Re: P0420/P0430 - Can I Get A Witness?
FinnL, have you had good luck with the URD simulator?
I'm adding my last comment to this post since I'm fed up with this greed non-sense.
Just as an FYI, the ECU's are just plain to sensitive for the Cat efficiency fail codes P0420 and P0430. You can have as little as a 5% restriction with the cat working fine and throw these codes.
I am also plagued with these cat codes in a Sienna and just sick and tired of this problem.
The other issue is the scam sucking Toyota blood sucking leaches disabling the VSC and traction control. That pisses me off the most since it's a safety device that Toyota is using as bait to scam you back to them to sink thousands of dollars in repairs. Everyone needs to place a safety complaint with the NHTSA and ask that a recall is done. Most states don't require emissions testing so all of us shouldn't be held hostage with the 4 lights glaring in our face and driving an unsafe vehicle for greed. Since the consumer protection is such a joke my only alternative is to try the O2 simulator method. Has anyone had any luck with the URD simulators?
