Prius (2001-03) :: P3006 And P1259 Codes But No Loss Of MPG
Oct 29, 2012
Check Engine light is on but car seems to be running OK (getting 40mpg). I do notice that the car seems to rely on the Gas more than the battery than it used to.
My question is, will MPG start to drop gradually until one day the Traction Battery is just dead or will the car go from running well to not running well in minutes.
My shop says it needs a battery but it's not in the budget at the moment so I need to see if I can postpone it until the new year.
2003, 145k, just bought it 3 months ago

Here is my situation- back in 2014 I had a local mechanic replace my HV battery and 12V battery after the Red Triangle of Death. Well yesterday that triangle reared its ugly head again! (and cruise control stopped working) Since this mechanic has 3 year, 36,000 mile warranty on all parts and labor, I figured this should be covered. I drove my wife's car to work today, then after work drove the Prius over there to find them closed until Friday!
So I had the guys at Advanced Auto read the codes for me and got P3006, C1213, and C1259. I have done extensive reading and researching, much of it on this site on these codes, but my main question is this:
I commute about 20 miles one way, and on certain days my wife commutes 10 to 22 miles the opposite direction. There are 3 days we go opposite ways this week, and at least one that is completely unmanageable without 2 cars.

I have a 2001 Prius with about 110K which I have owned since new. It displayed the hybrid warning light (as well as check engine) 2 weeks ago and I took the car in to the local dealer.. After a little muddling around they came up with codes indicating that the computer for the battery was going. I purchased that Part Number: 8989047030 Part Description: electrical, battery, computer H.V. SUPPLY. and the dealer installed that part a couple of days ago.
Now the following codes (and only these codes according to the dealer) are displaying and indicating faults in the main battery: P3006 and P3000.

Need to diagnose a problem with my 2001 Prius. I was driving it on the highway when suddenly the hybrid system warning light and the main battery light, along with the check engine light came on. I pulled over, turned off the car, and turned it back on. The main battery light error cleared but the Hybrid System warning light stayed on as did the check engine light.
I took my car into the dealership and they told me that the 12V battery was probably low at some point but that they didn't find any problems.
The error codes that came up were: C1215, C1241, C1259, C1521, C1522, C1558, and C1559.

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.

Our 2002 just ticked over 200,000 miles and now has the dreaded triangle and DTC P3006 (uneven SOC in HV battery). It putters around, but the MFD is lit up with alarming icons. I cleared the code once, drove two miles, and turned the car off. On the way back home it came back on. We have owned it a few years, the previous owner was a mechanic who bought it at auction, replaced some of the cells and flipped it.
I can access the block voltages, but they don't point to any obvious culprit. I'm also using EngineLink with a PID list adapted from Gen 2.. so the formulas might not be appropriate. I checked both running and engine off, and both times Block 6 was slightly lower.. on the order of .02v. From what I understand, it takes .3v difference to throw the code. Of course the only real test would be under load.. so I don't know what to make of this. But, am I correct in believing that P3006 specifies a problem in block 6, or is that a general code?
The DeltaSOC is 51%. Again, I can't vouch for the math, but this seems pretty high.

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 have a 2001 toyota prius with 130k miles on it. 4 days back the triangle of death showed up on the dash board. The car would run fine for 3-4 miles, then brake light (on the dashboard) would turn on.
Sometimes the car would run fine with the brake lights, other times it would really slow down. Turning the car off and then on again gives me another 3-4 miles before the same story repeats again.
This triangle of death used to appear earlier too(6-7 month back), stay for few hours and then magically disappear, but this time I m not so lucky.

I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?

I have a 2002 primus and got the p3006 code.
Engine would Rev and got all the lights. I figured it was the battery and decided to get a Dorman replacement. I replaced the battery but turning it on I would get the p3006 code after a few seconds. No lights at that point. I would drive about 10 miles and would get all the lights and a second p3006 code. I would clear the code and it would get rid of lights and car would operate normally.
Sometimes the lights would come on and the brake light would also come on and the engine would rev. sometimes when that happened I would get code p3012.
could the battery be OK and it be some other problem? I thought p3006 was the bad battery code.

2012 v five with 56,500 miles. Getting onto an on ramp and accelerating when car jolted and dramatic power loss. I posted a thread about my car "ticking" as I slowed down from 30mph and I am wondering if this was related. I had no choice but to drive it home and kept car under 45 mostly on side streets. Car is not assisted at all by electric motor and can barely go up hills. With windows open and attention to any unusual sound i noticed no more ticking when slowing down from 25 to zero.... I think its covered under warranty at least powertrain, hopefully. I know a few of you here have the ticking problem to so i will update if this is related after i bring it in for service.

I need to get my 2002 Toyota Prius inspected. The Warning/check engine light came on so I ran a diagnostic (OBDII) on it and came up with P3006 Fuel Air Metering Auxillary Emission controls. What does this mean? Previously codes indicating cylinder misfire came up but those cleared.

I began to smell gas or oil in my car, so I went to Autozone and they couldn't turn off my engine light. They gave me error codes & possible causes for the problem.
P1259 - vtec system malfunction
Probable cause:
aa1: Open or short circuit condition
aa2: Vtec solenoid valve fault
aa3: Vtec pressure switch fault
aa4: blocked oil passage
I have about 140K miles and I change my oil every 3-5K, but try to do it closer to every 3k miles.
Based on the smell, I'm definitely leaking oil & burning through it too fast, but I don't know how serious that is in terms of repairs.

I bought my 2001 Prius used about a year and a half ago and had no problems until the past couple of months. On three occasions now, the triangle warning light has come up on the screen while I was driving and the car wouldn't accelerate when I pushed the gas pedal.
Fortunately, the I was able to coast to the side of the road on each occasion, and when I turned the car off and restarted it, it worked fine. The first two times, it happened on the freeway after a lengthy drive and while traveling at about 70 mph. Today it happened on a surface street, but after I had been on the freeway (in gridlock) for nearly an hour.
I should have dealt with this sooner, but somehow every time it has happened, it was on the weekend and/or when I was out of town, so I couldn't immediately take it to a shop, and since the car started back up immediately and ran fine after each occurrence, it didn't seem urgent.

I've been having this problem where as i'm driving (mostly highway) all of a sudden I get the feeling like i've let go of the gas pedal but I haven't. The mpg meter goes from about 40 to 100 as if its on straight battery power and I have to really press the pedal down to get any decent acceleration. Once in awhile i'll get the big orange triangle warning and the little pic of an exclamation point in an outline of a car. But after a day it may go away.
One time it didn't and I brought it in. I spent 80 bucks for them to find nothing wrong and say the alert had something to do with an oxygen sensor (its was awhile ago, i dont quite remember exactly)

My daughter has a 2001 Prius with about 165,000 miles on it. She was driving it and the red high temp light came on and stayed on. She also said that a few minutes later she lost power. She stopped and turned it off. Waited a few minutes, and started it again. The light went off and she drove it home about 5 miles. The light came on when she got home. No engine codes. I changed the thermostat. I filled it back up with fresh antifreeze and water and took out to test drive. No leaks. 2 miles down the road the light came back on. I stopped and checked it. upper radiator hose, hot and lower hose cold. Radiator not warm. Blowing out hot air with the heater. I think the water pump belt is on, as i am at work right now but will check as soon as I get home. I took the old thermostat and put it in a pan of boiling water and it opened, so apparently it was the thermostat.

This just recently started happening just shy of 200k miles, 14 years. While driving down the road, suddenly notice a power loss or no power, i.e., no motor output. Sometimes the just the ICE won't accelerate, sometimes it's both ICE and Electric motive force. When this occurs, the Brake and ABS check lights turn on. After a few seconds, to 10's of seconds, then the motive power reenables and the Brake/ABS lights go out. Often the cars continues on with no repeat. Testing over a few drives, it seemed to only do it during the warmup cycle when coolant was near 160-170.
However on a drive in the afternoon after it occurred in the morning; with ambient around 30 degrees, windows cracked, interior heat off, it didn't occur on the 15 minute drive, mostly freeway speed, even after about 10 minutes and cranking interior heat on. No codes are registered when this happens. I used Torque Pro and monitored things like throttle position and such, and things there seemed normal. Eng rpm dropped under 1000rpm and wasn't steady. Watching the MFG the power flows responded to the throttle (pushed/released) as if the engine was still doing what was asked (go figure, the display shows what is commanded, not what is occurring?).

A 2001 Prius is getting a warning triangle. No check engine light, and with my OBDII scanner, it shows there are no codes. I can erase and the triangle goes out, but it comes back on eventually. It seems only if the car is driven a long time/distance it comes on, indicating some heat issue perhaps.
The 12v battery is good, the radiator coolant is good, the inverter coolant is good and flowing. The washer fluid hose is broken, could THAT give the death triangle? There must be a way to have the cars display whats wrong with the fancy software and touch screen?

I have no codes on screens, engine revs and gas mileage has gone down to 30 mpg from 40s this summer. The toyota service adviser said the poor gas mileage was from running the heater since it is around 20 degrees these days in minnesota. My innova scanner shows no DTC's. But my question is do I need a scanguage II or other scanner to get the battery codes? Am I missing them using the innova scanner? What scanners are available for 2001 prius.

My 2001 Prius has 77K. It has done warning lights before and always been a gas cap that was not tightened or a misfire code three times since I bought it last spring. It has been driven very little when I was rear-ended and my Camry was totaled. It coughed a little when I started it, but had no problem driving the first 40 miles. I stopped for about 5 minutes to stretch. When I tried to start it to continue to work, all the warning lights came on and it died. I tightened the gas cap and restarted the car to have it die 2 more times. Third time it stayed on and I was planning on limping two blocks to AutoZone to have the codes read, when it rolled to a stop. No forward, no reverse. By the time the tow arrived, it would go forward. The codes were P3101 and 12689.
