I purchased the car listed above. Flex fuel from sister-in-law that had been wrecked in front end. Her husband put most of car back together, he couldn’t get it to run without going into limp mode. I put new battery in and now drive about twelve miles and goes back to limp mode. The dash reads loss of power, service esc, and service traction. I hooked up my code scanner and got codes P0068, P0030, P0036, P0102, P0135, P0141, and P0443. I replaced both 02 sensors, MAF sensor and throttle body. No matter what I do same codes with the same outcome twelve miles limp mode. Always same codes, please help.

I am wondering if the grounds are all connected to the engine and radiator support panel after the accident repair. Here is the location of the grounds so you can confirm the connections. Also, clear the codes then turn the key on without starting the engine to see what codes come up, these codes are hard codes which can help us fix it. Check the ground diagrams below, these are very important. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
