I am having problems with my SES light coming on. The computer is saying bank 1 is too rich. I took it to the shop and they replaced both oxygen sensors before the converter. The light went away for a couple of days. It came back on so I took it back to the shop and now they say the oxygen sensor after the converter is bad. My cats are gutted. So I was told I should buy some O2 simulators to cheat the computer and the light would then stay off. I was wondering if anybody else uses or heard of these simulators and do they work. Thanks for the help.

 

O2 simms only work for OBD2 and post cat only. Can't use it for the pre cat O2 sensors. They adjust the fuel trim.

 

I used them and they worked fine for me. The other option is to not buy them and just have them programed out in the pcm/ecu/computer whatever you want to call it

 

The guy I bought the car from had that code into the computer. But somehow it is not reading it now. How does that happen?

 

It's cheaper to have them programmed out.
