Default OBD Check Engine Light Help

My OBD Check Engine Light came on yesterday. The car runs fine and the light is not flashing and it does not display any codes. I read that if you cycle through around 5 starts it may get go off. Does that mean actually driving the car 5 times or just starting and stopping the engine 5 times? Thanks!

If driving it once doesn't reset the light, restart the car a few times without driving.

Last resort is to reset it manually with obd reader.

You can read to the code with any OBD2 reader.
Let us know the code

I’ll go get a reader today. I assume they are universal and I can get it at a local auto store.

Yes they are.
The stores will also read to code for you.

I got a Innova 3100j OBD scanner. No codes came up only this information,
“Emission Related Engine DTCs” it then had 4 blinking FUE CAT 02S & HTR
Anyone know what that means. I’m guessing Fuel, Catalytic Converter, 02 Sensors and no clue HTR Heater?

My guess is a faulty O2 sensor is the culprit, usually is, which in turn is giving other messages. It all goes away once the sensor is replaced.
Has the same on the AV..

Htr is O2 sensor heater. It raises O2 sensor temp before it can measures the hot cat. I think the wires have gone bad or one of the O2 sensors are out.
