Most likely it's tire pressure.
Under the dash board, exactly in the middel. You need to remove the dash board compleately to get to it.
There are several warning lights on the dash board of a 1993 Toyota Camry. There is a hot water warning, a low voltage warning, a low fuel warning, and several others.
Tire pressurs is low
The ORVR valve in a Toyota Camry is an on-board refueling vapor recovery valve. This valve is located in the upper portion of the fuel tank.
There is a little button on the transmission shift stick, from the driver's side. Just press it, and you will see light in your dash board... And you will get what you want.
there will be a small button below the gear shift stick.... on the stick itself.. just click that button.....
Hold down Shift and press 1 on the number row.
If i remember correctly that code is a result of either running the vehicle with gas cap off or not fully tightened at least 3 clicks.
It's probably the tire pressure warning. You may have a low tire. I think you have to get the computer reset even after you correct the tire pressure problem.
Right behind dash board
Check fuses for the air bag system. If they are ok. You have no choice but bring at the Toyota dealer place. There is not much what you can do when you have some problems with the safety system.
It is the passenger eject button.
