixture is when sensor voltage is 0.45V but this is very momentary and your ECU cant sustain it at that level, hence the fluctuation. Asanga Gunatilake
