Question

I owned a golf 1990 cl 1.3 fuel injector , is the OXYGEN SENSOR important for it to reduce fuel?

Answer 1

Yes, the readings from the O2 sensor tell the engine management what adjustments to make to the amount of fuel it injects. If there is no signal from the O2 sensor, the E.C.M goes into a 'default' mode where it injects a bit more fuel than it thinks you may need, to avoid lean running and detonation. So if your O2 sensor is not working, your fuel consumption will go up.

Answer 2

Yes.Fuel and oxygen intake combined tell the right mix for the car.

Answer 3

Yes the oxygen sensor, also known as the o2 sensor, is very vital in the reduction of fuel. the oxygen sensor in newer, after seventies model cars, takes the place of calibrating the carburator. The oxygensensor tells the engine how much oxygen to pull in relation to fuel, if that is out then your exhaust fumes are probably horrible and your gas consumption isnt astronomically high but it could be much better with an oxygen sensor.
