You can look up the error codes on http://www.obd-codes.com.
Because the error codes indicate heater circuit failure.
P0135 and P0155 mean the heater circuits for the front oxygen sensors are not working properly. You need to check the fuse.
#15 under the hood I think.
If that is OK, make sure the exhaust system is grounded. I believe the ground strap is on the back of the cylinder head - right side.
It would be rare that both O2 sensors died again, that quickly. I suspect the dealer didn't really do any diagnostics and just replaced parts (cheap option at least for them).
SOURCE: engine code p0133, p0134, p1133,
All those codes and such an easy fix. ALL of these codes point to your upstream 02 sensor. It's the one on the passenger side of the engine coming off the exhaust, very very easy to get to. Soak that puppy with PB Blaster then remove the electrical connector and remove and replace sensor. TRY to stay away from Bosch 02 sensors, have been known and reported problems with these. In my case, I didn't have a choice but to buy the Bosch, but I haven't had any problems with mine.
Hope this helps, look to get a tad more miles per gallon too.
Testimonial: "Good answer and really appreciate the help. Also was told a PCM recalibration may be needed. Thanks"

SOURCE: Oxygen sensor replacement
It's something you can with simple tools, you have four O2 sensors. Your going to have to get the truck rescanned or if you have the DTC code, you can find out which O2 sensor has gone bad so you can replace it. Your going to have Two upstream O2 sensors on each exhaust bank, one O2 sensor before the Catalytic Converter, and the last one after the Catalytic Converter. Its like replacing a Spark plug and you can pick up the O2 sensor at any large Auto Parts store with a can of WD 40. Just unclip the wire leads to the O2 sensor and then with a O2 sensor socket or hint close end wrench and hammer, you can remove the O2 sensor from the exhaust pipe. Good luck and be safe.
