I have completed a scan of my 1995 Ford contour 2.5 V6. The codes retrieved are the following:
KOEO: 335- Exhst pressure transducer sensor voltage out of range during KOEO.
Mem Code: 172- Lack of heated oxygen sensor switches indicates lean bank 1.
KOER: 336- Exhaust pressure high- Exhaust pressure transducer circuit voltage higher than expected.
Where do I begin looking and what am I looking for to correct these issues? Your assistance is truly appreciated. Thank you.?

First check the exhaust for damaged spots, then the catalytic converter for the " bed" breaking up or melting, and the muffler dor small pieces of the converter bed! If nothing is found, check the EGR position sensor.
