    Probably the CAT ECUs; not the temp sensors.

    If you have verified that all your CAT ECUs are working properly, then my next suspect would be the thermocouples. Are your cats original? How many miles?

    After an oil change I got the light soo there after. I reset my OBDII using my little tester. Good to go.
