Hi Sumith, the EXH TEMP lamp is to worn that the Catalytic Converter is overheating.

If you car no longer has the converter attached to the exhaust piping, then the signal is bogus/invalid.

Hi DD

I remember it has Catalyst converter down under the exhaust pipe near to mainfold down area, earlier also i had that working , since i have noticed it is on while i put ignition on and go off sometime as soon as i start the engine and sometimes after few minutes of running the engine,but now it doesn't die at all that is what i am worrying about now

thanks

When the light is on, feel the floor where it bulges up next to the seat. If it feels extremely hot, do not drive the car.

If the engine misfires, it causes the catalyst to overheat. Have your mechanic fix the engine.

If the floor is just warm, then the light may be malfunctioning. If the light comes on immediately after starting the engine after sitting overnight, then the sensor has malfunctioned.

or if not required by law- remove the cat convertor completely and disconnect the light.
