If it's an OBD1 car (typically before 1996) you can manually access
the codes and find out what they are by watching the "check engine"
light blink. If it's an OBD2 car, then no...you have to have a code
reader.
The good news is that many auto parts stores will read the codes for you
for free (autozone). Just be careful listening to their diagnosis.
Good luck.

I find this procedure, test it for retrieving trouble
codes...
RETRIEVING CODES
1 . Before
retrieving codes, verify CHECK ENGINE light comes on with ignition on
and engine off. The CHECK ENGINE light should go off when engine is
started. If light remains on, system has detected a malfunction or
abnormality.
2 . Ensure battery voltage is greater than
11 volts and charging system is okay. Engine should be at normal
operating temperature.
3 . Apply parking brake. Shift transaxle
to Neutral (M/T) or Park (A/T). Turn A/C and all accessories off. Close
throttle valve.
4 . Turn ignition on with engine off. Install
jumper wire between terminals TE1 (or T) and E1 in engine check
connector. (Location of DLC might differ from diagram as it is only for
illustration purposes).
5 . Count number of flashes from CHECK ENGINE light. If system is
operating properly (with no codes), CHECK ENGINE light will flash
continuously and evenly.
NOTE: If CHECK ENGINE light will not flash diagnostic codes, see
appropriate DIAGNOSTIC CIRCUIT CHECK.
6 . If code exists, digits
of each code will flash at 1/2 - second intervals, with a 1 1/2 - second
pause between first and second digits.
7 . If more than one code
is stored, a 2 1/2 - second pause will occur before next code is
flashed. Once all codes are displayed, a 4 1/2 - second pause will occur
then code(s) will be repeated.
8 . Codes are displayed
from the smallest to largest code. After codes are retrieved, remove
jumper wire to exit diagnostic mode.
Ignition coils and ignitors
do fail now and then resulting in no sparks. Perform a spark test to
confirm if sparks are available and bright blue and not dull orange.
