CEL with no Codes?
#11
1998-2002 (maybe more) Dodge trucks and Jeeps, put transmission in neutral, parking brake on, then do the acc-run key sequence 3 times ending with RUN.
There was an obvious change in the way codes were retrieved from ’98-’00, but people are able to do it without a scan tool. Some people on different forums have reported having to do the key on-off cycle 5 to 10 times others the inst test method also shows codes. Maybe Chrylser was testing out various methods for those years before settling on a single method.
It can’t hurt to try.

Well then how about this method. Quoted from Allpar.com

Yes the TB is separate from the intake manifold. It is very easy to remove, I would put in a new gasket while you're at it.

Well I Held the trip reset down and did it that way, It did check through all the lights and checked each gauge but that is where it stoped it did flash any codes on the odometer at all like it said it would. Ohh well Just going to do a tune up, clean the IAC and TB and go from there to see if it doesn't come up again.

See the option was not installed into the PCM software until 2000 in the Durangos, and I also believe the Dakota. Now in other Chrysler products they have been messing around with it for years, but it was a "Blink" that the engine light would flash. It would flash in 4 series giving the code.
Basically if there was a code in the system stored and you did the key dance it would blink only the code. For instance it would blink 1 time then hold about 3-4 seconds, them blink 2 times then hold for 3-4 seconds, then blink 3 times and hold for 3-4 seconds, then blink 4 times and hold again if the code was in the thousands. In this series as I have described you would get a 1234 when you put it all together. This code would mean that you were dealing with a P1234 code and you would fix it.
Now when they graduated to OBD-II most of this was changed and integrated software was then installed into the compliant PCM. Again in 2000+ years. This set the new wave of just popping up the code, instead of counting blinks and hoping you got it right. It was a much better system. There was medium cross over years nothing was installed like in the 1998-1999 Durango and Dakota.
The reason you are getting mixed reviews is because people state that it will work, but fail to describe exactly what they have and the people that are giving the information in the first place don't quite know what they are talking about. Here is the correct way to get the codes on the 2000+ Durango's:
2000 and newer Durangos have a built-in system that can display check engine light (CEL) codes without the use of a scanner. 1999 and earlier Durangos must be read with a OBD-ll scanner. Your local auto parts store can get the codes for you either way and will usually do this for free.
2000 and newer directions:
Turn the key to ON (not start), OFF, ON, OFF, ON and leave it there. If you look in the odometer window the codes will flash any code(s) with a small delay between each result. Each code should be in a P#### format, and will say PDONE when completed - turn your key to OFF and remove. Use the OBD code list to determine what problem the computer detected.
To reset your engine codes:
Remove the negative terminal of your battery (10mm wrench).
Turn your ignition key to START and hold it there for about 15 seconds.
Turn your ignition key to OFF and remove it.
Connect the negative terminal of your battery.
Start but do not hit the throttle. Idle for about 10/15 seconds then turn off.
Restart the truck and drive as usual. It will take at least 12 starts and 48 miles to fully retune the computer. Hard Codes leave a shaddow for 40 full cold starts.

Ok, thanks Hydra I'll buy that the option in the software was removed for '98-'99 and your reasoning for the misleading info I've been getting. But OBD II was mandated on all cars and light trucks sold in the U.S. in 1996 and the key on/off method absolutely worked on my old '97 Dak 3.9 5 speed.

Good stuff here and confirms that '98 and '99 dodges need a code reader but '97s didn't.
