Sudden loss of power, Red Triangle, Won't Start + P3190

Yes, I didn't think of that. I can attempt getting a warranty replacement, however, I'm skeptical they'll honor the repair based on the problems with the car I've had thus far. I suppose that may be my best route before getting a new one put in.

 

So basically I've screwed myself. Do I attempt to contact Best Hybrid to see if they will come out for a swap? I hate to run the risk of voiding my warranty, but if it IS the battery, I'd prefer a free repair over $3500. However I still highly doubt swapping the battery will fix the issue from what I've learned.

I don't know if they're running Techstream over there. I'm trying to be polite and not act like I know everything (because I don't) Just trying to determine the most logical solution at this point, none of which are perfect.

 

Right. And as far as I know, my mechanic is not getting any of those codes. I will check again to be sure.

 

They did tell me the voltage was about 140v.

 

Alright friends, I was able to get a little more information and they have done quite a bit of troubleshooting.

- They checked the MAF and throttle body. All good. They cleaned them anyway to be sure.
- They replaced the 12v battery to be sure it was not anything weird related to that.
- They pulled the battery out and checked the individual cells to see if there was any drop between cells. A couple cells have a 5/10 drop and 8/10 drop ratio.
- The computer is throwing the following battery codes: P3000, A080

To me, this confirms that I will go ahead and have my battery guys do a warranty replacement to at least get me back on the road. I can decide what to do from there. I don't want to get stranded somewhere else.

 

Sorry, what I meant is there is a much higher voltage drop on some cells than others.

 

Correct. Today I had my Prius battery guy talk directly with my mechanic. He said basically the same thing you said - the battery has been worn down due to the engine issues and repeated attempts to start; so now I have two problems to solve. Luckily, he was incredibly gracious and said he would come out to the shop and swap out my battery with a new (rebuilt) one. But then it’s back in the mechanics hands to determine the actual engine problem. I’ll leep you posted.

 

Hello everyone, an update....

Had the drained battery replaced with a new one; which is frustrating to say the least.

The mechanic is stumped. He has done the following:
- Cleaned the throttle body
- Cleaned and also tried a new mass airflow sensor
- Replaced the 12v
- Replaced the faulty ignition coil

He noted he can keep the car running if he uses carb cleaner. Next steps would either be throttle body replacement, (which he does not think is the issue), or the fuel pump or fuel injectors. He's just shooting in the dark at this point and recommended I bring it to Toyota. They use the Snap On Zeus to read codes, so he's not getting enough information to fully diagnose the problem.

I'd rather not have it towed to Toyota because it's going to cost me an arm and a leg to get it repaired. I'd prefer to diagnose the issue myself and then have my mechanic fix it. Unfortunately, my Techstream software doesn't arrive until next week. Before this occurred, I had been experiencing lots of engine ping, and maybe that is related to this issue.

My mechanic has not charged me for anything besides :30 of labor since he feels bad. But the battery replacement thru Best Hybrid Batteries has cost me quite a bit. Just trying to avoid more crazy costs.
