Is this possible? I keep failing inspection even though Lund sent me a new tune to turn on my O2 sensors. Drove like 200 miles and the O2 sensors still show not ready. Is there a way for me to check their readiness on the Ngauge without going to the inspection station and just waiting for them to give me the results ?

You can absolutely check this with the nGauge. Go to IM Monitors under Diagnostics and they should be displayed. They should turn Green when they pass their checks. If they are not illuminated I think it means they are disabled.

Nice...just checked. I assume red would mean not ready?

Well that works. Unfortunately my 02s are red. Wonder if it just takes more time ?

I'll check mine at some point this week. Lund has me running a tune with the O2 sensors on and I have one with them off as well.

You'll have to ask your tuner if theyre disabled or not, nobody else here can tell you that. Each tune is different.

My O2's are red. Just checked today.

I just opened a ticket through Lund's system to have the two tune files I have checked to make sure both are not set to off.

Lund already responded and is going to double check my file. Otherwise, I guess I need to start checking my wiring on my rear O2's to my headers. I'm positive they are connected though.

Not sure what it will take to get them to start reading. I just assumed they were on and I never threw a CEL.
