Prius (Gen 1) :: Batteries Replaced - Engine Revving With Triangle
Jan 6, 2015
I have a 2001 Prius and I replaced the modules with Gen II. It ran fine for awhile then the red triangle came back and the ICE would have a high revving sound and the brake warning light would come on. I can make this issue go away but pulling over and turning off the car and turning it on again. I pulled codes 3000 and 3006 and understand the problem may be uneven battery module levels. I have been driving it in an attempt to see the the modules will self level. An earlier dealer diagnosis also recommended a system main relay replacement which I did not do. It drives fine most of the time but maybe once a week the high revving issue comes back.

I successfully replaced the HV battery on my own and it was so easy even this girl to do it! I drove the car about 300 miles when I got the triangle of death warning light again yesterday. I took my 2002 Prius to the dealer to read the codes but how to borrow a scanner (or whatever) from Autozone and do it myself.

So I drive a 2008 and a couple months ago I started getting the Check Engine Light. Codes P1121 & P1116. Found out it was most likely related to a faulty Coolant Control Valve or Electric Water Pump. Since the pump was just recently changed I went ahead and got the valve changed.
The light is still coming and going but now when I go on the expressway that red triangle with the exclamation pops on with a little beep. Only pops on for a couple seconds and keeps coming back until I drive a bit slower.

Replaced batteries in key fob but does not work.small red light comes on on fob so it is getting power. Maybe a reprogram problem or broken fob.

My wife drives a 2005 Solara 4 cylinder 2AZ-FE. Over the past few years, it has been going through batteries about every year and a half. The batteries have all failed on the load test.
So far, I've removed the alternator and taken it in to get it bench tested, tested fine. I had the full charging system check with the machine, starter tested fine, alternator volts were fine, only problem was the CCA load test (for which the battery was replaced under warranty). I tested for parasitic battery drain several times, got some drain for awhile after car is powered off, but it eventually falls to zero. I checked for voltage drop across the wiring, visually inspected the wiring to the starter, alternator, etc. and made sure the ground connections were tight from the battery to the frame and engine. Everything looked good.
The only thing I can come up with is that the most recent battery boiled over a bit at one point in time because there was evidence of acid spillage. Also, once (and only once), my wife noticed her lights flickering while her car was idling for awhile during a cold morning. These two things lead me to think it must be the alternator (voltage regulator), but neither the bench test nor anytime I test it at home reveals any issue.
Maybe it's an intermittent problem from vibration, etc. I just hate to plunk down the cash for a new alternator if that isn't the issue.

Today I had to replace both batteries and now my ABS light is on. Before replacing the batteries I was installing a XM satellite system and my dash face plate was removed to make installation easier. After putting everything back together and connecting the new batteries the light is on. Tomorrow I will see if any codes come up using my Scangauge II otherwise I'll have to go to the parts store to have them pulled.
This is on an 04 Ex, Limited, 4x4, 6.0 PSD......

I have a 2006 Ford F250 Superduty 4x4 6.0L Diesel with an alternator/battery problem. We have charged the batteries (had them tested at auto zone), and replaced the alternator and still cannot get the batteries to keep a charge. I'm not talking a slow drain, with the ignition switch on for less than a minute it drains about 4 amps and the truck dies. We also noticed a trouble code "TBC fault" and discovered that was to do with the trailer brakes. Disconnected the trailer brake system (have been noticing a "check trailer" warning occasionally recently). What could be causing such a massive drain on the batteries?

So my toddler turned on my dome light on Friday and I didn't realize it all weekend. Monday morning the battery was D.E.D. Charged it all day then jumped it and it turns over but no start. Took it to Autozone for a deep charge and test and ended up with a new battery. Installed it and the engine turns over but still won't start. It ran fine on Friday. This car is my commuter and I don't want to spend the money to take it to the shop. Why it won't now start? Could the dead battery have killed something else while it sat in my driveway?

In the last 2 months I've replaced my starter and 2 new batteries. I've tested the alternator and it's fine. What more is there? I'm guessing the FICM is going to crap. If I attach a scangauge 2 to it now would it tell me if that's the problem?

I was heading home last night from work and noticed something odd. It was the first pretty cold night that we have had around 20-25 deg. and I took off from the parking lot like normal.
When I got to the first stop light about a mile down the road I heard what sounded like the engine revving up right when I took my foot off the gas pedal. It did this as I coasted to the stop light. It also did it again at the next stop light just up the street. I thought maybe it was the heater blower, but It really sounded and felt like the engine revving. The car did not accelerate or anything, is this part of the warm up or normal? I also have the lower grill blocked but I don't see how that would make any difference.

I noticed that when I'm stepping on the gas pedal, revving up, when I release the gas pedal I can hear the engine revving up some more instead of slowing down.
When I release the pedal even if the revolution light on the dashboard shows that it is slowly dropping, the engine is still making the noise as if I am stepping on the gas harder for about a second.
Example: I am at a stop, when I start going from 0 to 30 mph, if I release the gas right away that's when I notice this issue.
This doesnt happen when I'm cruising on the same speed and suddenly release the gas.
I wonder if this is an indication the my tranny is having a problem.
I have a 2013 prius C 2...

I'm driving to work this morning and a bunch of warning lights came on. I was going uphill and the car wouldnt accelerate, the engine was revving up and my presses on the gas pedal didnt seem to be doing anything. I had to pull over a couple of times after shutting the car off and letting it cool down. Each time the car would eventually display the loss of power (would not accelerate, and engine seemed to be revving high with no input felt from gas pedal). Shutting off car and turning back on would cause this to go away.

I recently took a long drive, and on 2 occasions, I heard the engine revving up when just simply cruising steadily at 70-80mph with little throttle input. I checked the LCD screen drive-train diagram, and there's no indicated of the engine turning during the revving. The car does not accelerate during the revving. Happens say for 10 - 20 seconds each time. To stop the revving, I simply give it a bit of throttle. I'm not on Cruise Control. Its a strange feeling, and I hope this isn't connected to the runaway Prius syndrome.

I am afraid to drive my car on the highway and if I am damaging my car by driving it I want to make sure I hold the auto care shop that put the wrong size tire on my car responsible.
I have Bridgestone Ecopia EP100 BL tires size 185/65R15 on my 2007 Prius that I got in 2010. Because of a nail in one tire I had to replace one of the tires two days ago. The technician said they did not have the exact same tire any more but he would replace it with something comparable.
The next day I drove 2 hours on the interstate and the slip indicator light kept flashing, it felt like the engine was revving a lot and/or the transmission wouldn't shift when I got to highway speeds, and it was a little scary. My first thought was something with the new tire since I had absolutely no problems before.

My girlfriend has a 2004 Prius with the nav kit and has been having some rather odd issues as of late, of which seemed to have started after she hit an animal. The gas engine in her car seems to be turning on right away when she turns the car on. The engine also sounds quite loud, almost as if it is revving. Her gas mileage has also dropped considerably, from 45-ish down to around 33 mpg. Also, upon stopping, the mileage gauge on her nav screen doesn't immediately go to 99. Instead it sits around in the 40s for a while before jumping up to 99.
Now, she mentioned this to the tech at the dealer when she finally went to get the recall done on her water pump, but the guy said it drove fine and threw no codes. She then took it to another shop who said it threw a P3190 code, but he had never seen this issue and wouldn't know how to fix it.
The only thing I could find while searching around (mainly on this forum) was that it could be a problem with the electric throttle body. The throttle body seems to make sense to me, but she isn't totally convinced. She also has a 200+ mile trip coming up for the holiday season and it would be nice to fix the issue before that.

I bought a new 2014 Prius plug-in base model two weeks ago. No problems until yesterday.
The engine has started revving really loudly on occasion. It's much louder than the normal ICE noise in hybrid mode - 2 or 3x as loud (much louder than our regular Honda Civic engine).
When the revving happens when I'm in EV mode, the EV mode light on left side of dash stays on (but it's clearly not in EV mode). The EV and Eco symbols above the power bar go blank. The MPG won't go above 25 mpg, no matter if I'm not touching the accelerator. Switching from EV to Hybrid mode and back does nothing.
The only way to get it to stop is to stop the car, turn it off, turn it back on, and then it's fine - EV or Hybrid mode, it sounds normal again. I have not tried to drive more than a mile with the noise to see if it goes away. It occurs when:
-If the fan, heat or defrost is on when I turn the car on - turning them off doesn't stop the revving.
-If I switch the fan, heat or defrost on when stopped at a light - turning off doesn't stop it. (But it doesn't happen if I turn heat or defrost on while moving in EV or Hybrid mode.)
-If I switch from EV to Hybrid mode while stopped at a light.
The weather is cooler now and I'm fine with the ICE starting to warm up the engine, the compartment, etc, but the revving noise doesn't seem normal.

Our 2005 Prius with 160,000 miles is displaying warning lights and the gasoline engine is reving at times and not shutting off when the car is at a stop light.
The dealer says it is throwing a P3000 and P0A80 codes. I asked for subcodes, the dealer doesn't know what I am talking about.
The dealer wants to replace the hybrid computer for $900 and if that doesn't fix it they want to replace the hybrid battery for $3500.

After stepping over gas pedal revving up, when I release the gas pedal I can hear the engine revving up some more instead of slowing down.
When I release the pedal, the engine is still making the noise as if I am stepping on the gas harder for about 3 seconds. when this happened, EV mode will be always not available, and gasoline consumption is increased. Getting lower MPG.

2006, 2G, 43000K. This has happened twice now. Both times on an extended trip of 3+ hours in hot weather: Cruising along at about 70 MPH, the engine just quits. RED Triangle; check engine light; and vcs light. Turned everything off. Car would not restart right away, but after waiting 15 minutes or so, the car restarts and runs fine. All warning lights off except check engine light.
Immediately drove to a Toyota dealership where the following codes were found: P0AOF info 204 (Engine failed to start); and P3190 (poor engine power). The Tech checked the EFI relay; checked for oil puddled in intake; and checked for a contaminated MAF sensor. "No problems found"!

I got my oil changed today and thought everything (10 am) was fine with my car. I drove it straight home after the oil change. About 4pm I drove it to work and no problems still. Finally tonight on my way home right as I turned on to my street the car at first seem to hesitate. Slow a bit and I pushed the accelerator. Then suddenly as I pulled in my drive way the engine began to shake as though I was about to stall and the check Engine light came on as well as the big red triangle.
This has happened before. The display being lit up like a christmas tree so but this time the engine shook. I turned the car off, check the oil, which is full and the coolant which is full. The engine has not shook yet ( but I wont leave the car on for a long time to see if it happens again) the Red Triangle has turned off and now only the check engine light remains.
I am going to call Firestone, that is where I got the oil change all I know is that they did a routine check up (unauthorized by me) and told me I needed a new water pump drive belt and tires and a air filter..... So I am hoping they didn't touch something by mistake. I told the man that I would much rather have that done by the dealership.

This Prius is an '04 with 156k and it will only start with a jump box. I went into the display and found the 12 volt battery reading 12.2 volts after sitting for 4 hours. When driving stop and go around town I will get the red triangle of death and vsc lights but NO check engine light comes on. Using a Scangauge it shows no codes, system ready. I look into pending codes and there is nothing. However when I force clear pending codes the triangle goes away.
It's strange there are no codes associated with this fault. I'm thinking to drive it and not force clear the pending codes and maybe a code will show up eventually but I'm not sure.
