hi guys. wondering if you can help me. My husband (apex i itr) is on his way home and my car threw a code 43. Does anyone know how to remedy this? We know that it's a fuel system issue but we're not sure which part. Thanks in advance

 

i accidentally disconnected my o2 sensor one day and code 43 came up along with the o2 sensor.
so i would check the o2 sensor to see if its acting up first.
this happen both times i messed with my o2 sensor

 

well code 43..... well everytime i got taht code... ti has been a o2 sensor..... if u have an extra one.. pop it in and see if it works...

 

thanks guys. After he pulled the code it went away. I know we were having issues with the O2 sensor in the past .
