Prius (2001-03) :: Codes 3006 And 3014 - Replacing 1 Cell In HV Pack?
My Gen1 battery is giving up after 157,000 miles and I had a tech pull the engine codes which were 3006 and 3014 indicating SOC voltage even and cell #3014 going bad apparently. I started looking for a new battery and browsing these forums but started wondering if I could just replace 1 cell instead of having to buy a new or rebuild the whole pack. I'm sure it would be best to replace the whole pack with a Gen2 rebuild but money is an object so if I could get by with just a cell or 2 that might be a better route for me.
I didn't find an exact answer to this in the forums:
Does it make sense to replace just 1 cell? Might I get another 50,000 miles on it?
The car is driving but stops every 5 miles or so where I have to turn it off and back on again to get it to drive again. I'm sure it's not good to drive in this state but should I cease driving it immediately or risk damaging something else? I've been driving short trips for a day or two...
Prius (2001-03) :: Code P3125 - Bad Inverter
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) :: Whole Dash Lit Up - Code P3130
On my way home in stop and go traffic the whole dash lit up with about 4 miles to go. Car was running as normal so I immediately thought inverter pump so got home and checked for circulation and there was good circulation. Pulled code with my obdII scanner and code P3130 came up. Cleared codes to restart and check circulation of fluid to verify and there was NO CIRCULATION. So, went and ordered the Toyota part #G9020-47022. Is there something else I should check before just changing the pump like a relay or electrical? Is there another place to get the coolant as the dealer has it at $32 gallon which is crazy. Then, if I do end up changing out the pump which I am almost sure I will have to which is a good way to burp the system as I have read this can be an issue. Does all the fluid (parts guy says two gallons) need to be changed out or just what spills out.

I've got a shop in Az. One of my customers has an 02 with 489,000 miles. The problem is when you drive it about 5-10 miles the "red temp" light comes on then it starts to lose power. Pull over and shut it off for about a minute or two then it runs fine for another 5-10 miles. took it to dealer today and they said it needs a trans axle.
My question is why would it need a trans if it runs good until the "red temp" light comes on? Could it be just a sensor? What has gone bad?
Prius (Gen 1) :: 2001 - Keep Getting Code P3001 With All The Lights / ECU Failure
I have a 2001 prius that I bought from a garage . To get to the point, it had a dead battery pack so I put a good used one in. It will start and run but I keep getting code p3001 which indicates a bad battery ecu. I replaced the battery ecu to the original one that was in the car ,but I still keep getting the code along with all the lights. I did some looking and was told to replace the HV. ecu which I also replaced ,but it did not solve anything. I unplugged a harness while it was running and than got code p3100 which indicates HV. ecu failure.. So I am not sure what is going on ,talked to toyota tech and he said it does not need to be reprogrammed ,but you have to buy a new one as the vin # in the ecu will not match up..

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.
Prius (2001-03) :: HVAC Diagnostic Showing 21 Code
I am on vacation and the AC has stopped working in my '01 Prius. I have run the HVAC diagnostic and it shows the "21" code. The only thing I can find related to this code is the solar sensor fault. I have located the solar sensor on the dash but am not sure how to remove (to replace) it. I have gotten the little black cover off of it but don't know how the rest comes out. Does it just pull out or unscrew or do I have to squeeze some tabs or what?

I bought a 2003 that I was told was running it wasn't but it was cheap and only had 128000 miles on it so I bought it anyway. When I turn the key I here what sounds like the MG1 wants to engage but then nothing. Checked the codes, got 3125, cleared it, tried again, same thing. 12v battery is strong and everything 12v, PS, PB, lights etc., work fine with the key on so I don't suspect an inverter problem, but I admit I am not an expert so I'm willing to be schooled.
I don't have a scan tool that will give me sub codes but since this is gen 1 number 3, I also have 2 2001's that my wife and I drive, maybe I should look into purchasing one. I have an extra CVT out of a 2003, that was t-boned, that I know is good and I can swap it out if that is what I need to do. But before I do that is their anything else I should test to make sure I am on the right track?
Prius (2001-03) :: Getting Code P3006 But Voltages Seem To Be Good
I replaced a couple modules in my battery pack several months ago and it was working great until a few weeks ago I drove it after it had been sitting a couple days and it threw code P3006. I logged all the block voltages with Torque while I put the battery under load and found a potential issue but I'm not sure how relevant it is. Block 16 on on line 283 drops from 1624 to 1296(the refresh rate is rather poor so it's about 7 seconds between readings) while the other blocks only drop to about 1450. Is this significant or are anomalies like this normal? If this is an issue, how would I go about fixing it? I don't have the equipment to do a full rebalance, just a single channel charger. I did make sure that the voltages on the modules I replaced were consistent with the pack.
I plotted the data here.
Prius (2001-03) :: 2002 - Fixing Code P3030?

I just purchased a 2002 Prius from a government auction. The car had to be jump started at the auction yard. It ran for awhile and then died before I could put it on the dolly. I jumped it again, load it and towed it home. When I got home I jumped it and drove it off. I tried to charge the 12V battery on a 2 amp current, but it wouldn't charge so I replaced it with a new battery. Now the car won't start at all. Don't worry, I did not reverse polarity at anytime. Here's what is happening now....

I've got a 2001 Prius with a minor but annoying problem. It pops a P0440 code from time to time, always shortly after the gas tank is filled. Driveability/fuel economy are unaffected, and no other codes are ever triggered.
I checked for a cracked hose nipple on the "tank retainer", as posted by forum member kmc6566, but the unit on my car looked ok.

View 14 RepliesPrius (2001-03) :: Shuddering Transmission - Code P3125 And P3120?
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 have a 2003 Prius with a hard falt code of P3000 main battery bad! But there is not anything wrong with the batt or how it runs. I cleared the code and in 10 miles or so it comes right back? I was thinking of a reflash on the computer, what to do?
