Hello,

Im facing an issue with petrol through my LS car.

recently, I had a check engine of o2 sensor ( bank 1 sensor 1 ) .. I replace it with original and the car moves well with an average of 12 L/100km.

the car moves well, but after 3 months I see my car goes back with an issue with a check engine shows an issue with same o2 sensor, I checked it up it gives me that o2 is reading correctly but ( Short shaft term1 ) had an issue with a constant number of 19.5, this number should be between -10 to 10,

the average of my petrol goes to 20+ L/100km which is so high,

does anyone knows whats the issue exactly? Or does anyone faced this issue before ?

Thanks.
