OXYGEN SENSOR PROBLEM

2007 Honda Accord

Electrical problem
2007 Honda Accord 6 cyl Front Wheel Drive Automatic 50000 miles

I have had P0154 P0135 I have replaced those sensors with honda sensors. The check engine light is still on. I took it to a shop and they told me they could not find the problem. They tested the sensors and there in good condition they said the problem could be because there is no power to my oxtgen sensors. Is there a fuse Relay someplace that I can check? Or is there something else there can be checked?

Ok for code P0135 check these fuses. Fuse number 4 (af sensor) 15 amp in the fuse box under dash. Fuse number 19 40 amp in the fuse box under the hood. Fuse number 23 7.5 amp in fuse box under dash. This could also be what is causing the P0154 code too. Let me know what you find and we will go from there.

I tried checking all those fuses and they are all in working condition. What else could it be?

Ok now I need you to unplug the mass air flow sensor and use the pic below to check ohms between term 3 and 4 on the sensor not the wiring harness. Is the ohms between 2.1 and 2.9? If not then replace the mass air flow meter.
