LOST JEEPS :: View topic - 2006 Liberty CRD CEL, no codes stored

Funny you bring that up about the transmission not engaging. This one is doing that as well. After it sits for a day or so, every once in a while, it acts like its in neutral when you put it in drive or reverse.

I have been looking at the GDE tune with the flash programmer for $300. Does the include the flash or is it just the module to do the flash, and you have to pay an additional 450 to get the flash? Thats a lot of flashes in one sentance... I like the idea of the programming tool, just in case the pcm gets FUBAR at any point, you can just hook up and be done with it. Does it really do everything they advertise? It sounds like a win in many circumstances for me, as we live in the flats of Denver but like to drive in the hills.

Thanks for all your ideas fellas. Going to try the tranny filter this week, then definately going to go for the tune, if not just for grins.

Does anyone know the fluid capacity for the 15 bolt tranny off the top of their head? Nary a note in the owners manual!

There is a defective series of coolers? Thats new info to me. Is there a span of serial numbers or a way to tell if its a shoddy one?

The filter has the check valve built into it im assuming?

Ok, went to have the emissions test run and we were turned away because the CEL is on. Hooked up to an obd2 and alas, no code stored. Tried to reset but it wouldnt because there is no code. Took it to the dealer and they hooked up to it as well, no code. They however, were able to reset the light. To our dismay, it came right back on with no code stored. Any ideas out there? No emissions, no tags. We are tired of paying for tickets for this as we have to drive it to get to work...

Try a different dealer. some of the aftermarket readers won't find everything - but that part of the rights to be a dealership - you have to have the up-to-date computer & software to read codes - including stored ones. also find a dealership that can do inspections - if they say nothing wrong - they certify it. oh yeah - Welcome to LOST

What is the odometer reading? What repairs have been performed? My cheap Harbor Freight code reader picked up a P0401 code which the scanners at two auto parts stores didn't catch. The code would only show briefly after the engine was stopped and the ignition was switched back on. If your EGR system hasn't been serviced, the EGR valve and the Flow Control Valve are two likely suspects. GDE Tune will eliminate the CEL. Faulty transmission filters also caused CELs for me, but I could read the codes. The symptom was that the transmission wouldn't engage immediately after setting overnight. Leaking charge air hoses are known to throw codes. Wrapping the hoses with self-fusing silicone tape is a temporary fix. Seems like the diagnosis should be covered under the emissions warranty. The vehicle won't pass emissions inspection because of a malfunction which can't be diagnosed by the mandated diagnostic system.

No repairs done as of yet. Waiting for a decent day off to climb under the hood to clean the egr. Seems every day I manage to get off, old man winter wants to come by and piss me off. Shes got 67,000 miles on her. The noob had a few things I am going to try as well, but it just blows my mind that 3 different scanners pull no codes. I may wind up picking up a harbor freight obd scanner just for grins. Funny you bring that up about the transmission not engaging. This one is doing that as well. After it sits for a day or so, every once in a while, it acts like its in neutral when you put it in drive or reverse.

Transmission filters are doing that, sounds like it's time to service your transmission.

Cleaning the EGR valve is a major pain- not an afternoon job. You might try cleaning just the elbow from the FCV to the inlet manifold. That's more accessible. You might want to compare the costs for a new EGR valve and/or a flow control valve and all the labor required for their replacement against the cost of a GDE tune. If you service the transmission, the CEL will remain on for something like 40 cold start cycles after the repair. My Harbor Freight scanner could not clear the codes. The dealer would have cleared the codes for about $100.

The CEL for the EGR code is now not lit, though.

I got an Eco tune about a year ago. It performs exactly the way they claim. FWIW, I had a P0299 code when I bought the CRD. Got a deal because the dealer couldn't figure it out. They put new CAC hoses on it; I cleaned the MAP sensor. Keith suggested it might be the EGR. No light after the tune. For me, it was worth every penny. For towing, I will probably get the full torque tune along with TCM re-program. How long have you had your CRD? Commonly inherited problems generally involve a non-working thermostat and a non-functioning fan clutch. good luck

Bought her brand new in 06. Shes been a great ride for every single mile. There is no better place to own a jeep than in colorado.. Except when you cant pass the emissions! I think I will replace the tranny filter to start, then take my penny jar and see if I can squeeze enough out of it for the GDE tune. Both sound very promising. The transmission issue that was brought up happens often enough that its worth looking into, and the bene's of the tune sound even better, though it is nice to smoke a tailgater every so often...

The ECO Tune is worth every penny. My Libby runs like a "bat outa hell." Never had a CEL, but for a blown CAC hose. For what it's worth.

Thanks for all your ideas fellas. Going to try the tranny filter this week, then definately going to go for the tune, if not just for grins. Does anyone know the fluid capacity for the 15 bolt tranny off the top of their head? Nary a note in the owners manual!

Make sure that the cooler filter is not one of the defective series. Don't over-torque the pan bolts -no air wrench. If the filter changes clear the DTC, it will take 40 cycles from cold to warm engine before the CEL goes out- unless you have a scanner that can reset the tranny codes. EDIT: What actually happened with the transmission filter DTCs was that the CEL went off after filter replacement, but the DTCs didn't clear for 40 cycles.

The factory filter for the cooler, which is installed in the transmission, had a defective check valve. The coolers were OK. Some of these defective filters seem to have made their way into the supply chain.

My VIN was not in the recall group, however the dealer's proposal to correct the transmission DTCs was to do exactly the same work as required by the recall, except at my expense. I changed the filters and fluid myself and the DTCs self-cleared eventually after 40 start cycles.

Sweet. I will do that as well while I am rootin' around in there. I've gotta get this friggin light off. Then I can move on to fixing the rear window regulator. The glass is being held up with sticky hooks. Looks a lot better than tape on the outside, thats for sure. Thanks again for your help, ya'll.
