Which rear sensor did you replace? (This vehicle has 2 converters). Did you clear the codes after you replaced the sensor?
THe P0139 and P0038 are pointing to the same sensor (one is heater malfunction, one is general malfuntion). The exhaust system should look like this:
So if you changed the passenger side, you need to change the driver's side, rear sensor. If your setup does NOT look like this, then you need to check your fuses for any that are blown, and I would also reset the computer. You can do this by removing the "NEG" cable from the battery for 15min. After the code is cleared, if there is still a problem, the Check Engine Light should return within 50-75 miles of normal driving (if not less if the "heater" for the O2 sensor is still faulty)
Unfortunately, all correspondence must be done through this JA message forum, JA rules. I will re-send it. Click "View Full Image" link under the pic for a pop-up window with a close-up view (the sensor you need to change has the red arrow).
Thanks. I will take your advise.
Ok. Glad I could help. Have a great day. Good luck. If you need me, you can find me here.
