I have the printout from my emissions test. It shows some monitors ready, some not ready and some not supported. Does the not supported mean that the 2001 Nissan Maxima does not provide that monitor? The monitors that show ready or not ready are: Catalyst, Evap System, O2 Sensor, Heated O2.

The Catalyst and O2 Sensor are not ready.

 

Before you went for your etest did you happen to clear any CEL issues because if you did you have to complete atleast one drive cycle of about 80km or you are going to always get that the system is not ready on the items you have listed.

 

Where I am at you can pass emissions with one monitor not ready. It might be different for you though.

 

Like Ghost said, you can't just clear a SES light in the parking light before an emissions test and expect to pass. You need to drive the car for a length of time for everything to reregister.

 

I have the same issue before, after replacing the camshaft position sensor and delete the error code , SES light is off but not ready on OBD scan tool.

I did the drive cycle and it works. Read this
