Getting these codes may at first look like a disaster that’s going to cost your a fortune. But anytime you get this many codes and they all relate to circuit issues, you can be sure you’ve got a wiring problem and not a massive sensor failure. In this case, start by checking fuse #28 (15A) in the engine compartment. With the key in the RUN position, it should have battery voltage. If so, head for the red wire at the oxygen sensor connections, the transmission connector, and the vapor management valve. They should all have battery voltage too. If the fuse checks out but you don’t see battery voltage at these test points, locate the red wire coming out of the fuse box and check it for voltage. If you don’t see battery voltage there, you’ve got an internal fuse box problem. Some shops are reporting damaged engine compartment fuse boxes. However, if the red wire at the fuse box shows battery voltage, continue to track along the red wire until you find the point where you lost battery voltage.
