hi Patrick you help med with my Prius in the past. I am again facing some issues.
2013 Prius Plug in with 125K miles. changed thermostat and placed in maintenance mode ever since keep displaying check hybrid system stop at safe place. seems like something got lose or something during the repair causing the warning

Hey I saw a post that you commented on the difference between the 2 battery sizes of the Gen 2 Prius. The bigger battery, the S46B24R, was for the smart option and the other smaller battery, the S34B20R, was for the regular Prius.

I by accident bought the bigger battery, the S46B24R, and installed it in the regular Prius.

I was told you could help out with Gen 2 issue c2301, 40, 10 and 581 transmission ecu. I've done everything just not swap the transmission and I've gone through all of the mentions in this forum. I was told you mentioned about a bad ground or loose wire on the ecu a few years back. Thanks in advance

Any thoughts here ? See the last post

First, thank you for your informative and thoughtful posts. I came across your thread from 2011 (from https://priuschat.com/threads/dashboard-lights-not-working-other-weird-things.100741/). You make two posts relating to...

1) combination meter

2) AMP2/inverter pump not working.

Which is it? or is it both?

Thank you.

Hi , I saw a post you had for a gen1 no start. Had same issue ,
runs for 7 seconds dies. Put in neutral and is idles but rough. Main battery is low but now runs rough in park but is running, on couple cylinders Not sure what’s goin on. I’m going to let it run hopefully charge the main up

Hi Patrick
Been a fan of yours for a long time.
Good to see you are still active and solving our problems.
While replacing the heat control valve, about 3 qt of coolant leaked out( i think from the very bottom hose}
In attempting to pour the coolant back into the radiator directly, it only took about a pint-no more.
What are the steps to get more in?
much appreciated for your help.

Pete

Hello Patrick, I was wondering if you could help me with a U0293 error caused by a short on my 2012 Prius Plug In.

Maybe you have some residual air trapped in the engine cylinder head?

Hello Patrick, recent I have replace my prius v 2012 engine, all was well but I noticed the coolant heat sign is on, plz help me

here are the codes
DTC
U0293
UO100
U0101
U0151
U0164
U0293

I suspect the spark from the coils may have arced and fried the computer. I barely know how to use techstream but here is what I got, I hope you would be kind enough to provide some guidance as to how to tackle this. If It is the ECM can I just replace it or do I need to program it?

Hello I see you have a bit experience with tech stream. long story short. my engine has bent rod I will be replacing it its a 2010.
in the process of putting it together I rolled it off the roll up ramps and it started but soon died.
as engine grounds were not connected and it had no plugs and coils were dangling on the side.

Hi Patrick, as you know you are an valuable resource on Prius Chat. You have helped me before. I have a quick one this time: I want to buy a VCI dongle that will allow me to use Techstream with my Toyotas (I have a Sienna and a Prius). There are way too many to choose from on Amazon, do you have a brand / vendor you can recommend (or maybe a link to one that it legit)?

I’m wondering if the financial outlay ( at least $2000 ) makes sense given the age and miles of the car . The fact that the hybrid battery and AC are pretty recent make me lean toward making the repairs

Hi Patrick ,
Please advise on my 2006 Prius . It has 128,000 miles and needs a new brake actuator and left axle cv boot . .
In 2016 , I replaced the hybrid battery with a new one and replaced the AC .In 2018 I bought new Michelin tires and had brake pads replaced .

A new actuator is $1200 .. the cv boot part is $75 or cv axle and boot kit $528 .Labor at a non dealer hybrid repair is $109 an hour .

Hello Patrick,
Can you offer any advice or tips on how to separate the CHS water pump electrical connector on a 2006 Prius? Thank you. Peter

Hi Patrick, I see your name come up a lot and hope you might be able to advise me. I recently had an inverter pump fail on my 05, pump has been replaced, am2 fuse replaced and car now operates again except that the a/c doesn't work. is there a procedure to restore power to the a/c after the inverter has shut it down?

Hi Patrick I was reading some of your post to a fella that had a code problem POA A6 and attached to it was the 526 code as you troubleshoot it you were looking for another code mine also has the 612 code is wondering if you might be able to help me determine what that is thanks have a great day
