Question

obd code p0135 and causing too much fuel consumption...

Answer 1

P0135 02 sensor heater circuit malfunction Bank 1 Sensor 1

What you have equipt for Bank 1 is referred to as a oxugen sensor but it  is a Airflow sensor. When the airflow sensor does not work properly you will use more fuel than required, the best fix is to replace the airlow sensor.

 Here is a 02 sensor that coded a P0135 you can see the excessive fuel use on this vehicle. When P0135 occurs the airflow or 02 sensor can no longer maintailn fuel control.
