I got a "not ready" at the emissions test. It has been over a month since the battery has been out. It should have completed a drive cycle by now. I can't find the exact drive cycle in the OM, repair manuals or online. Does anyone know it? 98 G. Caravan 3.3 fwd

 

It can take 500 miles for the emissions to reset. If you only take short trips, it may not get up to operating temperature for the sensors to ensure proper operation.

 

It has been well over 500 miles now. Their has been mountain driving, flat land and lots of city driving. I did read something about the temp needing to be around 170, the van usually stays right in the middle. In the article they had to put the van on a lift, run it up to 55 mph for 5 min and let coast to an idle. [/align]

 

it will all depend on what system has not run the test yet. If u cant get that info from a shop that u want to pay the money for just unplug your batt again and drive for a week Your 98 3.3 should have 4 tests egr,02 heat,cat and evap

 

I put a obd reader on it, it told me cat not ready, egr not and one of the o2s.[/align]

 

ok so that means that none of the tests have run. Yor adptive numerator more then likely has not been learned. Use the obd reader and clear the codes and odb info drive 10 miles in traffiic then drive for a few days check with the reader again and see what has been learned. U only need 3 of 4 to pass your emissions test

 

It is telling me their are no active codes. I have tried telling it to clear but their is nothing to clear. I guess I could unhook battery and start over.[/align]

 

Well, I did the battery, erased the codes, and took it for a 30+ mile drive. I tried to do the 55mph down to a idle a few times. Irescanned and only get one not ready,the heat 02. That one was ready last time, but I will try to take it through emissions once more.[/align]

 

I am in the same boat. i have the C and the E letters flashing on my code reader. I did 200 k today and those 2 are still flashing.

 

this is all i have found so far. 1 drive cycle for odb2 reader for chrysler.
