Two weeks ago a mechanic replaced the O2 sensor in front of the catalytic convertor because the engine light was on and the engine was running rough. Also, the remote start had stopped working. He also did a complete brake job on the front end. The engine light went off and the engine ran smoothly to Houston & back,700 miles round trip. And the remote start worked again. After returning home and driving around town for a few days the engine light is back on and its running rough again. And the remote start isn't working. Auto Zone code reader showed P0133 and P1134, bank 1 and sensor 1. Both are O2 sensors and one is the same sensor that was changed 2 weeks ago.
I have replaced an O2 sensor and had similar failure after 1500 miles.
I removed it, chkd it, reinstalled it and it ran fine.
P0133 is related to slow response of O2 sensor. P1134 is mfg specific so google that for ur car.

Well, FIRST let me ask you what does B1S2 mean to you?
Bank 1 means it is the same side as the #1 Cylinder
Sensor 2 means it is the Sensor DOWN STREAM or AFTER the Catalytic converter..
With this being said... Are you sure you changed the correct O2 Sensor?
The Second thing that I need to tell you is this... Because it says O2 Sensor. Majority of the time it is the Sensor, but it could be other things... Broken Wire, Computer, Fuel Pressure and if it is DOWNSTEAM... Then it could be the CAT.
THEN.... I looked up and see that it was a HONDA and low and behold it occurred to me...
WHERE DID YOU GET YOUR O2 Sensor From? (this is where I saved so many people)...
Honda has made the variables so TIGHT that an AFTERMARKET O2 Sensor does not work....
If you have a ULEV Vehicle (Ultra Low Emissions Vehicle), you are pretty much forced to get the Sensor from Honda....
That would be my FIRST GUESS.... Get the HONDA Part...
SOURCE: Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1
is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.
Is the wiring good going to the O2 sensors? Maybe just look the car over and see if you have any bad grounds. They can do weird things. Could be a bad ICU.
