Nov 2, 2010
Could a bad transmission cause error code P3030 and P3009?
This car has no other symptoms other than the Mil light and the check engine light.

Prius (2001-03) :: Way To Diagnose P3009 Error Code Source
The first step is to clear the P3009 trouble code by unhooking the 12V battery for a moment or using a code reader. Now turn the key on/ but NOT start/ready mode, wait 30 seconds and if the code comes back, the leak is in the battery case. If the code does not return, turn key to start to "ready mode" and immediately shift to neutral and stay this mode for 30 seconds. If the code returns, the leak is in the power cables or inverter. If the code did not set, shift to drive and if the code appears now (can take up to a minute or so), the leak is in the transaxle. This is something that can be done in a few minutes without a scan tool or "megger" while never removing any components and not leaving the driver seat.
Ideally you want 3009 in battery case. That might be fixable without buying anything, just take apart battery and clean bus bars etc. If your bus bars are really "gooey", new ones are available from the dealer for a couple hundred bucks. Inverter is harder to replace, transaxle is the hardest.

Prius (2001-03) :: 2002 - Fixing Code P3030?
I picked up a 2002 Prius with 164k, still on original battery. It giving code P3030 which evidently relates to a high voltage line snapped on the bus bar.

A warning came on the display with the words "PS Main" and a picture of a battery. I took it to a dealer and he gave me the bad news: I allegedly need a new hybrid (main) battery. The diagnostic code was P3009--I didn't know about sub-codes, so I didn't ask if there were any. P3009 means that there is an electrical leak from the main battery.

2001 Prius
I was able to pull codes this evening ( no subcodes).
The codes are as follows:
P3000, Battery Control System Malfunction
P3030, Battery Voltage Detective Line Snapped
Will the P3030 cause a P3000 to pop up since it appears I have one of the 19 voltage detect lines corroded or broken?
Once I fix this issue, is there a chance that the P3000 will disappear?
I was just getting the triangle and the Main Battery error on the MFD up until yesterday. Yesterday, the ! with the car came on (Hybrid system) on the MFD. I did not check any codes until today. Car will currently not start at all.
Aux battery voltage is confirmed to be 12.3 volts via the MFD in the diagnostic mode so it's good to go.
No one around has a scan tool that will also pull the subcodes.
Prius (2004-09) :: Code P3030, Check Engine Light Came On
we have a Prius from 2004.
We have had problems with the starter battery. This is because the car is so rarely driven. So to fix this I have charged the battery several times. But have not disconnected the battery cables before. I don't know if thats the reason why we have problems though. But you can suspect that.
One morning when we should drive the car we saw that the "check engine light" came up on the dashboard. And other warnings also.
I bought an OBD scanner and hooked it up. P3030..
So I took the hybrid battery out of the car and cleaned all poles and connections. I measured each battery cell to approx 7,6 V.
I also bought a new starter battery. Now, I have put all together again. But P3030 is still the case.
Is it possible to measure the voltages from the busbar module by measure on the contact to the ECU? I have tried that but don't get stable results. The voltages goes up and down all time..
My last hope is that a wire between battery busbar and ECU is broken. But I couldn't recognize that when I had the battery out of the car.
Prius (Gen 2) :: 2004 - Red Triangle And Hidden Code P3009-526
I picked up a 2004 Prius with 150k. It has no check engine light and no codes with a scangauge. I hooked it up to a mini-vci with techstream and found the following: P3009-526, C1310 and B1421. The car will only start if you reset codes, then after a few minutes of running the red triangle comes back.

I bought an '04 prius about a month ago and it has already been at Toyota for over a week. It get's the red triangle, the yellow brake light, and the hybrid red car on the screen and says Problem! I took it to the dealer and he pulled the codes P3009 and info code 526. When you open the hood, the inverter overflow tank is boiling, so it must be overheating. I have read about the pumps going out and when the engine is cool there is turbulence in the overflow tank.
The guy I bought it from did say he had replaced the water pump recently. Toyota kept it for a week trying to replicate and couldn't, and even had the regional rep look at it.
Prius (2001-03) :: Loud Hum During Regen Breaking / Low Mpg - P3000 And P3009
Bought a used 2002 Prius in December of last year. When I got it home the hybrid system warning light and the check engine light came on, but after reading through priuschat for a few hours I thought to take a look at the engine air filter, which turned out to be utterly filthy. Replaced it and the car ran fantastically for the next 8 months, which was plenty of time for me to fall utterly in love with how quiet it is and how smooth a ride it is.
The carfax report for the car showed that its battery was replaced shortly before I bought it and that its transmission fluid was changed approximately 20k miles before that, so I thought (apparently mistakenly) that I didn't have to worry too much about either.
During these 8 months the car saw my regular mechanic for oil changes twice, had a bad CV axle replaced and I was told the serpentine belt was glazing and may need to be replaced with the next oil change, but neither I nor my regular mechanic noticed any other issues.

View 1 RepliesPrius (2001-03) :: P3100, P3125 Error Code Came On
My Wife was driving our 2001 Prius and got the big triangle and the car went into limp mode.
The Codes were P3100 (info code 196) and P3125 (info code 325)
P3100/196 = Internal Error - Generator CPU Malfunction
3125/325 - Inverter Internal Short. - Generator Inverter Fin - Inverter Internal short
Clear the codes and the car runs fine, but the problem will eventually resurface.
The dealer wanted tor replace both the converter/inverter and HV ECU.
I purchased replacement converter/inverter from Ebay and inverter coolant pump (new) and installed.
Problem eventually resurfaced. I purchased replacement HV ECU from ebay and installed.
Engine would not start (does not attempt to even turn over), but was not throwing any codes. I had this same symptom with a third HV ECU as well. The part numbers on the HV ECU were exact matches.

This summer my power steering went out. I replaced the steering rack with a remanufactured rack, which failed. I got the replacement rack replaced by the remanufacturer and installed by a different shop. Same problem: SEVERE vibration when turning hard right followed by the PS error code, or just little twitchy motions when driving. I'm having the second shop take a look at it again this monday as I suspect that this is a data processing issue.

Working on a 2002 prius with 153k miles. bought it with a "Bad transmission" diagnosed by toyota dealer. Got I home and did a quick check but there were no codes. I drove it about 50 feet into my garage where it would shudder badly while being driven which from my experience sounds like a bad MG2 motor. Drained the oil and thought hhmmm th oil does not smell bad and neither did it look burned. Proceeded to pull the mg2 but found it looked brand new, no burned spots or any such thing. SO I put it back together and think its a bad invertor. put on a different invertor that I have lying in my garage that I "think" is good and start the car. get code p3125 and p3120 and still have the bad shuddering when i try to drive it..Is there any way to test it further before I pull the trans and put a new trans back in?

I recently purchased a 2001 Prius from a state fleet auction. The car has 121,000 miles and was in the non-running part of the auction. It had been sitting at least four months. I decided to give it a go since it looked to be in decent condition.
It did not start because of a dead 12v battery. I bought a replacement battery, but it still did not start. The screen showed ~ 1/8 hybrid battery. The warning lights illuminated and it was never ready. I plugged in my code scanner and a P3030 code came up.
I got it towed home and started working on it. The P3030 code signifies a high voltage line snapped .

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

I've checked the lines from the Purge Valve on the Passenger side of the Intake Manifold, Check OK
I've Checked that Valve OK
I've Replaced the Canister Close Valve
I've got the Gas Cap tight.
I've removed the rubber bushing holding the CCV to the Evap Canister, hoping to isolate the Filter and point the blame on it, no luck there!!
I'm thinking next is to drop the Tank and check over all the Goodies on top.... as much as I hate the thought of that, the two access holes under the seats, just don't allow access to enough of the tank!
any thing there that I could suspect, I see there's a check valve!
There's also the Fuel Tank Pressure Sensor, which may be at fault.
