2000 Maxima service engine soon.

What will really grip your butt is that the Air Flow Sensor for this
car can be had for about $110. See this site.

That was on the list of "probably causes" I sent you (from the FSM).

from other mechanics was "well we'll replace this and that..."

Its technical because there are over 300 different error codes that
can cause the check engine light to come on,,,,,,,!!!

If you do not like the light, and do not want to fix the problem, then
take the bulb out of the light - thats your "non technical" fix.

Dont dump on someone who tried to give your the correct answer,,,,,

But the guy at AutoZone could not tell me if the problem was an oxygen
sensor (much less which one) or anything else.

My 2000 Maxima with 80,000 miles just had the service engine soon

No way of telling without knowing the code(s) that have been set.
Could be
most anything.
PO171
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual
mixture ratio can be brought closely to the theoretical mixture ratio
based on the mixture ratio feedback signal from the front heated
oxygen sensors. The ECM calculates the necessary compensation
to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large
(The actual mixture ratio is too lean.), the ECM judges the condition
as the fuel injection system malfunction and light up the MIL

Malfunction is detected when fuel injection system does not operate
properly, the amount of mixture ratio compensation is too large.
(The mixture ratio is too lean.)
Possible Cause

I Intake air leaks
I Front heated oxygen sensor
I Injectors
I Exhaust gas leaks
I Incorrect fuel pressure
I Lack of fuel
I Mass air flow sensor
This is interesting but highly technical information that goes over
the head of the average owner.

Any other "average owners" out there who have found solution to the
"service engine soon" light?

BTW. Mine is a 99 Maxima GLE.

It was - it was nice to have a dealer do the up front diagnostic work to
determine what the problem was instead of just replacing parts like other
mechanics wanted to do. (Maybe the extra $ is worth it after all......)

I saw your answer to the poor soul who wanted non-technical input from
other members.

"Dump"???!!!!!

That's pretty unfriendly.

So you want a non technical answer to a highly technical problem?

I dont think "dump" was to harsh. One other poster spent his time to
type up an entire page of possible "technical" issues that could have
been the problem.

The response back was "oh thats to technical" can anybody just tell me
how to make the light go off.

The non technical way to get the light to go off is to take it to the
dealer. Only the dealers have the expertise and equipment to work of
these cars.

I was among several who raised the original issue. I guess I was
trying to ask whether the light is a real warning or just a buggy
light. The fact that several owners of this model report the same
phenomenon made me wonder if there is a real problem. Taking the bulb
out is closing one's eyes to the issue. Some people can't afford a
big dealer bill for what might be a chimera.

Pax!
