Prius (2004-09) :: Inverter Pump Noise Constant After Recall?

I recently had the inverter pump replaced under recall. it now makes a the pump noise even when I am driving. I hear it when car is not fully warmed. Back when it had the original inverter pump, it only made noise at startup and shut off.

Prius (2004-09) :: Seems Like Inverter Coolant Leaking

So, the sideways coolant tank in the engine compartment, not the one next to the grill, but the one that is sort of between the air filter box and that shiny metal square

I have always thought that tank was slightly low, but it has a seam just about where the full line is, so I was never sure....finally about three weeks ago, I worked up my courage and put a few ounces of coolant in that tank. THEN it was up to the full line.

So, a few weeks after adding the coolant, I had the water pump recall done. Now the coolant level is back down to where it was before I added....so I am assuming that the correct level is just below that seam that seals the top of the plastic tank to the bottom part of the tank.

Prius (2004-09) :: Inverter Pump Noise - No Circulation

I have a big red triangle on the pump is making noises not loud noises sounds like it's operating correctly there is no turbulence in reservoir and when I squeeze the hose the level in the reservoir goes up-and-down which leads me to believe there is no blockage in the pipe coming out of out of the pump.

My handheld scanner and torque on my android tablet only gave me my oxygen sensor code which I know about and I'm going to replace when the weather gets hot I am wondering if the coolant pump would throw a code that these devices would be able to pick up or do I need to go to the dealer or find a shop which is capable of reading the HYbrid codes?

Prius (2004-09) :: Sudden Rush Of Failed Inverter Coolant Pump

We seem to be getting reports of failed inverter coolant pumps here on just about a daily basis. I'm wondering if they're all just failing now or if this is something of a "backlog" of failures that started in Winter but are only really being detected now.

Prius (2004-09) :: Inverter Coolant Pump Failure / Warning Lights Came On

My 2007 Prius with 162k miles had an Inverter Coolant Pump Failure Monday 6.5 hours from home when my wife was driving it home from a trip. Red Triangle, (!), vsc, and check engine light. She was able to make it about 20 minutes to a dealer where it was diagnosed. Luckily no further damage was done to vehicle. Yes, she should have stopped but continued on since car was driving OK.

Prius (2004-09) :: Inverter Coolant Pump Failure - P0A93 Code

I own a 2006 JDM prius with 323,000 km. The inverter coolant pump failed recently (got P0A93 code and no agitation in coolant reservoir). I ordered a replacement on eBay and am awaiting arrival. I may need to do some light driving in the in the interim and am thinking about installing a 10 inch fan in the space between the inverter/transmission and radiator to keep things cool. Is this wise or should I just let the car sit until the new pump gets here?

Also, I am burning oil...I usually have to top up 1 to 2 quarts in between changes. Is there anything I can do without tearing down the engine? A friend of mine suggested using Lucas oil stabilizer the next time I change oil...could this have any negative implications?

Prius (2004-09) :: Turn Off Red Triangle After Control Valve And Inverter Water Pump Installed

I had the red triangle pop up on my Prius. I codes I got P0A93 and P1121 I needed a new control valve and inverter water pump. I installed both the valve and the inverter pump filled it with new coolant and bled both systems.

I went into maintenance mode so I could run the motor and bleed out all the water. My question is the red triangle is still on in my car when I start it up.. Is there some way to clear the red triangle or does it just go away on its own? Not sure what to do.

Prius (2004-09) Fuel :: How To Determine If Inverter Pump / Coolant Reservoir Is Not Working Properly

How do you know if the inverter coolant pump/reservoir is bad after the recall was performed?Since it doesn't produce any codes but can reduce the electric-drive if getting too hot, how do you convince Toyota to give it a second look?

Prius (Gen 2) :: Inverter Pump Won't Pump Air

If you drive in 100 degree F weather, use your AC and drive up steep hills. Check your inverter coolant system for trapped air. The inverter pump cannot pump air. I had the LSC about 6 months ago and apparently the mechanic rushed the job and there was still an amazing amount of air in the system, I did this yesterday. Today I checked it again and no more air showed on my clear plastic tubing. Although I had to top the reservoir with 2-3 more ounces, so air could have expelled out of the reservoir and I would not notice it.

Gen 2 Prius :: Inverter Coolant Pump Failures

Having seen the rather catastrophic outcomes that are possible with inverter coolant pump failure, I've thought a bit about adding a flow sensor in the coolant path. I even went so far as to buy a flow sensor, which would probably do the job. However, it's somewhat heavy, and then there's the plumbing job to take care of. Seemed somewhat challenging to pull off.

Since this aborted endeavor, I began thinking about ways to detect surface turbulence at the top of the coolant tank, and am now thinking that might be easier to pull off, even if it requires programming a PIC to do the monitoring. My current thought is to install an LED and optical sensor in the cap, and measure light intensity received.

Prius (Gen 2) :: 2008 / Inverter Coolant Pump Leak?

I'm a new owner of a used 2008 Prius. Car only has 67K miles and other than the leak, appears to be in good shape.

I noticed the coolant was low in both reservoirs, filled it up (with the proper SLLC), but a day or so later the check engine light came on. Took it to mechanic (dealer is 2 hours away), he read and cleared the codes, then found the leak. Appears to be leaking where the lower hose attaches to the pump, so not sure if it's the pump or the hose that's the problem. I've also noticed that the pump seems a bit noisy for a few minutes after shutting off the car (of course, I'm new to the Prius so not totally sure what "normal" sounds like).

Prius (Gen 2) :: Inverter Pump Failure - Code P0A93

While driving home last night the Red Triangle, CEL and the Hybrid Warning lamp, (on the MFD) all lit up. The cruise control also shut down. We stopped and checked the manual to identify what the symbols meant. We were approximately 90 miles from home, drizzling rain and it was about 60 degrees.

Prius (2001-03) :: Losing MPG After Inverter Pump Replacement

After the warning light & triangle went on in my 2003 Prius, it turned out the inverter pump was bad. It was replaced. Now I am steadily losing MPG as I drive the car. From before the replacement, it has gone from 42 - 44 down to 36. This is in a few days time.

After I got home, I saw that the dealer put on the service ticket that the car might need a new inverter. There was no reason stated for that, and the service rep never mentioned it. In fact, the service rep said that the hybrid system would not be damaged if I drove the car with the warning light, since the hybrid system would shut itself off before any damage would be done.

There is a small leak in the radiator but on inspection, the coolant level is full (actually, while still hot, it is overfull), so I don't think that is the problem, at least not yet.

Prius (2010-12) :: Water Pump For Inverter Unit

In service manual doesn't show the limit time to change the water pump of inverter unit. What is the limit time or limit mileage for change it?

Example, engine's water pump has the limit around 200,000 Km(125,000Mile). But why inverter water pump no limit using time?

Prius (Gen 2) :: Inverter Pump Damaged - Car Dead, No Warning Lights

I own a 2007 Prius last Friday I was driving on the freeway when all of sudden the car died on me without any warning lights. There was a bad burning smell which later I realize it was from the inverter coolant pump. I was luckily able to mange to pull on side. Towing was another pain because the car wont turn (start) or acc so you can't shift to neutral and the front wheels were locked.

Took it to Toyota they refused to cover any work because inverter pump was replaced by the previous owner about 2 years ago. between that there is hardly 20k on it.

Now the car wont start. I checked the main fuse on auxiliary battery and its working fine. The interior lights are turning on, alarm and key fob works, power locks working. but it wont start.

I heard there is a fuse that will be tripped by the coolant pump it's 15A AM2 fuse. I don't know where is that fuse. I can have the pump replaced but need to know how to tun on the car. A local mechanic came to check and he said that main relay showing current only on battery side but not towards inlet (going to engine or car).

Prius (2004-09) :: One Of The Water Pump Is Leaking

I learned today there are at least two water pumps in my 2006 Prius, and that one of them is leaking. I had the recall done for the electric motor water pump in November. Now, during my scheduled maintenance, they tell me my second water pump has been leaking (slowly). My car has 132,000 miles.

Prius (2004-09) :: Water Pump Was Leaking

I just got back from the dealer and was told my water pump was leaking. I was told it was a small leak and that it could only be seen by lifting the car. I opened the hood and noticed some pink crusty looking thing on what i believed to be the water pump. I took some pictures of the water pump, the radiator and overflow level. If you look closely you can see some of the pink crusty stuff around the pump. I poked it with a pencil and it broke apart pretty easy.

First of all if that pink crusty stuff is anything i should worry about? Also if the levels of the fluid in the radiator/overflow tank are good? Is there another sure way i can tell that i even have a water pump leak? I searched around the forum and it looks like the hardest part about replacing the water pump is getting the air out of the system and that the dealer quote is a rip-off.
