Question about 1995 Toyota Camry
A malfunction indicator lamp (MIL), commonly referred
to as the "Check Engine Light" is an indicator of malfunction of the
computerized engine management system. It is found on the instrument
console of most automobiles. When illuminated, it is typically either an
amber or red color. On vehicles equipped with OBD-II,
the light has two stages: steady (indicating a minor fault such as a
loose gas cap or failing oxygen
sensor) and flashing (indicating a severe fault, that will
eventually destroy the catalytic converter, such as a misfire). When the
MIL is lit, the engine
control unit stores a fault code related to the malfunction, which
can be retrieved with a scan
tool and used for further diagnosis. The malfunction indicator lamp
is usually labeled with the text check engine, service engine
soon, check engine soon, or a picture of an engine.
The MIL appeared in the early 80s along with computerized engine controls. Even the earliest systems, such as GM's CCC (Computer Command Carburetor) system had self diagnosis functionality. When the computer detected a fault, it illuminated the MIL. Up until OBDII, on most cars the MIL could output codes, when two pins on the ALDL are jumped, the light would flash the codes, for instance (blink) (pause) (blink) (blink) for code 12. Some manufacturers retained this feature even after OBDII, such as Honda.
Hope this help (remember comment and rated this). Good luck.

engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.
