code 41- Primary Oxygen sensore. Code 43 Fuel supply..... I just replaced my 02 sensor like a week ago and ran my codes to see if there are any stored and they came up.. I had code 1 and 43 before and i heard that 43 can be caused by a bad 02 sensor. Well i replaced the o2 sensor and now it says 41 and 43... Any ideas why it would be throwing them???

 

your o2 sensor maybe? was it a bosch replacement?

 

idk if it was boshe but it was 100 bucks with the pin connector....
