I am getting P0138, P0158, P0442, and P0456 all at once. I have nothing but trouble for the last 2 years with this issue. I have had the tank dropped for them to replace a sensor, I have replaced a relay in the front, have replaced the gas cap, etc.

I don't know what to do next and I can't afford to send it out again. I manage to get the engine light off long enough to go through emissions. I have spent over $500 dollars on repairs and nothing works.

It seems like every time I get gas and the tank goes below 1/2 tank the light comes on and eventually goes out when it feels like it. I just drive the thing. My husband can repair it if we can find out what the issue is. Any and all help is appreciated. (mielage about 75,000).
