1999 Camry DTC P1133

1999 Toyota Camry 2.2L 4Cyl. Auto Trans, 65k miles. I am getting a DTC Code 1133. Variable SwrlCntrl Sol. Valve Bank 2. I have 4 questions:

1. What is a Variable SwrlCntrl Sol. Valve?

2. What does it do?

3. Where is it?

4. How can I have a Bank 2 on an inline 4 Cyl?

I would be grateful for any help understanding this, Thank You.

And yes I lloked in the owners manual… nothing… (lol)

P1133=Air/fuel or O2 Sensor Response (California Emissions)


Thanks Testor, I looked in a toyota service manual and found the A/F thing. Now I need to find out how to check with just and old digital volt/ohm meter. But just for my own education, I would still like to know what that Swrl Cntrl Sol Valve is, I can’t find that in the manual just too many pages to look through. And the Bank 2 on an inline 4 still confuses me.

Well, I reset the CEL and so far nothing for a couple days, the TSB say something about “under certain condition” Maybe I will get lucky and not get those “conditions” for a while. Thanks for the response.
