Tuning out 02 sensors and PA State Inspection

Post by Gossamer »

I purchased the Diablo Predator for my 06 Dodge Charger Daytona w/LTH's, to remove a trouble code (p2098). I turned off the rear O2 sensors and that fixed the problem with the CEL no problem. Yet, when I go to get the car inspected, the shops OBDII reader say the car has go gone through a full cycle and the catalytc converters and the rear 02 sensors are not ready. I drove the car over 500 miles before taken it back to be inspected again, but the OBDII reader still say the cats and 02's are not ready.

My question is... will they ever be ready?

I need some feedback asap, my charger is 2 months past due on my inspection. Will turning the rear 02's back on and turning off the 02 heaters remedy the problem? Do I just need to drive it more? Do I need a priest to come and pray over my LTH's and 02's? At this point I will do about anything (short of taken off the header).

They'll never be ready, because they're turned off. They're just there to plug the holes at this point, not doing anything. You gotta turn them back on for the inspection and pray that they don't throw a code.

I have turned them back, but the code is thrown everytime I put them back. I have tried to stop the problem at the source, by calling SLP (they are SLP LTH's btw), but they weren't any help and told me to contact the kind people at Diablo.

Not sure what to say here.
If you liver in an emissions state, you really should not remove the cats, as it is bound to cause some issues down the road.
You may need to reinstall the stock cats to overcome this issue.

That's the thing, I have high flow cats, guess that's the same not having any at all. I thought putting the stock ones back on would throw a different code. If the cats are the problem should I call SLP back up and bother them some more? I will try reinstalling the stock cats if that will fix the problem, but I really thought the hight flow cats should work.

You might have luck with O2 bung extensions...Moves the rear 02 sensors out of direct stream.

I am not to sure of the PA Insp regulations, but if they are similar to NY then you are allowed to have 1 system not ready, like stated above try the extensions you may have to install 2 sets of them. The best way to make the O2's go ready is when they are cold, try a drive cycle first thing in the AM, and then have the monitors check before the Insp. It may take a try or two but you should be abel to get it. Good Luck.

GOSSAMER MAKE SURE THAT WHEN YOU INSTALL THE EXTENSIONS YOU TURN THE O2'S BACK ON WITH THE HEATERS.

there is nothing in the PCM that will allow for a 'fix', other than a high flow cat that the PCM believes is 'there'...

To bad the great guys here in Diablo can't come up with an adjustment for this issue. There are alot of people over alot of different forumZ, having issues, Only way anyone gets around this is, on run the car till everything heats up good, then clear the fault right before inspection. Your Hi-flow cats may or may not throw a code right off the bat, heck may even go days before it throws a code, but it eventually will. I have no leaks in my exhasut system, I have Hi-flow cats, and Longtubes also. it's just one of those things you will have to deal with unless, as I stated above, Diablo can come up with a programming fix for this or no one uses LT's and hi-flow cats.

I'm not really sure what their programming can do or even if they update their sofware for more uses out of it. I know the California guys would love a fix for this. Diablo would probably sell alot more units if they could solve this problem
07 CHARGER R/T: 6.1L Cam, springs, & rods, Dynatech headers W/ Hi-Flow Cats, AFE CAI, Catch Can, Flowmaster Catback, Jet 180 T-Stat, Hotchkis Sways. All installed by myself, I paid no one for installation of any mods.
Future mod wishlist: Pedders suspension, heads, bigger cam, LC-1, & Nitrous.

Do you have the rear o2s installed and turned off? If so, have you tried non foulers for the rear o2s?

you CANNOT do that, when you erase codes, you reset ALL of the emissions monitors
99% sure that 2098/96 code is not tune related, its an exhaust leak
