code 41 help
 

i have a 94 ex and i had a test pipe on it.. i put the cat on to get it inspected a code 41 popped up.. the o2 sensor was pretty old so i replaced it. the code is still coming up. if the car is cold it comes on but if i let it warm up and turn it off then turn back on it wont come on any one kno wat could cause this

Code 41 is for the pre-heater in the O2 sensor. Since you already put a new sensor in, now you should look for wiring problems in that heater circuit.
