Just got a 2002 maxima and engine service light came on

p0152 is bank 2 sensor 1 oxygen sensor code...make sure it was plugged back in or sensor may need replacement or you may have damaged the harness. p1564 is for the automatic speed control device basically the same possibilities with this circuit.

Check for any loose wire harness connection or bad contacts.

If is is only smoking when you first start it up. Most likely the valve guide seals, oil is leaking into the cylinders and smoking when you start it up.

Here is the location....

I know common issues for the the 2000 Maximawas the Mass Air Flow sensor and the coils. I think both of them triggered a Service Engine Soon light.

My 2002 Maxima has had no issues yet (only 70k miles, unlike the 180k on the 2000).

any or all of these problems could illuminate the mil

Stop in at autozone or similar autoparts stores & get free scan to see what code is stored & go from there.

First thing I would do is make sure you battery cables have a flawless connection. I had a Honda with a similar problem. I changed the battery cable and it all went away. Like magic. Sometimes these can be a simple fix.
