Hello, first of all excuse me for the bad English. I’m a prius 2 gen – 2007 y. owner. last week after stop at gas station for fuel (that may be only a coincidence), the car start to interrupts at the highway with 80 miles/h. It was very hot. But that happens only at balance speed, when i.m accelerate the engine is not interrupts. After 60 miles the car suddenly died, with red triangle and all others lights. I put the obd and clear code p3190, start it again and after half a mile, while car I shaking died again with p3190 and p0a80. The hv battery is totally empty (175v). Call Roadside assistance and got home with it. Now the next 2-3 days , I change the old fuel with new one. Clean throttle body and maf. Charge hv battery ( which is 2000 miles , after recycling – 3 elements was change, and other was reordered ) with lab psu , every two elements with 17,7 volts / 5 amper – 5 min. HV battery already shows 226 volts. Cleaned all error codes. Now, I push the start button, the car is going to ready mode…. And nothing, all I hear is one – tik sound. It’s trying to start ICE but only – tik … When put it on D, and push gas pedal , the car is moving and red lines on MFD start showing like the ICE is working but it is not. When put in R car moving very hard and shaking and traction is blinking. When I put it at N , and push it , I feel like pushing a car with manual gearbox with gear on 3 or 4 speed. My logic is that electrical motor and gears working properly , but GAS engine is stuck at D and that is reason not to start up and car to work properly. Put it on techstream and look data list at engine and transmission, no electrical errors . The only code is p3000, probably because car is not starting, and p0a80 , probably the same reason. Please help with suggestions . Thanks.
welcome! i don't know much, but i don't think you should get P0A80 with a good battery and P3000 seems to be a bad battery eco is it possible something was not reconnected properly?
But after reassembly i drove the car about 3 months. Today i try it again and in parking mode and ready , after 10 seconds it's trying to fireup engine, but only thing is that the car move 5 inches upside and then back. I think that mg1 motor is blocked to mg2 which is permanently conected to tyres. And if this is not from any ecu, than the transmission is out . Only one thing i don't understand. the clutch who have four springs. What's he doing , and is it possible to doing this by broken springs.
Those codes are telling you that the high voltage traction battery still has a problem. You will need to do a better job replacing individual modules, or better yet, replace all 28 modules from a battery taken from a much newer Prius. The flywheel and transmission input damper assembly smooth the power delivery from the engine. Even if broken springs were present the engine should at least start.
The battery was completely dead from driving the car only on battery power. At 175 volts, the average module was 6.3 volts. That is effectively 100% depleted. If I understand you correctly, you charged the battery pack by doing two modules at a time. 17.7 volts, 5 amps for 5 minutes. here's my opinion and only my opinion.... That is not enough. 5 amps = 5000mAh if charged for one hour. or the equivalent of 83mAh per minute. So you charged each module with 416mAh. That's only 6% charge. You need 10x that to have the battery in a healthy area. Once you have a charged battery, let it try to start the car once. This will test to see if the work you've already performed has cured the "engine not running" problem. If it fails to start, then you need to do more troubleshooting as to why the engine doesn't run (air, fuel and spark, etc)
Well, thanks for the answers. The battery is charging that way, this method is working fine if you have not high voltage charger, that was not the problem. The car is starting today... but with one wheel on the car jack and direct gear. Only that way and the wheel is spinning. ICE is permanently engaged to wheels. Probably the transaxle is blocking something.
You come here seeking advice. If the information you provided about the battery voltage is accurate, then the information I provided to you about your battery is also totally accurate. I didn't say your method of charging the modules would not work. I said you haven't charged them enough. If you try to buy a drink from a machine that costs $1.75, does it work if you only put in $0.10? You've been led, I can't make you drink. 10-4. Good luck with your car.
Your logic and explanation was very accurate. Simply the battery get enough for 5 min. Probably it's not discharge so much. Thanks for the wish. For me the transaxle is out and need for a new one. Probably there is a leak and is out of fluid. I'll make a last try to fill up with ATF and leave it to work for 10-15 min. Read somewhere that this kind of transaxle blocked without oil, but when it fill again start working . Sounds very stupid but i'll take a chance before change it.
