So my check engine light had been on intermittently for the past few weeks. I thought it was for the oil change as it was about that time and ignored it.
View 5 Replies2005 Prius shows a C1241 code, which can mean abnormally high or low positive voltage in the auxiliary battery. In my case it appears to be abnormally high, because my voltmeter showed the battery charged to 18 volts with the car off, and when running it showed 20 volts going to the battery. There's also a POA80 code (hybrid battery pack) but I'm not convinced yet that it's a hybrid battery problem. What would cause the overcharging of the auxiliary battery?
View 8 RepliesI turned on my car this morning to find myself faced with a variety of colored lights, including a little red car on a black bar on my MFD. Drove straight to the dealer and received word that the car was throwing codes P0A80 and P3023 and they recommend replacing the hybrid battery. I have a 2006, have done all the recommended maintenance at the dealer and it has about 133,000 miles on it.
View 19 RepliesMy wife suddenly had error messages today, Check AWD System, check engine, traction. Carista reports P0138 O2 sensor high circuit voltage bank 1 sensor 2and also C1241 ABS low battery positive voltage. I get the O2 sensor or wires could be bad, but the C1241 could be expensive ECU. Think both could happen at same time or just a thrown code? Reset turned warnings off but Carista reports permanent for P0138.
View 5 RepliesI have a 2004 prius that had a HV batyery problem. HV battery was rebuilt. After that car started ran but after shut down it will not start. It will only show red triangle, abs, vcs, yellow tire. Basically all yellow lights on dash board except check engine. Also on the MFD it shows the red car with exclamation symbol. I scanned it but shows no DTC codes.
View 16 RepliesI just replaced my 12V battery and now the car won't start. It will take a jump and show "ready" on the dash but as soon as the car is turned off, it won't start again - no lights, nothing. I checked some fuses and they looked fine.
View 11 RepliesGot these bad codes yesterday on my 2007. Toyota service said the car needs total hybrid replacement for about $3,300. The car has 188K on it. Does this sound right?
View 12 RepliesMy 12v battery died, I tried recharging it etc, but it was dead so I took it to my local Toyota dealer and had the battery replaced.
Because I had the battery off, there was a VSC warning light, which I thought that the Toyota dealer could reset. They re-calibrated all the warning apart from one, they say that the Yaw sensor will not clear it's warning and needs to be replaced.
if I can reset this warning myself, or do I really need to replace this sensor?
I'm getting the 14 blink code on my Hymotion LED indicating that my 12v battery is needing replacement. My question is that the car seems to run fine with the exception of my mileage is low. I'm ordering the Optima replacement. Can I still drive around for another week without worry?
View 2 Replies2005 Prius, 90k, original battery I think, started beeping on shutdown, then wouldn't start today (cold). Got a new battery, but the back hatch wouldn't open, so I tried to jump it following owner's manual instructions. Headlights came on at first (although stalk switch was off), but doors/car wouldn't respond. Disconnected and reconnected jumpers, lights off this time, still no response when trying doors or starting car.
View 7 RepliesI have an 05 Prius which had no significant problems until the HV battery died this past Feb. Two days later, I'm on the highway and lose power, manage to get the car to an off ramp. Have it towed to a dealer where the power failure pulled up code DTC P3190 and I was told that the car was simply car out of gas. The car was at 3 pips without any indicator going off but after consulting this forum I thought "Okay, maybe this is just the new normal." Filled my car with 5 gallons worth of gas which topped it off (?) and went on my way.
I'll add here for lack of a better place that with the new battery the car has not ever seemed to accelerate cleanly - always feels like there's some resistance on the accelerator when trying to go above 50 on the highway.
Cut to yesterday - I lost power on the highway 3 miles from home with the car at 7 pips (!). I had only put 130 miles on the car since last filling the tank so I can *not* imagine this is a fuel issue. And, worse than ever before, this time when the engine failed I had only about 1000 feet to get over to the shoulder. I did manage to get over safely (for those in SoCal, this was on the 5 North and I narrowly missed blocking the ramps to the 134). To make matters even worse it rush hour in 95+ heat, and I was pinned in my car for 20 minutes (traffic on one side, retaining wall on the other) until the tow truck arrived. I cannot have this happen again.
I had the car towed to the dealer this morning. When the car was picked up the car was at 7 pips in my driveway. The dealer states when the car was dropped of there it was at 1 pip, and sent me a picture of the odometer to verify. Wth?!
How is this possible? How could the gauge have dropped so rapidly? Is there a legitimate way the fuel indicator could have dropped so much or is the dealer scamming me? And what could be be wrong? The AAA driver this morning said they should have replaced the accessory battery when they replaced the hybrid battery, and perhaps that was the source of the problem?
Well, just replaced my HV battery, hooked everything up (I think) and tried to start it. ALL the caution lights came on and stayed on. This is the code that showed up on the reader. P0AE0. The battery was refurbished and I changed over my Computer module and the contact posts. Everything is tight, and I compared my pre-takedown pics to the post-repair work and it all looks correct.
View 3 RepliesA few weeks ago, I received the triangle light in my 2007 Prius with 125k miles on it. When I took it to the dealer, they said that the hybrid battery needed to be replaced. A new battery was ordered & installed by the dealer, which took a couple weeks as the battery wasn't in stock. When I picked up the Prius this week, within driving it a couple miles, it was apparent the A/C wasn't working. I took it right back to the dealer who said they'd look into it. When the Service sales guy started it again, it made a very strange noise as well, which it never did before. The dealer has come back and said that not only has the A/C Compressor out but the ABS actuator is also failing. They are saying this has nothing to do with the battery replacement but both these items were working fine before having the battery replaced
View 1 RepliesI just replaced two bad modules in my 2006 (125K mile) traction battery. I replaced one other module a year ago successfully. I installed the battery last night and tried to charge it with my Hybrid Automotive charger. The charger would not go into charging mode. So I decided to check the idiot lights on the dash - plug in key and push the power button - every light on the dash lit up and stayed lit. The battery charge indicator in the display on the dash had most of the blue bars filled. I left the power on for several minutes and the engine never started (usually does regardless of state of battery charge for a minute or two when you first power up the Prius).
View 19 RepliesI have a 2005 Prius Gen II with 114,000 miles on it. I was driving last week when it suddenly displayed a Christmas tree of lights that included VSC and the triangle of death....and of course the battery fan kicked into high gear.
Hooked it into a OBD II scanner:
P0A80 "Hybrid battery pack over temperature"
P3019 "battery block 7 becomes weak"
P3000 "DSL solenoid circut low"
P0300 "random misfire detected"
P000A "engine position system performance- bank 1"
Also C1241, C1242, c1249, c1259, c1310, c1357
I went ahead and cleared the codes. The angry lights went away but came back within minutes of driving. The car went into limp mode but I was able to make it home.
My 2007 just came due for an oil change a week ago (Maint Reqd stays on), not that it matters. Yesterday the Red triangle of death, Check Engine, and brake warning lights came on. We drove another 15 minutes (city) without incident. When I turned the car back on the brake warning was off (and has stayed off) but now the Info Display has the red Hybrid System Warning Light also showing, along with Mr. Triangle and Check Engine.
This morning Autozone read out the P0A93 (confirmed) and C1300 (current) codes for me. With the car "Ready", I can see fluid movement in the inverter coolant reservoir (not sure it qualifies as "turbulence") and feel vibration in the line connected to the pump which is humming so quietly. The 12V battery shows 12.5V with the car off and 13.5V with the car on. Does this mean the inverter is still operating? (I read the P0A93 code is supposed to shut it down.)
I did find the ICE coolant reservoir dry and refilled it with SLLC. There looks to be a small leak in the water pump, but I'll deal with that later.
I've decide to replace the engine in a 2005 Prius. For whatever reason it went bad around 110,000 miles. It was making some noise and then went all at once. I don't know the complete maintenance history of the car, but I know it was pretty regular. I also know the car was driven mainly highway miles and on A LOT of dirt roads. So, the oil may have needed more frequent oil changes.
View 19 RepliesMy 2005 Prius was working quite fine until few days ago when the dash lit up with ABS, Check Engine, red triangle, ((!)), and the red car symbol on MFD. Additionally, the hybrid battery fan now comes on once in a while. Mileage on car is 164K; changed the 12v and hybrid batteries at about 153K. Running it through codes scanners, the following codes were read off it:
* B1421 (Solar Circuit malfunction, passenger side. Also, AC malfunction [although on the car, the AC still seems to work fine])
* P3000 (Hybrid control fault, and cruise control error)
*C2318 (Low voltage error-power supply malfunction)
I have checked 12V status using the diagnostic mode this morning and found it to be 12.0V (although 2 days ago when I checked it was 11.8V.)
I have not used the car since as I wouldn't want it park up by the roadside. I'm scarred to think its the hybrid battery again... For now, the car still moves well. What should I check to confirm real cause(s) of all these?
ok scan system for code with Snap On verus and a Launch x431 this is a 2005 with 192k. I can not find any inf codes to lead me in the flow chart that alldata provides. Are their some years that don't provide inf codes. I have check all 3 smi relay and they are getting the command signal to closed the relays but looks like the smi2 will not close at times can this be the cause of poaa6 of the isolation fault. seems to be intermittent sometimes it closes. As far as the poaa6 I did push the start button 1 time to power up with no not "ready" on and waited 90 seconds and the triangle came on and set code. It has a new 12v battery I have take all the buss bars off the hv and clean, not that bad very littler discoloration and corrosion. Test each cell and have 7.78-7.97 in each ,installed 55w light loaded each and none ever drop below 7.65. this my not be the right way but I am learning and trying to figure this out. Have really never worked on the hv side of a prius always the motor side, but this now intrigues me .
View 9 RepliesMy 2005 Prius with 159,000 miles is a daily driver on a 100 mile round trip commute. Since last year, the Prius only does the commute as I now have a delivery vehicle. The car has been mostly trouble free with the exception of hub/bearing replacements, the left drive axle, and routine maintenance. The combination meter fails intermittently in all temperature ranges and is not limited to only cold weather.
Last week the combination meter failed again as I was leaving to replace a HID headlight in a buddy's 05 Prius. The return trip home was the same. Powered the car off and on three times with no change. The next morning, all was back to normal but the engine warning light remained on. This had never happened in the past.
After a week, I brought it down to get the trouble codes read with the OBD II. Results;
C1300: Malfunction in engine control unit caliper front 1
C1253: Hydroboost pump motor relay malfunction caliper front 3
P0456:Evaporative emission control system pressure leak detected - small leak.
I am replacing the coil springs and struts as the left rear coil has recently broken. The plugs and PCV valve have never been changed. I worry that at this point, the threads may very rusted and difficult to remove.
It's been a while. Am loving my 08 Prius that I bought in October but now that things are warming up, I can see a problem with heat generated by the dark dash under that expanse of glass. Do the lighter color dash mats work much.
