How do I properly diagnose my codes in my 2010 Nissan Maxima.

Asked by Author Eric Aug 27, 2022 at 02:20 PM about the 2010 Nissan Maxima S

Question type: Maintenance & Repair

I’ve changed all my o2 sensors and purge valves on
my 2010 Nissan Maxima but I’m still getting a 07e8
and 0443

Did you clear the computer after the repair? You should have. If you did and the trouble codes came back the problem is most likely with the wiring going to the sensors. The EVAP system diagnostics will not run if the gas gauge is above the three quarters full mark or below the one quarter mark. Did you test the gas cap? That could cause an EVAP code too. Hope that helps! Jim
