Hello all, Dodge forum newbie here, I also use forums for my Harley and are very informative.
Check engine light issue,- took to get inspected and check engine light cam on, obviously would not test with the light on. Found information on how to clear codes from the OBD, cleared and came back,took to Auto Zone to hook up to their computer for diagnostic. Replaced oxygen sensor at their recommendation. Hooked up cleared codes again, took back down for the re-inspect, 3 of the many codes show "not ready". Tech suggested I drive for 50-60 miles for the OBD to relearn the codes. Sunday toured 3/4 of my county driving 75 miles, took back for the re-inspection, and the codes still showed "not ready". Can anyone tell me how long this takes to ready these codes? I drove another 40 miles yesterday making 110 miles since the codes were cleared, any information woudl be appreciated.[sm=WTFsgign.gif]

 

The computer will reconize any codes that appair immediately. Codes only come up if there is something that is wrong. So when I hear the Not Ready. To me it sounds like the scanner is not reconizing the the truck computer correctly. So what I dont understand is right now are you getting a check engine light. You could also post under the 1st gen dakota.You will get more responses.

 

Check engine light is not on now. The issue is when the inspector hooks up to the computer, the O2 sensor codes and the AC clutch code show "Not ready". Apparently a "not ready code" is the same thing as a "fail" on the state inspection equipment.

 

Oh okay. Those are tests. It just test those systemsout. The cheaper scanners do not test those systems out. They only read codes. The $2,000 models do the test. Everything is okay if you dont have a check engine light on.
