Code P0153 where are upstream oxygen sensors located at ?
Happy New Year to all and Best of Health,
I have a 2000 Taurus SE V6 OHV with a 184,000 miles with the code P0153.
Code reads Oxygen circuit slow response Bank 2 Sensor 1
Where are the upstream heated oxygen sensors located at?
I had done work on the oil pan gasket and I had taken out all the oxygen sensors and put them back in and I also retightened them. It could be an exhaust leak but since the car has so many miles I wanted to see if it was the oxygen sensors first before spending more on other things.
Thanks and my best to all
