I trying to clean my catalytic converter without removing…

Customer Question
I trying to clean...

I trying to clean my catalytic converter without removing it. I've tried gas treatment, but my check engine light still comes on.

Mechanic's Assistant: Does the light stay on, or does it blink?

The light stays on.

Mechanic's Assistant: What is the model/year of your Toyota?

2001 Toyota rav4.

Mechanic's Assistant: Are you fixing your RAV4 yourself? What have you tried so far?

I've tried gas treatments, and a higher grade of gas. I was hoping to find a gas treatment that would do the trick.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Nothing I can think of, other than a reasonable price, 900 to 1,200 is far beyond my budget.

Sometimes this code can be the result of a poorly running or tuned engine or an exhaust leak. Also, at times the rear O2 sensor can cause the problem.

If you haven't, try Cataclean on the exhaust system, this has mixed results and if it doesn't work, then it's likely going to need a new converter.

Here is a link to the cataclean
