i replaced my front o2 sensor after the p1133 code i had. now 2 weeks later i get a P0141 code. can anyone give me a little more insite into this code. thanks

That code should be for the rear O2 sensor

thanks for that info. now i have a zzp rear o2 sim. in place of rear sensor. i have had that for over a year now with no problems before. is it possible the sim is going out the window?

I think it would be safe to say its no longer working. Might want to check to see if the connection to the sensor is still good.
