Car stalled and statrted overheating. Checked my oil and it was low. 01 gs 300

 

If your CEL is on there's a code stored...have it scanned and post it here.

 

I am having the same problem. I have a 2003 GS300 with 160k miles. I washed and waxed it Sunday and took it for a spin after and within two miles after leaving my house my Check Engine light came on alone with VSC and VSC off. I went yesterday to Advanced and got them to pull codes until I could get it to my normal mechanic and it showed the following codes:
C0246
C0256
C1223
C1201
P0430
I called my mechanic this morning to see if I could run it by to him this afternoon and see what he thought about the codes. He said that more than likely it was all a result of the P0430 CAT System Efficiency Below Threshold Bank2. Said it could be the CAT gone bad or maybe just an O2 Sensor.
Has anyone experienced this or have any input. It would be greatly appreciated!
