Hi: I am having the same problem with "3 sensors not ready" (Cat, O2, o2 heater) while trying to get my car inspected, I was wondering which software did you use to access the OBD sensor setting as shown in this posting by you? My car was tuned last year by Melon, and I think he used the Tephra mod, because I have the flashing CEL for knock indication after the tune. Thank you.

 

Can you look at this ROM to see if my ODB sensors for Cat/O2/o2 heater are off? Thanks

=05blue8;8773318]Who did your flash? You can easily set everything to "ready" in the tune depending on what is or is not enabled in your ECU. Contact a tuner on the site or wait for one to chime in. I'm sure for a small fee one would take the time to update your ROM and set all the stuff to ready. What do you have emissions wise on your car? What isn't reading ready? o2? cat? egr? e-mail me your rom file - mattheww1978@hotmail.com and I'll take a quick look, it's very easy to set up...[/QUOTE]

 

Rather than start a new post, I have the same situation as the OP.

I have a downpipe -> cutout -> stock catback

No CELs are on

All sensors are in place although I don't know what's turned on or off.

The only NOT READY lights that come on according to OBD system check is catalytic converter efficiency and EGR (turned off since EGR is removed). 02 and Heated 02 are both READY. I have an 02 simulator on the car. What would cause the cat efficiency to be NOT READY?

 

If the rear 02 sensor is turned off would that cause cat efficiency to be not ready? Is there a manual sequence instead of going in ECUflash that could turn it back on?
