Separate names with a comma.
It's aging, for sure, and is probably the cause of your problems. But it's not necessarily "toast." You can try charging it, as Bisco mentioned,...
Ditto the above. What load was on the 12V battery when you checked it? 11.8 on an unloaded AGM battery is essentially completely discharged. How...
I believe you need to install a test port on the Prius to measure fuel pressure, so it may not be "plug and play."
Some of the more technical DIYers will have another option or two. I think you're going through something many of us will be facing sooner or...
Did the dealership install that battery and botch it that badly? Is this a Toyota dealer? The cooling air ducts are extremely simple. I don't even...
It's a probably a bit more than an hour for a first-time DIYer. You have to dismount the relay block (two bolts). Then disconnect, unbolt, and...
Still, keep a close eye on the coolant and crankcase oil for a while. Plus, these cars typically start consuming some oil around 150K miles.
No, the warm day doesn't matter, as long as there's coolant in the loop. If things were out of whack, you'd hear gurgling sounds when you turned...
And keep in mind, it's very difficult if not impossible to drain the last two quarts out of the engine, so there will always be some diluted green...
I think you said you tried erasing codes with your scanner. Maybe your scanner isn't compatible enough with the Prius to allow you to do that?...
The Prius battery is the AGM type, which is spill-proof. Since the battery is within the passenger compartment, this is an important safety...
When you first turn the car on with a cold engine, you should hear the CHRS pump running for a few seconds. You should hear it again just after...
That method is better than the one I used back in the 70s, using a wood carpenter's ruler. It worked, though. I think you adjusted the toe-in...
You're posting in the Gen2 forum. If there's something specific to the 2011, you may not find out about it here. Definitely shop around. Friction...
Comments in red below:
Ditto, get a spray can of MAF sensor cleaner. Also some injector cleaner. The 13.8V you got was the charging voltage, not applicable here. The...
This is more likely to happen with the rear drum brakes. Inspect those as well.
Your primary concerns should be 1) where did the coolant go, and 2) why does the battery fan come on. The two tasks you're planning have little...
There's some confusion about the turbulence in the reservoir. The only place to see this is in the inverter reservoir, and this has no connection...
Your OP says, "As soon as I plugged it in to the OBD port, all the lights came on the dash and it shut off the ICE." Your post above says you...
