Help, today i just got a CEL, since i had a CarChip in my car at the time i just unplugged it and hooked it to my computer. so the code comes out to be:
Description: Catalyst System Efficiency Below Threshold (Bank 1)
can anyone tell me what this means?
* gas leakage on exhaust system
* Open or short in heated oxygen sensor circuit
* Heated oxygen sensor
* Three-way catalytic converter (whatever that is??)
