I have a 97 Dodge Dakota wish a 5.2L V8. Last week the check engine light came on and it was running a little rough so I took it to Advance and their code reader came up with 2 misfires. I changed the spark plugs and the truck started running a lot better. The check engine light never went off so I went to advance a couple days ago and he resets the computer since it still had the same codes and I had replaced the spark plugs. I've driven maybe 5 miles since then.

Well today I take it to Jiffy Lube to have my truck inspected and it failed due to too many readiness monitors in the not ready state. Catalyst, O2 Sensor, and O2 Sensor Heater are all Not Ready. I was looking online and read that the parts could either be faulty or just maybe hadn't had time to reset yet. Anyone else had similar problems?

"My vehicle was rejected for being "Not Ready", what does that mean? On-Board Diagnostic II systems (OBDII) perform self-tests of their various emissions system components utilizing various monitors while the vehicle is driven. Therefore a vehicle that has received a North Carolina emissions inspection result of "not ready" due to recent maintenance or vehicle's battery replacement or disconnection must be driven to reset monitors to a ready status. These components are referred to as "readiness monitors" and identify whether the vehicle's computer has meet the vehicle manufacturer "enable criteria" conditions to run the required "diagnostic tests". * The following are suggestions that may help get your monitors to a "Ready" status: Drive your vehicle for several days under normal conditions including some highway driving at the speed limit. * Contact your vehicle manufacturer or repair technician and inquire about Recalls, manufacturer applied Extended Warranties, and Technical Service Bulletins (TSBs) regarding the emission control system (research by your VIN). * Make sure all thermostats and fuses are working properly. * If your vehicle has had an after-market radio, CD player or security system installed, make sure that the wiring is not interfering with connection to the vehicle's computer or battery system. * Have a diagnostic analysis performed using an OBDII Generic Scan Tool. * You may be able to obtain a copy of your vehicle's "drive cycle" from your vehicle manufacturer. You may also find information regarding your vehicle's "drive cycle" in the owner's manual. "

from what I understand you need to put about 100 miles on your car before it will all reset for inspection

4/14/2007 1:58:10 PM

like ^ said you need to put some miles on. Not sure if its 100 though.

4/14/2007 2:39:30 PM

maybe its 300

I can't remember...but it was a good amount

4/14/2007 2:56:56 PM

yeah, I saw where it could be anywhere from just a couple miles to 300+. Worse thing is that 300miles = about $60 in my truck. anyone want to go on a short road trip.

And apparently you can get a not ready waiver from the DMV office if it fails twice and you either tried to fix it or put a "reasonable" amount of mileage on it.

"# Not Ready Waivers In order to receive an emission inspection the vehicle's OBD monitors must be in a "ready" state. If a vehicle has too many "not ready" monitors, the vehicle will be rejected from receiving an emission inspection and receive a Not Ready Rejection VIRS. The vehicle must be driven in order to set the OBDII monitors to a "ready" state. Some vehicles become ready very easily while some are more difficult to become "ready". Acceptable limit of not-ready monitors are: 1. 2 - for all 1996-2000 model year vehicles 2. 1 - for all 2001 and newer model year vehicles There are different scenarios when a not-ready waiver can be issued. Please contract your local DMV office for specific information. Below are the general procedures for the not ready waiver. 1. The vehicle is rejected from receiving an emission inspection because it has too many "not ready" monitors, exceeding the acceptable limit. 2. The customer attempts to get the vehicle's monitors to set by performing any of the following steps. 1. Repairs, and/or 2. Normal Driving (daily driving habits, i.e. trips to store, work, activities, road trips, etc), and must be documented by a reasonable mileage change between the first and last VIRS or 3. A manufacturer's drive cycle may be conducted in place of driving the vehicle for several days. The drive cycle performed must be presented to DMV personnel. 3. The vehicle returns for another inspection and again has too many "not ready" monitors, exceeding the acceptable limit. Another Not Ready Rejection VIRS will be issued. At this point a not ready waiver can be issued. 4. Owner takes the two Not Ready Rejection VIRS to the local DMV office along with the manufacturers drive cycle, if one was used. If a Not Ready Waiver can be issued, DMV personnel will make the proper arrangements with the inspection station where vehicle will be inspected. Under the supervision of DMV the inspection station will proceed with the OBD inspection making special allowance to complete the emission inspection. 5. The vehicle must pass the visual tamper and safety inspection portion of the emission inspection before a waiver number can be entered into the analyzer"

disconnect the battery

[Edited on April 14, 2007 at 9:25 PM. Reason : then put some miles on it]

when you disconnect your battery the computer needs to go through approx. 2 cycles before those monitors are no longer in the ready state. Shouldn't be any need to disconnect the battery again since I'm assuming that's what the Advanced Auto guy did to reset your comp. to begin with... simply drive a few more miles (100 should be good, unless you're just doing slow around town driving... as you can see below speed, temp, etc. can all be factors)

Quote :

"The conditions necessary for the monitor to run testing are referred to as the “enabling criteria.” Some monitors require the vehicle to follow a prescribed “drive cycle” routine as part of the enabling criteria. Drive cycles vary among vehicles and for each monitor in any particular vehicle. Some non-continuous monitors require two drive cycles to complete testing due to the need for a cool down and warm up periods in between. For more information on drive cycles, see the discussion below. Depending on the non-continuous monitor, variables such as speed, engine and ambient temperatures, load, fuel level, as well as other conditions must be met for the monitor to perform its test."

the owners manual will have the exact driving conditions you need for all readiness cods to clear, per federal law, i'm not at home so i cant look it up on alldata right now

should be about 200 miles for everything to become ready on your particular truck.

how many miles on the truck? the 5.2/5.9 is pretty notorious for throwing misfire codes after they get some miles on them. predetonation is a problem as well as carbon build up.

^ #8 cylinder, sucks oil right through the breather and into the intake and fouls the plug like hell

4/15/2007 5:00:08 PM

about 142,300. Just put over 300 miles on it with a trip to carolina beach and back.

4/15/2007 5:40:18 PM

i just got the same error on saturday... the system just said I needed to drive the car 100 more miles or so to reset it (it's been weeks since i had the exhaust work done though, so i'm kinda "huh?" about it... but whatever).

4/16/2007 1:25:33 PM

well. all's well that ends well. 300 miles and $60 in gas later and everything passed. It's fucking stupid that it fails just because it hasn't been driven long enough.

4/16/2007 4:28:37 PM

You do realize just WHY you have to drive it a minimum number of miles/drive cycles, don't you?

4/16/2007 4:51:52 PM

did you disconnect the battery?
