2005 WK 5.7 I/M readiness sensors showing N/A

I just failed a smog check due to lack of OBD-II readiness. Usual solution is drive more, complete the cycle, etc. I dont think thats the issue. The failure struck me as odd, so I pulled out my code reader and looked up the I/M readiness stats. It shows as readiness OK, but almost all the sensors are reading N/A, as if they dont exist, which I know isn't right. At least if it said BAD or INC I could figure out what to replace or drive more. I attached images, but they read as below. Can anyone tell me what I *should* be seeing?
MIL Status OFF
Misfire Monitor N/A
Fuel System Mon. N/A
Comp. Component OK
Catalyst Mon N/A
Htd. Catalyst N/A
Evap. System Mon N/A
Sec Air System N/A
A/C Refrig Mon N/A
Oxygen Sens Mon N/A
Oxygen Sens Htr N/A
EGR System N/A

Is there no one who could plug their code reader in and see what sensors are present? I'd really appreciate it. I can't seem to find a reference for this.

Re: 2005 WK 5.7 I/M readiness sensors showing N/A

I have an Autel DS708 and an AutoXray Code Scout 2500 and used it (Code Scout) to check my 06 Hemi Overland. There are 8 Emissions Readiness Monitors and it reads, "8 of 8 readiness monitors are complete." They just show a check mark beside each one that indicates, "complete". Haven't hooked up the Autel to check what it says. Other code readers may use different terminology though. Hope this helps.

Here are the monitors:
--Misfire
--Fuel System
--Comp, Components
--Catalyst
--Evaporative System
--O2 Sensors
--O2 Heaters
--EGR

Re: 2005 WK 5.7 I/M readiness sensors showing N/A

Thanks guys. Glad both your results sync up. Not sure why mine shows all those sensors as not applicable. Way too many to have all failed on their own. Hopefully my ECU isn't toast. I'll probably try another scan tool for sanity's sake before I go crazy messing with the truck. Thanks again, all.

1000x Internet Points to each of you!
