Check engine light
Toyota Sienna 2004 had check engine light, got it checked Toyota service people said it is catalyc converter that needs to be changed not O2 sensor as I thought!! While at oil change facility, I just show 2 Oxygen sensor at two ends of Converter and did not see any wire coming out of Converter.
Are they trying to make money by saying converter is needed as I heard people are stealing it for platinum plates inside, and just replace o2 sensor or there is sensor for cat. Converter?
Please help!
