Oxygen Sensor: Description and Operation

DIGIFANT II




Oxygen Sensor

With Digifant II, a separate control unit and frequency valve are not needed. The sensor is connected directly to the Digifant II E.C.U. The control unit uses the voltage signal from the oxygen sensor and adjusts the opening time of the injectors to maintain proper air/fuel mixture.

Digifant II vehicles use a heated oxygen sensor. The sensor is located:

- In the exhaust manifold of the 100 HP engine.
- In the front of the catalytic converter on the 105 HP engine.

Replacement interval for the oxygen sensor is 60,000 miles. A mileage counter and oxygen sensor warning light are no longer used.
