Prius (2004-09) :: At Start Up Immediately Throwing CEL / Red Triangle And Limp Mode?
We are having an intermittent issue with car starting up and immediately throwing a CEL, red triangle and going into limp mode. Shutting off the car and restarting it sometimes resolves the issue. I'd love to be able to pull the logs from the car to see what is causing this issue.
View 11 RepliesPrius C :: Possible To Stay On EV Mode When Driving Over 20 MPH?
I have the Toyota Prius C and was wondering if it was possible to stay on EV mode when driving over 20MPH? I always put on ECO mode. Sometimes EV shows up, but then it disappears? How does that work?

Any additional scenarios that can kick EV mode off? (I have read if the traction motor is above 104 degrees, EV mode is kicked off.)
Could too much (Enginer) power being dumped onto the HV buss (with a fully charged NiMH battery) also kick EB mode off?
Yesterday my NiMH battery was fully charged, all bars greed (don't know SOC because ScanGauge was set to AMPs). Three hours after a lengthy drive on a 70 degree day when I did have difficulty entering EV mode, I started the car, successfully engaged EV mode and the Enginer Kit, was backing out, and the engine immediately started. (No beeps indicating EV mode was turned off.)
My guess would be that after 3 hours of sitting in a shaded and cool garage that the traction motor would not be 104 degrees.
Could too many AMPs going into the PRIUS (not Enginer) DC-to-DC converter with a FULL NiMH battery cause the engine to start to somehow cool the Prius Converter? (It does have a cooling system, right?).
Prius (Gen 3) Fuel :: EV Mode Doesn't Stay On For A Long Time
In a cold weather also noticed the EV mode doesn't stay on for a long time even with a 90% full battery and fully warmed up. The engine starts to kick in randomly.

One of my pet peeves about the Prius Plug-in is that the car won't stay in full electric mode under hard acceleration. Any mods to keep the car in pure electric propulsion?

I have a 2004 Prius, the Red triangle came on intermittently and went off so I changed the 12V battery last night, after changing it the red warning light went off and everything seemed okay. Today while driving, the warning light came back on. I checked the battery voltage via diagnostic mode on the cars computer and the specs are what they should be. I noticed the following error codes in the computer:
01-D5, Sub-code: 190-30-8
01-DC, Sub-code: 190-B7-8
01-DC, Sub-code: 1C6-4D-F
Not sure if these are what is causing the problem.
Prius (2004-09) :: Red Triangle But No CEL - Symbol On GPS?
After driving for 2 or 3 miles my car turns on this red triangle and says "problem" on the GPS. All the threads i have found this is accompanied by a check engine light but mine does not. On the gps there is also a symbol that i looked up in the manual, it says to take the car to a dealer. is there any way to know exactly what this triangle means? There is not CEL tripped, tried 4 code reader and nothing.

View 16 RepliesPrius (2004-09) :: Triangle Show Up And Just Would Not Go Away
My 2006 has about 67,000 miles on it. The other day it began to behave in a very strange way. I had the triangle show up and it just would not go away. I checked all the fluids and they were good. I did notice that there was a new icon I had never seen before. It looked like it was an curved device with a thermometer attached. When I looked it up the suggestion was to go to Toyota right away. So I decided to drive over. As I drove I could hear the fan from the back seat coming on. It was going very fast, so I guessed that the traction battery was overheating. The car would barely drive, no power. Even when I floored it there was very little acceleration.
I got it to the dealer and they gave me a loaner because it the car was recalled due to the accelerator pedal. Later in the day I got a call saying that a couple of ECUs needed to be replaced. The next day I got a call saying the traction battery was bad and would be replaced under the long term warranty. They said I also needed an aux battery. I knew my battery was not charging up to better than 10 1/2 volts dc. They said it would cost $300 installed, so I said I would get back to them.
Camry :: Code P0128 - Thermostat On Standby
I have unfortunately inherited a 2007 Toyota Camry LE at the passing of an uncle. I recently purchased an Innova 3140 b diagnostic scanner which pulled up several codes. One of which keeps popping back.
P0128 refers to (according to innova).
Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature).
I have replaced the coolant temperature sensor but the codes came back after a few days. I cleared it once again and the code reappeared that same day. I have a thermostat on standby ready to install if the fix requires such.
Prius (Gen 2) :: 2004 - Red Triangle Warning Light Came On And Went Away?
The red triangle warning light on our 2004 came on and went away again It has 100k miles If I take it to the dealer can they pull some codes and figure out why it turned on We have to drive the car to 600 miles for the upcoming weekend and I don't want to be stranded on the side of the road The car has 103,000 miles We just replaced the 12v battery so I know that is OK
I also saw the following things to check. Is there anything else we should check?
1 - Are any warning lights on besides the red triangle? For example, the red BRAKE light, the amber ABS and VSC lights, or the amber circular icon?
2 - Did you check the brake fluid level? If low, buy a new container of DOT3 brake fluid and replenish as needed This fluid will dissolve paint, so do not spill it
3 - While you are at it, check the radiator and inverter coolant levels by looking at the translucent reservoirs behind the radiator and next to the inverter If low, fill with Toyota Super Long Life Coolant
Prius (2004-09) :: Brake / Triangle / ABS And VSC Lights Came On
Recently while pulling into the gas station the brake, Triangle !, ABS and VSC lights came on. The dealer reset the error and said my ECU needs replacement at a cost of $1843. The Prius is a 2005 with 147000 miles. No problems since the reset so I am hopefull. I don't recall reading about a lot of others having to have expensive ECU replacements so I wonder how many have had similar problems and replaced their ECU.
View 2 RepliesPrius (2004-09) :: Red Triangle With Message Appeared
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.
Prius (2004-09) :: Low Oil - Red Triangle With Exclamation Point
My Prius has about 145K miles on it and use it on a daily 130 mi round trip commute. Recently, a I got a Red Triangle w/ Exclamation Point and the displayed showed "Problem". I took the car to the dealership and they stated the problem was caused from a low oil level. The dealership changed the oil and I was good to go. 3k miles later, I got the same error and noticed my oil level was low once again. It seems that my Prius is burning oil at rate of 1 quart per 2500 miles driven. What can be causing this? Are there any remedies I can try before changing out the piston rings?
View 19 RepliesPrius (2004-09) :: Red Triangle And Little Car With Exclamation Point On MFD
I am getting the red triangle and the little car with exclimation point on the MFD. Interestingly all of the amber lights are on and the brake light is on BUT the parking brake is not set.
Here is what happened --my hybrid battery died a few weeks ago so I ordered a replacement through Summit Racing (Dorman Battery). The car started and drove but I had to rest codes to keep it alive (just to get it home). Last moved it 3 weeks ago and removed the old battery.
So long story short -- while I was waiting for the new battery I repaired some other issues -- BTW I am not new to this, I have the tools and have done these repairs on conventional cars many times.
1. Leaking axle seals -- replaced L and R seals
2. replaced L and R half axles (drivers side was rough so replaced both)
3. Found drivers side wheel bearing to be rough so replaced L and R hubs
4. Replaced L and R struts and strut mounts.
5. Drained and refilled trans axle with Toyota W (TF) 4 qts
6. Installed new 12v battery (currently producing 13.4v)
7. Replaced rear struts.
8. Replaced L and R front rotors and shoes -- they were off anyway so why not. No loss of fluid!
9. Removed and cleaned most interior parts -- door panels, seats etc...
Installed new HV battery and fired her up to the usual wheezing, whining and clicking sounds. But NO engine -- just the triangle -- problem statement and and the other above issues.
Checked the following -- inverter pump is circulating nicely, though maybe battery electronics -- so I placed the old battery back in (it was started with the old one 3 weeks ago) -- nope same issue so not those electronics. Traced all wires, plugs and connectors related to hybrid system -- all seem to be in place.

View 1 RepliesPrius (2004-09) :: Red Triangle / VSC And ABS Lights Keep Coming On
The battery in the back looks like it got smashed a little. Do you think this is the cause of the lights? It was a small suv so it missed the bumper and went straight into the battery area. Trunk wont latch anymore the it got pushed in.
Is there an electronic box back there that could have caused the lights to come on?
Prius (2004-09) :: 2006 - Red Triangle At 73 MPH In Neutral
I just bought a 2006 Prius about a month ago (57K). I love the car and have been educating myself on all things Prius, This car has also made me change my driving style quite a bit. I am getting around 50 MPG (combined) and very happy about it.
I have been using some of the hypermiling techniques to get the mileage, one of the things I do is to put the car in Neutral (to emulate the Glide portion of the Pulse and Glide) especially when coming down a gradient. I was bit concerned about using the Neutral gear and called Toyota Corporation to get a clarification, The answer I got from Toyota was - there is no technical issue, however they do not recommend this be done for safety reasons.
Prius (2004-09) :: Won't Start - Red Triangle Message
I purchased a 2009 Prius last year in the US and then got stationed in the UK. I had my car shipped Aug/Sept 2013 to the UK. Up until now the car has run great with no problems. Three weeks ago a red triangle with the message "there is a problem with the transmission "p" lock mechanism. Park your car on a flat surface and fully apply the parking break" appeared.
A week later the car wouldn't start. After reading several forums and posts I checked the battery and it was indeed low. It looked like the original battery and was reading 9.3V. I had the car jumped, drove to the local Toyota dealership, and bought a new battery. After installing the new battery the car ran fine with no issues.
Five days ago (Friday) the car wouldn't start in the morning, but all of the lights worked. Then about 3 hours later the car stared and ran fine all day.
