i have both of these in my car and still get my SES light every few days....is the o2 simulator messing with the ecu still? and should i disconnect it? my obd reader says i have the P0138 code for high voltage and the other code i get says N/A on the reader. What should i do? thanks

 

disconnect the battery and connect it back. it resets the ecu

 

You can turn off your rear O2 sensor w/ Ecuflash; read up and you'll no longer need a simulator or O2 fouler.

 

will this allow you to pass emissions if you turn it off? im havin the same problem i need to pass emission my plats expire today and i cant get a new one without passing emission any help would be great!

 

Yes
