What is your question?
CEL on, OBDII error code P0151/P0155. I purchased a Bosch O2 sensor, part #15430, which is for the front manifold, upstream of the catalytic converter. I want to make sure I purchased the correct part.

I have a 2004 Mazda 6 3.0 L fault code 2197 02 sensor signal stuck lean bank 2 sensor is this the 02 sensor in the front of the engine?
