Help with 1999 ML430 O2 sensor replacemet
I just replaced Bank 1 sensor 2 and Bank 2 sensor 2 and reset the codes. Within 5 miles, check engine light is back on with the same P0141 and P0161 codes
Does anyone know if the computer needs to be reset after changing these or the negative cable removed??? I have NJ inspection in a few weeks.
Thanks in advance..........Mike

Otherwise, I have installed 2 bad sensors, or something else is the problem Don't know what the next step to check is.

The supplier is double checking compatibility and will get back to me.
