Hi
I had the engine warning light on, put a tester on and cleared the error code
The error was:
"Cat might be defect"
I have a 10 month old 200cell Cat so i dont think it's dead
A week later the warning light was on again this time i cleared the error and did this live run

Downstream Oxygen Sensor Voltage - stays at 0mv
Is it dead or could it just be a bad wire/connection?
