Question

Check eng light came on scan tool says P0135 code for bank 1 sensor  1  Replaced O2 sensor with new one.  Check eng light came back on after Drive Cycle now Have P0133 code

Answer 1

P0135 H02S heater sensor  heater circuit malfunction  Bank 1 sensor 1

P0133 H02S heater sensor circuit slow response Bank 1 Sensor 1

P0133 is slow response for the 02 sensor , right near the 02 sensor if there is a exhaust leak you set a slow response, A 02 sensor is nothing more than just a negative temperature coefficient. it does not read the 02 content, It measure  heat that is produced by the combustion ,this is what it uses to determine the quality of the combustion. If there is a slight misfire , or misfire the 02 sensor goes slow, for domestic vehicles. Check the coolant level, these intake gasket can seep coolant into the combustion chamber
