go to an auto zone or advanced auto parts
and they will read the code for free.

Some of the Nissans have the ECU unit (computer) located under the
passenger's front seat. Then to read that code you would need to turn your
ingnition ON (but don't start the engine) and turn a screw on the side (of
some) ECU units and hold it until the "check engine" indicator light begins
to flash. You'd need to turn the screw (on the ones I've seen in the late
1990s) fully clockwise and hold it there - but only turn it gently. Then the
check engine light will start to blink and you let go of the screw.

You may have either to 2 digit code or only the one digit code - but I think
yours might be 2 digits. You need to count those flashes. There will be a
pause between the 2 different numbers, first number and 2nd number.  If you
turn the ignition OFF - that should make it so you'll only see a regular
check engine indicator when it restarts - no flashing. You can (if you have
the right model) CLEAR that "Check Engine" completely when (with the
ingition ON but the vehicle not running) turn the ECU adjustment (on some
models) fully clockwise AFTER it has blinked for at least 4 complete series
of the error code it's got. Of course - if the ERROR still exists, then your
Check Engine light will turn on again pretty quickly.  There are "Haynes"
manuals in the parts store (at Pep Boys for sure) that will tell you exactly
what problem you got if you know the right number of 'Blinks'. The Haynes
books usually cost about $13.
