CHECK ENGINE LIGHT

1998 Mazda Millenia

Electrical problem
1998 Mazda Millenia 6 cyl Four Wheel Drive Automatic 63000 miles

I have a check engine light pop up again.
I had repairs last year for this check engine light with codes P0300, P1170, and P1173 with a major tune up (brakes/spark plugs/NDK wire replaced) for $1200. This fixed it, I passed the emissions and moved on.

Now the light is back. The new codes that came up are P1170-H02S11 and P1173-H02S21. What does this mean and what do I need to get this fixed? Is is worth getting it fixed or just selling the car if possible.
