OK, My 09 R/T is getting its first emissions testing done. I just relocated to a part of northern Va that requires emissions testing. The test is now due. I took it the other day and the inspector said it rejected because it comes up not ready. He does the regular inspection for me and knows the car isn't driven but around 1000 miles a year. I also had to replace the battery a couple of months ago as the original finally died. He had me leave and go drive it for a half hour and bring it back and it failed again. Same code. He said to take it on a long drive over the wknd and we can try again. Little does he know, shortly after buying it I took it to Arrington and had a cam installed, and the computer was re-tuned. I also have no cats, but figured I would try anyway. I still have the original catted mid pipes which I can re-install which I'm sure I will have to. Could the lack of the cats be causing the O2 sensors not to read? or could they be turned off in the tune which is causing this? Any one know of someone that will get this passed? HE HE :D I am attaching my report.

There are no CEL's, I figured I may have to reinstall the cats, but I'm thinking the tune included turning off the sensors possibly to avoid a CEL. This was done 8 or 9 yrs ago now and I am 5 hrs away from Arrington now and Thats if they're still in business. I think they were bought out years ago and that facility closed. American Hi performance is close by, I can pay them a visit and see whats next. The only mods I have are the cam and no cats and a tune, Hopefully I can avoid a cam change. I guess I will reinstall the cats first and see if this affects it.

You need to drive south of Culpeper Virginia to get the car inspected. Geesh,
NOVA is just 'maryland-lite',

Go to Danville or South Boston , Staunton and further south on I-81.
May save from re-installing parts.

Problem here is the car is now registered in the "city of Alexandria". Regardless of where its inspected, an emissions inspection is required for this area.

I was an inspector for emissions. It doesnt matter what ones are not "done". The secondary o2's are for the cats,not the engine. Thats their only job, check cat efficiency. Drive cycle should read the upstream and still make the switch to "ready". The ecu must monitor the upstream ones to make the engine run correctly. Try the drive cycle first. Just remember engine needs to be cold. Usually takes an 8 hr cold soak then a proper drive cycle.
When I went for the first test, the engine was cold, hadn't been driven for a week. I took it to the interstate and got it warm, even running the AC to help heat up, but as soon as I got it there,he hooked it right up and within a few mins he said its not ready, go and drive it some more. He even asked if I jumped it to get it there and I said no, it starts and drives every time, He asked if the battery had been dead or even new, there would be no info stored and it would have to get some run time on it. I went out and drove it 60 miles on the interstate today, hoping it will maybe do something for it?

O2 Sensor Monitor Drive Trace

Pre-Conditioning Requirements:

- MIL must be off.

Driving Procedure:

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Drive with a steady vehicle speed above 25 mph for 2 minutes.

3) Stop and idle for 30 seconds.

4) Smoothly accelerate to a speed between 30 and 40 mph.

5) Repeat steps 3 & 4 five (5) times.

G. O2 Sensor Heater Monitor Drive Trace

Pre-Conditioning Requirements:

- MIL must be off.

Driving Procedure:

1) Idle vehicle for five minutes (to reach closed loop operation).

2) Shut engine off and leave vehicle off for ten minutes.

If readiness status of all monitors do not switch to “complete,” ensure preconditions are met, turn the ignition switch OFF, then repeat the drive cycle. Completing the Dodge Charger drive cycle above should set the emission monitors required to pass the smog check.
WOW....what a PITA! ok, thats gonna be pretty difficult to try to perform here where we have stop signs and traffic lights every other block. So let me ask this....I drove it today on the interstate for some time then in some stop and go traffic. Thats not enough for it to read or prepare? For doing this procedure, I have to go thru a few stop signs and traffic lights before getting onto any road where i can drive above 25 mph. I assume hitting the brakes will kill it right there.

Guaranteed your rear o2's are turned off in the tune and as stated you can drive it until the wheels come off but it aint going to help. You need a new tune with those monitors turned on AND install some cats.
Yep, I'm thinking this is whats gonna have to happen. I still have the original mid pipes, they are basically brand new still LOL, I will bolt those back on and make an appt with a hi-perf shop thats minutes away. They have a dyno and can re-tune it.

I wouldn’t go to this trouble that often, put it to where it passes and be done.
Thats whats going to happen. I bought the car new, 11 yrs ago and where i lived there was no emissions inspections so I went all the way, plus I raced it, so I had no worries. I havent raced it for 7 or 8 yrs now and relocated recently to an area that requires emissions. I figured eventually they would send me a notice and they did............I don't drive it that much now so I guess the cats go on and a new tune. Hopefully they can make it work and with the cam thats in there and tune it to pass.

Yep! Or get high flow cats.
The factory cats flow pretty good from what I understand, they are massive but breathe well. Not like a lot of those small aftermarket bullet style cats.
