How are you able to remove the Service Engine Soon light? The low coolant since a sensor that I need to replace. I have a new coolant recovery tank in the trunk of the SHO right now.

Any inexpensive Bluetooth or Wifi OBD-II adapter you find on Amazon can help you out here.

Get a copy of FORscan and you can pretty much diagnose or clear any code.

I recommend the OBDLink MX+ adapter. Been using them for 6+ years, but most $25 adapter will work.

Clear the code and if its not a persistent issue you should be good for a while.

Use a program like FORscan or Torque Pro to monitor different PIDs to catch early warning signs such as LFT, SFT, Trans Temp, actual Engine Coolant Temp (vs analog dash) and even setup alarms or thresholds.

If you just want to clear the code, undo the positive terminal of the battery and step on the brake pedal 3 or 4 times for a couple seconds each. Reattach battery and start car. Code should be cleared.

I unplugged the battery for about 30 minutes yesterday. The Service Engine Soon light is off. The low coolant light is still on. I made use that the coolant was filled yesterday, but, it didn't help. I will have the new Coolant Reservoir put on soon.

Sounds like the sensor in your current coolant tank is no longer working. That happened one time to me on the way to an alignment shop. Go figure.
But you may want to check the connector. It is on the bottom of the tank and may have come loose.

I already ordered and have a new coolant tank in the trunk of my sedan. Everyone has been trying to finish working on vehicles before year’s end.

Well, crap. Both lights are back on. I'm going to look and see how hard it will be to change that coolant tank.

Stop by your local AutoZone and they will pull the codes for free.

LOL - That's right, you DID mention you worked at a parts store.
So, what is the code now?
