Prius (2001-03) :: 2002 - P3125 Sub Code 325 With No Start / Inverter Failing
Pulling into parking lot and the triangle and exclamation light appear on dash. Drive about an additional hundred feet with what felt like lower power and no noises.
- Check 12V after about an hour and it reads 12.4 volts.
- Read codes and get P3125 sub code 325.
- Temperatures and HV battery numbers all looked good.
- Clear codes and immediately code comes back with no start, nothing. Did this many times.
This code and sub code lead to the inverter failing. Being that there was no noise as a MG2 stator failure this also leads to an inverter failure right as the MG1 motor starts the engine? Inverter pump still running good as it was recently replaced along with ATX fluid. Within the last two weeks two HV modules have been replaced.
Prius (Gen 1) :: 2001 - Inverter Coolant Leak?
My 2001 Prius with 134k miles has been running great but leaves a small amount of coolant on the ground after parking. I've had to add approximately 8 ounces per 100 miles.

I bought an 01 Prius with 148k miles. It had code P3125 which mean bad inverter. I replaced the inverter with one from a junk yard with 81k miles. As soon as I was done the car started right up, and I didnt get electrocuted!
Right after the car started I got codes P3115 P3001 and P 3191. I cleared them out and turned off the car for a min.
When I started the car again I got codes P3030 and P3001.
This car has an extensive service history, It has a new Cat and exhaust, a new accessory and HV traction battery that are less than 8 months old. Crank position sensor is new. fuel tank is new.
What could be causing the P3030 and the P3001?
Prius (2001-03) :: P3130 Error Saying Inverter Overtemp
Toyota ticked me off. I had them repair the ac on my Prius and during this time I read bleeding the inverter coolant can be a pain. They said they would flush and fill the inverter coolant for me. Over the weekend I get a P3130 error saying inverter overtemp. I did not have "turbulance" in the reservoir when I first bought this car and didn't know much at the time. Now, with getting the code I looked into this deeper. I told Toyota that this repair had been skipped and they denied it. Ends up the fluid was lower than it should and the tech said the pump wasn't working. "How did you bleed the system then". They gave me 2 gallons of coolant and I told them I will repair this myself now.

Hot or cold? I just changed the fluid so should I adjust the level when cold? And with the pump off I assume?
View 1 RepliesPrius (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 (2001-03) :: 2002 - Gas Mileage - Replacing Coolant And Inverter
I read in the owners manual that the engine antifreeze should be an ethylene glycol type. I believe that Prestone makes this type of coolant in a 50/50 mix. Is that correct? Also, what type of coolant does the inverter use? I want to try and stay away from buying it at a dealer. Also, my gen 1 has 117,000 miles and I must admit that I have been slacking with the maintenance. My gas mileage is down to 40/mpg compared to 48-49mpg when I got the car two years back with 40k. I am pretty sure the original auxillary batter is still in it, so I order a new one today. I also plan an changing the transaxle fluid, PCV valve, air filter, and cabin filter. The plugs where changed at 80,000 miles. Where can I order a gasket for the transaxle pan? I intend on dropping it and cleaning it out. Do you think this will get the gas milage back up?

2002 Prius with 94K gave me today P3130, after I tested the Inverter Water Pump I found out that it bad but until I go to the dealer in order to buy the part $147 he was closed. the question is can I drive with the car like this bac home (65 miles) and if I turn on the A/C the Engine will work all the time right? And also after replacing the Inverter Water Pump how can i tell if the problem solved?
View 14 RepliesPrius (Gen 1) :: 2001 Toyota Inverter Cooling Pump Fault Code P3130
I have a 2001 Toyota Prius. The inverter cooling pump was dead and I had the P3130 fault code. I replaced the pump and the refilled the fluid. After more than 4 or 5 times bleeding the system, now the pump sounds funny. It sounds like a water fall and look like it has too much air!!!! I can’t see any turbulence in the reservoir tank either.
There are 2 bleeding valves on the front side of the Inverter. Which one should be used to for bleeding the system? Both?
Does the system have any thermostat that could cause problem? Does it use the same radiator as the main one? What could cause having NO turbulence? I think the new pump will be dead too if it can’t make the turbulence.

Prius (Gen 2) :: What Is The 12v Charging Amperage Of Inverter
what is the 12v charging amperage of the gen II Inverter?
i just bought a 07 Prius with 43k
i am into ham radio and i will be installing a handfull of ham radios, including one that on high power can draw as much as 20 amps from 12v system during transmit.
all the radios in receive mode together draw about 6 amps.
im used to traditional alternator ratings of 50 70 90 and 100+ amps but upon searching this site, i have found no info about the 12v battery charging systems amperage output.
any one have specs on the 12v charging system output?
Prius (Gen 3) :: 2010 - Missing Cover On Inverter
I just noticed my 2010 Prius doesn't have the plastic piece/cover that goes across the inverter. I posted a picture of the black plastic/metal? piece/cover. Would any service require the removal of that piece? Only thing I can think of is the Dealer replacing the recalled brake pump assembly.
View 5 RepliesPrius (Gen 3) :: Inverter Coolant Reservoir On Low Mark
I have had my certified 2010 Prius since June 2015. Last Saturday I noticed my inverter coolant reservoir was on the low mark. I went to the closest dealer and they topped it off up almost to the full mark for free. I thought it had probably went down from evaporation and I just hadn't noticed it before. Yesterday I went back to the dealer where I purchased it which is about 90 miles away to have the CVT fluid changed. This morning the coolant was back down to almost the low mark. I looked on the ground and can't see any evidence of a leak. Tomorrow I have a appointment to have them check it. Since it is still in the one year certified warranty I don't know how motivated they will be to find the problem when they can't charge me for it. I don't think the level would have went back down right away if there wasn't a leak somewhere. I checked and there have been no recalls done or called for on it.
View 12 RepliesGen 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 (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.
