I have two check engine lights P0138 and P2096 on my brother in law's 2013 Ford Explorer V6. Any ideas what this could be?
here you go:
P0138
Causes A code P0138 may mean that one or more of the following has happened: Faulty O2 sensor Short to battery voltage in O2 sensor signal circuit High fuel pressure (not as likely)
Possible Solutions Here are some potential solutions: Replace O2 sensor Repair short to battery voltage in o2 sensor signal circuit
P2096
Potential Causes The causes for this DTC may include: Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors. Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0304 for number 4. A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture. A large air leak at or near the number one oxygen sensor would also cause a lean mixture. A plugged converter will cause of host of driveability problems as well as set this code. A severely plugged converter will result in the inability to increase rpm when under load. Look for a code such as P0420 -- catalytic converter efficiency below threshold if the converter indicating a faulty converter.
A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area. The Mass Airflow sensor will also cause this problem. It would be accompanied by a code such as P0100 -- Mass Airflow circuit malfunction. The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture. Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks. To make a point as to the cause and effect on vehicles, consider this scenario. A simple air leak forward of the number one oxygen sensor will add additional air to the mixture un-metered by the computer. The oxygen sensor signals a lean mixture due to the un-metered air. Immediately the computer enriches the mixture to prevent a lean mixture from causing damage due to detonation among other factors. The unnecessarily rich mixture begins to foul the plugs, contaminate the oil, heats up the converter and drops the fuel economy. These are only a few of the things that transpire under these circumstances.
quick google search came up with the following. Based on the codes it sounds like you need to replace the rear of the catalytic converter oxygen sensor followed by a reset of the computer (unplug battery for 10 minutes). Should fix your problem. Here is a link to a part:

Don't forget to google a discount code and you should be able to get it for like 50-60 bucks. As its rear of the cat it should be a really easy job for you to tackle yourself.
