Help! P3190 & Limp Mode after Air filter check & oil chg

2010 died (Limp Mode) in the middle of the intersection last night, Check Hybrid Sysrem, triangle of death, CEL, ABS, many other lights on! Had to push it to a safe spot and had it towed.

P3190 is the only obdii code. is low engine power right? I had removed the air box to check the air filter yesterday afternoon Just before this happened (slightly dirty so I ordered a new one). I put it back on tightly I thought, but is it possible I knocked something loose or debris fell into the manifold? MAF?

Had it towed to the nearby dealer because I was about to take it in next week for the J0V Hybrid System Software Update Recall anyway (I also have a letter from Toyota regarding possible faulty brake vacuum pump, but it’s not technically a recall and I think unrelated to this). However they’re closed tomorrow (sun) so I’m gonna go over and see if I can remedy p3190 myself because I know I’m looking at them gouging me for $500 just to diagnose it.

Car has 182k miles but the hybrid battery is still under warranty as it was replaced by Toyota at 112k miles under a different owner. Battery fan was getting dust into battery.

Car was running awesome just this afternoon I drove it 40 miles at 60mpg. 50-55mpg per tank, had a head gasket job done 9k ago, oil just changed 300 miles ago.

Anyone have experience with this? I’m hoping a simple remedy, otherwise this could be the end.

 

Over half a tank. 0 miles (0 feet in fact). Regular obdii scanner. Little orange one paid $50. Attached image.

 

J0V recall covers inverter repair or replacement, so I’m hoping all of this will be covered, I’ve never had any such issues with this car and got the recall remedy letter a few weeks ago but haven’t had time to take it in. Kicking myself now but hoping J0V covers it anyway.

 

I didn’t inspect MAF or every hoses position/condition but I will go look today. Very possible that I was careless opening air box top when inspecting the filter. Very possible. And I can only hope a loose hose or MAF is the cause. However I’ve heard that trying over and over to start it in limp mode can damage the hybrid battery. I think it’s down to one bar (if system is working accurately). Never seen it below two bars.

The car is on the dealers lot. While it’s there though, No harm in letting them diagnose everything while fixing the software and inverter, right? $$$$?

Thanks. I had "erased" the p3190 a couple of times, tried starting, it and 'ran' for about 10 seconds, then Check Hybrid System and p3190 again. I hesitate to do that too many times. Are you saying that when the HV battery is depleted entirely, it won't 'run' at all? Deathly afraid of having to re-charge.

 

No worries, same code came back

 

Thanks for the input

 

UPDATE: 1) i am an idiot 2) i am a dumas and C) I figured out why it was giving p3190 and remedied it, I believe. You'd think I'd have noticed that I COMPLETELY pulled off the air intake hose attaching to the throttle body (i think that's the name -- see photo) when checking the engine air filter. I slid it back on (is there a clamp for this? it seems it's just held on by gravity which is what I recall my other Toyota/Lexus intake hoses doing), crossed my fingers, and started. I didn't even clear the code, and the ICE kicked in immediately and stayed on, even though the dash showed the same alerts (see photo). HV charged from 1 to 4 bars, and then ICE stopped as is normal. P3190 was no longer listed as an active DTC, rather a Pending. So, I'm hoping this is it. I could have driven it away, but I have to get the J0V software recall done to pass Smog test anyway, so may as well do it now.

I do have a question about one smaller hose and its clamp (see photo)... sorry I don't know its name. In the photo, is that metal clamp supposed to fit around the outer rubber sleeve above it? Because I tried and it wouldn't stretch large enough. It only fit around the main hose where it joins the air intake assy. I assume this is where it goes, but I don't know the purpose of the rubber sleeve above it? It just kind of sits there and will slide up and down with very little force.

Thanks everyone for your input.
