    CEL codes help

    Alright guys I got a couple of cels while going to reno Nevada today when I got to the summit of over 7000 feet it came on I pulled over shut it off and it went away until the way back it came on again at the same spot, I just checked and the codes read 41 being primary oxygen sensor heater and code 43 which is fuel supply system? I just need help figuring out what to fix or check.

    what i read in the past,was that if you get CEL code 41.it could also turn on CEL code 43..i do get the same problem with my prelude si.i do know that my O2 sensor is giving up.some times it would go away and when i jumper the service connector,it throws 41 and 43 at the same time.when i checked it the next day,it was only 41..
