Prius (Gen 3) :: Code P0A0D Appeared
Nov 11, 2015
I am a technician and my boss owns a couple of prius taxis.
One of them had the code to replace hybrid battery pack. After checking all the cells and they were all in spec the code came back every single day so he bought a new hybrid battery pack. After installing the new battery pack The car won't go into ready mode with the message check hybrid system.
The code that comes up is P0A0D about the service safety plug. It is plugged in properly pushed all the way to the right and so on. The 120 amp fuse inside of it is good I have tried everything I can think of.We had another 2010 in the shop I tried changing the service safety plug, engine ecu, hv ecu, all to no avail with the same problem.

I just bought a used 2008 Prius. I had my Prius inspected after buying it, and the error code C1378 appeared, which I have discerned refers to the Skid Control ECU.
There is apparently a recall for this part in 2010-2014 models, however as a 2008 I don't think I apply.

I have a 2004 prius that will not start. First let me tell you what we have replaced so far (within a week) inverter pump, thermostat, water pump, battery 12V(brand new from toyota) and the inverter and it seems to be stuck in drive, but we cannot get it started to figure that one out.Code was reading p0A78 and even after changing inverter it still is reading that code is there.

2004 Prius, 149,000 miles. Driving on a highway when suddenly it felt like a headwind was bearing down on me, and a minute later, the red triangle of death and all the other lights came on. Did not totally lose power. Pulled to the shoulder and while waiting for the tow truck, started and turned the car off several times.
After the first few times, the red triangle did not light up, but the check engine icon remained on. The tow truck driver had a very difficult time getting the car into neutral to pull onto the flatbed, and then when he took the car off the truck to park it at the dealership, he said it shifted "hard" into drive.
I don't have a code since I don't own a reader. What this might be? I really, really hope it's not the traction battery needing replacement. I have no training to replace single cells.

I actually just bought a used 2004 Prius with 207,011 miles on it from out of state. I had a car shipped to me by a flatbed trailer. I just got the car the last weekend. However, It has a yellow engine light and a big red triangle with an exclamation mark (!) on a dashboard, and a red car with ! on top left of a display screen.
I drove it to a DMV to get it registered and took it to Pep Boys near my place since I have to get it an emission inspection within 10 days of registration anyways.
They ran a diagnostic test and found 2 current error codes (C2310-open/short in battery circuit & C2318-low voltage error) and 1 history code (P0A80-hybrid battery pack needs replaced), so they didn’t perform the inspection; otherwise, it would have a failed record). They told me that the car has had problems before and the problems are about a hybrid transaxle and a hybrid battery pack. They also told me that I need to visit a Toyota dealer to get them fixed in order to pass the inspection, and they warned me that is going to cost me a large four digit probably . So, they suggested me to just trade it in because it is not worth repairing. They also told me that a dealer who sold me the car probably would have done something to the car, that’s why it didn’t illuminate any warning lights before.
I tried to gather as much information as I could, so I asked the shipper if he noticed any warning lights but he didn’t think so; one thing he noticed was the hybrid battery isn’t charged because the engine started every time he moved the car.
I plan to take a car to another auto shop near my place as well in order to have them double check the issues and give me a repair estimate before taking a long trip to Toyota dealer.

Bunch of warning lights appeared and the dealer said it's code P0a80 and they recommend replacing the battery. I'd like to try to fix this myself and would like to hear your thoughts...
Plan is to check the traction battery for corrosion and use a voltmeter to test the cells and replace if needed. Prius 2004, 158,000.

My car has been experiencing intermittent throttle issues where it will hesitate slightly. Immediately after this hesitation the trac control trio of lights come on. I don't think this is the bearing as there is no wheel noise to accompany this. Also the trac control lights don't remain on when you start the car the next time. If this hesitation occurs when using the cruise the cruise control will be disengaged.
I also scanned the car and pulled a P0341 and P0440 code. (cam sensor and evap). These codes have existed for the last two years long before the throttle hesitation issue has cropped up so I don't think it is related.

Last week I was on a dive trip and my RX remained parked outside for a week. As I was returning home and I was merging on the highway my CEL appeared; I used my scanner and the code was p2195, which I cleared. My RX was driven for about 5 minutes before merging onto the highway.
On my way home I needed to stop for gas, I filled up and them merged onto the highway and the CEL came on again. I used the scanner and the same code p2195- which I cleared.
I completed my drive home, and have only been doing short city driving since then an no CEL's.

Car is a 2000 Passat Wagon 1.8T ATW FWD
I get the P1128 code and Emissions Workshop warning most of the year, then it cycles off in the summer. It went off yesterday, back on today, and I imagine it will go off again for weeks/months as the weather heats up.
Things I've tried so far:
Replaced MAF sensor
Replaced MAF wiring harness
Replaced front 02 sensor
Replaced air filter
Replaced cracked vacuum tubes, at least those accessible from the top. Some of the hidden lengths theoretically could be at issue but a mechanic said they were ok.
What I've not replaced is the secondary air pump. (Mechanic told me it's dry and checks okay.)

I've been getting these 2 codes (P0113 / P0113P <--?) for a few months now. I know what P0113 means but I've never heard of P0113 P?
Ive cleaned the MAF w/ CRC MAF cleaner. Ive swapped out MAFs and I still get the code every week or so. I ordered a new gas cap & gasket but it seems to tighten fine so I dont know.
Is there anything else I can check?
The GX idles fine, even with the CEL light on. No weird noises or anything else wrong that I can see / hear / feel other than the still 11-12 MPG I'm getting.

I picked up a 2015 gs350 f sport in atomic silver / black. I'm excited to pull out of the parking lot and get on the road! Yeah, not so much. As I take a turn onto the road I notice it's very sluggish, like starting off in third gear sluggish. I eventually get up to speed and wander if the floor mat is stuck under the pedal or something, whatever. anything but the car is broken.
I eventually get up to speed. Everything is fine. I don't accelerate hard because the the car only has 12 miles on it. Otherwise it drives like it should. Off the freeway and at a stoplight with an incline. Start to go, same thing. I pull over, turn the ignition off and back on. Car is fine.
So later that night (43 miles on the ODO) CEL and Trac off lights up. Car will not get up over third gear. Make it another 2 miles home and park it. I'm pretty distraught.
Took it to the dealership, don't know what they are but 2 fault codes came up. One for a shift solenoid and another having to do with the torque converter. Under 100 miles on the ODO!
So I'm with a red ES loaner car. Never seen it on a brand new car.

I got this message on the information display when I turned off the car after an hour of drive. I'm guessing it refers to the key getting low on battery but why only after 2 months.

I just tried to start my Prius this morning and nothing happened except a quick flashing red indicator light which looks like a lock symbol. Not sure what's going on.

I went to the dealership today with my '05 displaying a master light ( big red triangle) and "problem " posted on the screen with the green "hybrid system problem" box displaying.
The Prius guy had the car plugged into the computer for over 3 hours. It spat out a page and a half of codes, and then after a time distilled the codes to 4 things: a bad hybrid fan motor, the relay, a blower motor controller, and a bad aux battery. The problem is I replaced the aux battery a year ago. So it makes me doubt the entire diagnosis.

Recently had HV battery replaced by dealer in my 2005 with 129k.
2 days later the 12v went dead. I removed and replaced it, no problem except when I tried to go to my nav the screen said "please install correct map dvd".
I have never had a problem with my nav since buying the car new in 2005. I assume the problem is connected to the loss of 12v power. The player is under the pass seat.

The 12v battery is 3 1/2 years old.
I rebuilt the HV battery in May 2015. I replaced 3 modules and took the pack through 3 charge/discharge cycles using Hybrid Automotive grid charger and simple discharger. I also cleaned the cooling fan.
All was fine for a month or so. Then I got the trouble lights but the obdlink I had wouldn't show the codes. I noticed a decrease in mileage and a slight hesitation upon acceleration from a stop.
I finally got the mini vci and a win xp laptop to find the codes:
P3000
P0A82
C1310
After maybe a week or so, the ICE wouldn't start and, being busy, I parked it for a while. About a month later, I pulled codes:
P0AA6 with detail codes 526 and 613
P3000 with detail code 123
P0A82 with no detail codes but it indicates "hybrid battery pack cooling fan 1 performance/stuck off.
I connected the grid charger and the HV fan engaged, as it should. I cleared codes and took a drive, while monitoring with Techstream. I watched the fan modes climb to 6, during driving and idling, over about a half hour period. Not sure if this means anything, but I've read that people can hear the fan from the driver's seat when it's running at 3 or 4- I forget which. Well, at 3, or maybe 4, I couldn't hear it. Even standing at the rear door, with my ear against the vent. Though, there was ICE and parking lot noise to contend with. Once it got to 6, I could hear it easily.
Battery health, at that time: With fan at 6, temp of batt tb1 through tb3 was 51.6 c, 56.5 c, 50.4 c.
Battery blocks voltage ranged from 16.05 to 16.15. Internal resistance ranged from .024 to .026 ohms.
Out of necessity, I've been driving this car again, for months now. The lights came back and the codes were still P3000 with detail code 123, P0A82 with the addition of C1310. I don't see a detail code in the same place but there is a field that says "detailed freeze DTC 156". I assume this may be a detail or sub code. Nothing has been preventing me from starting the car. But months ago there had been 2 occasions when, after having driven several miles and parked for a short time, then taking the freeway home, the car would idle high going up an overpass. On these occasions, the MFD shows a low SOC with only one purple bar. The first time this happened, it took around 10 miles before the SOC would creep up. The second time, I had it on cruise control and, while ascending a grade, the car jerked violently and acted as if I were flooring and letting off the gas in quick succession, about 4 times. I disengaged cruise control and took hills more slowly. The high idle up the hills backed off as the battery SOC increased. This time the SOC started in increase within a few minutes, as I would expect normally. I imagine that the electric motor was turning off and on, when the car was jerking, due to a low SOC.
These symptoms cleared up in a few days, apart from the hesitation on accelerating from a stop, and I've been driving it ever since. A few weeks ago, I noticed the car had major difficulty accelerating. I'll floor it and it barely moves, taking several seconds longer than it should to get up to speed. The SOC is stuck at 1 purple bar. I got the car home and turned it off. When I turned it back on, the SOC increased very quickly, only once. I now can't replicate that. The SOC simply will not go above one bar.
Another odd thing. When I'm creeping down the road, at say, 25mph, and I let off the throttle, the car just keeps moving as if cruise control is engaged.

2003 Prius. Situation as follows:
Malfunction Indicator Lamp lit on start-up during sub-freezing weather for failure to start (P3191 and P3101 codes loaded). Occurred twice (so far).
Dealer diagnosed as possible fuel pump problem, though fuel pressure nominal and held pressure after engine shut-off.
Independent mechanic (using EG011-03) diagnosed following:
Diagnosis codes: P3191 (engine does not start) and P3101 with information code 205.
Circuit opening relay was fine.
Fuel Pressure was normal (~45 psig) and held after engine shut off.
Coolant temperature - 9 deg C
Engine RPM - 1200
MG1 Torque value - 0
Installed ECU Part Number - 89661-47053, calibration # 14705301, 14705302
EG011-03 decision tree leads to replace Engine Control Module with newer part number.
Took back to dealer, who indicated still possible fuel pump problem (and reluctant to replace ECM).

I recently noticed that my back seat was all wet. It appears water is coming in from the middle of the seat and spreading outward as far as I can tell. The car has been parked outside overnight. All four windows have been rolled up and there is no water in the trunk.
