Car runs good need to pass smog getting a P0141 heated circuit (bank 1 sensor 2) I've changed the downstream 200.00 Bosch sensor rest the codes check engin light didn't go off came back on same code when I plug into the obd Innova for emissonand o2 heatr clears but to get the check engin light off you have to reset do cycles all over. Checked ohms on sensor getting 6ohms when check the voltage when it's running its staying right at .40 -.50 doesn't over heat temps normal. I've even unplugged the sensor reset codes then plugged it in and ran little longer same code came back P0141 heated circut (bank 1 sensor2) any one have an idea of what I could be missing to get this code off so I can smog.
