Many auto parts stores will read the codes for free.

Most likely reasons:

O2 sensor(s)
EGR value and/or charcoal canister
gas cap problem

You can still run the car, but you will have to get it fixed prior to next
emissions inspection (where applicable). Also, in some cases, especially if
the engine is not quite as smooth as previously, it "could" be doing some
damage to the engine if you drive it that way for a long time.

From Autozone's free repair guide.
1996+ use Autozone's OBD-II reader,
pre-1996 see:

Driveability & Emissions Controls
--> Trouble Codes
--> Reading codes

1982-95 MODELS
All models except the 1MZ-FE engine is equipped with OBD I till 1995.

1. Make sure the battery voltage is at least 11 volts.
2. Make sure the throttle valve is fully closed.
3. Place the gear shift lever in Neutral. Turn all accessories off.
4. The engine should be at normal operating temperature.
5. Using a jumper wire, connect terminals TE1 and E1 of the Data
Link Connector 1 (DLC1).
6. Turn the ignition switch ON, but do not start the engine. Read
the diagnostic code by the counting the number of flashes of the
malfunction indicator lamp.
7. Codes will flash in numerical order. If no faults are stored,
the lamp flashes continuously every 1/2 second. This is sometimes
called the Normal or System Clear signal.
8. After the diagnosis check, turn the ignition OFF and remove the
jumper wire.
9. Compare the codes found to the applicable diagnostic code chart.
If necessary, refer to the individual component tests in this section.
If the component tests are OK, test the wire harness and connectors
for shorts, opens and poor connections.
