I have a car that works with petrol and gas. When I start the engine I get this alarm "heated oxygen sensor (HO2S) 1 Bank 1 - heater voltage low ". I reset the alarm with OBDII program and the alarm disappear and I can work with gas, but when I turn off the car and start again the alarm come again and I cannot work with gas any more only with petrol. Sometimes when I work in gas after alarm reset the car need too much gas to run because it turn off. I have also changed the sensor of HO2S but still the same.
Can you give me advise what can I do with this?
I have control the gas electrical packet and I have make some proves and than I heard something inside of gas packet like a burn noise. Now I can't work in gas any more and the level of gas is not anymore displayed in car display. What has happened?
I have change the air-fuel rate sensor. Should I change the sensor to the catalytic too?
Thank you.
