Prius (2004-09) :: Lost Acceleration - Warning Lights And Fault (DTC) Codes
Aug 14, 2010
2008 Prius recently lost acceleration (would only creep along) and soon stopped. Warning lights - red triangle with !, red split car on mid, check engine - came on. About 10 minutes later the car started and allowed my daughter to creep the last 1/4 mile home. DTC's - P0A3F and P2196. Was recently gassed up, so checked gas cap, thinking it may have set the oxygen sensor code. It was loose, tightened it. Pulled the EFI fuse for a couple minutes to reset the codes (not sure it did). Put the smart key back in and warning lights came on again. May have to take to dealer, but would like to have some notion as to what's causing this. Possibly related -- a couple weeks ago the 12V battery got drained overnight. Pulled it and recharged and everything seemed to be running fine.

These warning lights are lit but my code reader (Actron CP9180) shows 'pass' meaning no fault codes. I had a similar thing happen about a year ago Before I had my own reader) and the cause was a faulty speed sensor on one wheel. Since then all 4 hubs have been replaced. Does this sound like the brake module?

My Prius is 07 with 146k in southern California, for two days every morning I took a short trip to a store then when driving back home the prius battery lost bars fast and I lost power with all sorts of warning lights. Then I drive off with no problems for the entire day. I disconnected the aux battery and that reset the Error codes, I checked the inverter pump and works properly, I checked the aux battery and shows 12v when off and 13.9v -14v when on. This happens every morning so I suspect it's the aux battery. 3months ago my dash lights went out and rebooted the car with no problems.

199k on my prius. I'm driving 65 mph and bam! All warning lights come on, PROBLEM, comes up on the mfd, and the mfd had a funky little broken cat symbol light in the top left corner.
I lose engine power and coast to a stop. As I'm coasting the speed display stops showing my speed... even though the rest of the gouges are lit on the display. While parked I realize I have very little 12v battery juice....
With a jumper pack on the front terminals I get the cat home. I ser on the display the my hv battery is stuck at one bar.
At home I charge the 12v battery and get the hv battery fully charged by holding the gas down in drive with foot on the brake. My Toyota mechanic told me to do that. All warning lights go away. I leave a jumper pack on the battery in the rear and take for another test drive. Car is better but still sluggish... Try to get it up to 50 mph and bam! again all warning lights return.
So I get the car to toyota dealer and and my guy reads the codes and tells me every ecu is showing codes abs recommends 12v battery replacement. He clears the codes. So I buy a brand new battery and after installing it all warning lights return on test ride. Car won't do over 50 mph and is def still a mess.....

My company has a fleet of about 20 2007 GL AWD Santa Fe's. A few of them have had a strange problem....AWD, ESC, and check engine lights will turn on and they will lose acceleration of the vehicle. The dealership has said that it is a problem with the electronic throttle. Apparently it has been quite dangerous for some who have been driving at highway speeds and lost acceleration.

Picked up my rx300 on Monday. Got engine and vsc lights on. Tried battery off to reset. Worked for a day then back. Got a code reader and reset. Found a p00016 code? Crankshaft potion/camshaft position bank 1 sensor A correlation ?

I have a 2001 prius jap import. On a trip it beeped and up came the triangle, check engine light and car with !. The car lost all power and the engine stalled when I pulled over. I plugged in my obd2 scanner and no codes except 3000. Took it to our local toyota dealer who confirmed that code. Had the battery swapped out and still it does the same except now no codes. The car has below normal pickup speed and I can hear the engine rev a little but it does not seem to make any difference. Seems all the power comes from the battery. It will stall when all the error lights come on.

A few months back, my wife (2007 Prius) was telling me that she had some stuff going on with it. I found the diagnostic test for the 12 v battery and it failed. So I replaced the 12v and everything was fine until about two weeks ago. Two weeks ago, she got a check engine light. Then she stopped the car and when she fired back up again, the light was extinguished. So, I figured no big deal. Yesterday, she went to leave and the car was lit up like a Christmas tree. So she took my truck to work and left me a note about this. She figured I would drive my garage queen Vette... but I chose to drive the Prius to see if I could figure out some things, which I did.
Here is everything that I noticed thus far:
First, I will start with lights. Brake System Warning light is on, Check engine malfunction indicator is on, Red triangle with exclamation point Master warning light is on, VSC Vehicle stability control system warning light is on. Then on the tv screen panel, the Hybrid system warning light is on. I ran down to O'Reilly's to see what codes it pulled, and this is what I have: C0200 Right VSS, C0205 Left VSS, C1259 Regenerative Malfunction, C1310 Malfunction H/V System, P1121 Coolant flow control, X2 Valve Sensor Circuit stack, P0A80 Replace Hybrid Battery Pack, P3015 Battery Block 5 Becomes Weak, P3016 Battery Block 6 becomes weak, and then a few more repeats.
What I have looked at and what I have noticed/experienced thus far; At the beginning of the day yesterday, when stopped at a light, the engine would turn on and then shut off frequently (approx every 20 seconds). A lot more than normal. As of today, the engine just stays on constantly... even after the battery indicator shows full, it stays running. The battery cooling fan stays running. Sometimes the car lacks power at start out, When slowing down, I tried selecting the "B" as I know that it would normally work as a trans brake and regenerate power, it doesn't seem to be doing that and it seems as though the tranny doesn't know exactly what to do. I checked the 12v battery again through the diagnostic and it says it was at 12.2v so that should be good. I noticed that the battery indicator will show full and then just drop down to one bar and then go back up to full and stay at full for a while. Lastly, I saw the inverter check and I did that by turning the car on (ready on) and I can see the fluid moving around and I can feel it in the tube and the fluid level is good.
It sounds to me as if the ECM/ECU may be bad. Or maybe the HV battery. I was leaning towards the ECM/ECU just because of all of the different fluctuations, but with electrical stuff, it could very well be the battery.

Goes back to the oil place, they throw it on the computer and read a PO101 and PO171 code. "has to do with with the fuel mixture". She goes to work 11 miles and back. This a.m.
1. Check Engine with !

I've been having issues with my beloved 2003 with a little over 130k with warning lights going on and off. I went to O'Reilly's they gave me the codes P3130 and P0303. One of codes states "misfiring on all cylinders," they didn't have a description for the other one.
Dealership won't tell me anything about what the codes mean. The warning lights are an exclamation point inside a triangle, check engine, and what looks like a thermometer in red.
Just got the oil changed a little over a week ago, dealership said they didn't notice any problems. Warning lights came back on last Thursday and just disappeared about an hour ago.

Here is my situation- back in 2014 I had a local mechanic replace my HV battery and 12V battery after the Red Triangle of Death. Well yesterday that triangle reared its ugly head again! (and cruise control stopped working) Since this mechanic has 3 year, 36,000 mile warranty on all parts and labor, I figured this should be covered. I drove my wife's car to work today, then after work drove the Prius over there to find them closed until Friday!
So I had the guys at Advanced Auto read the codes for me and got P3006, C1213, and C1259. I have done extensive reading and researching, much of it on this site on these codes, but my main question is this:
I commute about 20 miles one way, and on certain days my wife commutes 10 to 22 miles the opposite direction. There are 3 days we go opposite ways this week, and at least one that is completely unmanageable without 2 cars.

Have been having cascading problems since installing PIS 10kWh system in April. Early system shutdown, failed BMS boards, then triggering of Prius warning lights. The latter required disconnecting the 12v battery to 'reboot' and cancel them per Robb of PIS. But then, when attempting to do an electrical load test using air con & other accessories, we triggered several yellow warning lights that do no go away with a reboot. Have been told that we need to have a dealer read the codes to troubleshoot.

I have an 04 V6, yesterday it was perfectly fine...last night we had torrential down pours, high winds and standing water... not sure if any of that matters, but this morning I went to take the kids to school and my "BRAKE" light, the ABS light, and the exhaust lights were all on. Took it to a local shop and had them check for codes. They said it was U0121... lost communication with ABS module. What should I do? I drove it a couple of miles back to the house and again earlier this evening to see if anything felt different, but all seems the same.

I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.

My 2008 Prius (111,000 miles) had all the panel alarm lights go on and lost power while I was driving on the freeway. After turning off the vehicle and letting it “rest” for 10 minutes, it restarted with only the red triangle alert light remaining on and was able to drive to my dealer service (about 40 miles) with no incident. The diagnostic code indicates that the inverter has failed, but the technicians are not able to confirm that this is the problem, since the system is now running. I was able to drive it home with no problems or warning lights. As this is a $4,000 part, I would like to know if this is a likely, or even possible, scenario for an inverter failing, or could it be another problem? Note: 3 months ago the auxiliary battery was replaced following the same circumstances.

So I picked up a 337 a little while ago, which I absolutely love, but there are some fault codes I have to deal with. Pretty sure I took care of the ABS hydraulic pump code. The ABS and ASR light came on after driving in some snow, but I found a thread about that, cleaned the fuses and the light is no longer on.
The following are the problems I am experiencing while driving the car:
I am seeming to have a power drop in 1st gear at low rpms. I have never driven a turbo'd car but I don't believe this is just turbo lag. It isn't a quick increase in power, rather a brief decrease, sort of like it's bogging down. I thought it was just me at first, but I have noticed it too many times and my gf even noticed it. I am not sure if this is related, but I thought I would mention it.
On occasion the dash lights will flash off then back on and reset my trip odo and clock. This has been happening more frequently as of late. It normally happens when I turn the lights on, or switch the brights on. The engine has completely turned off once at a stop light. I am currently searching all the codes online and am hoping to find a solution, but I am definitely concerned.
Also the AC/heater controls dials lights are out (just the three dials), and the 12v power outlet is not working. I tried switching the fuse but it isn't that. Thought this might connected. Final bit of info, the instrument cluster had a problem and was replaced by a dealer on November 29th. I don't know much more about it, I bought it right after that was done. Here are the actual fault codes.
Address 01: Engine
Labels: 06A-906-032-AWP.lbl
Part No: 06A 906 032 ML

2009 Mazda 3 Since a nasty cold snap in Northeast, instrument panel has gone crazy. The meter showing RPM's works but 0 on the speedometer- dead. Gauges have been all on for a couple weeks. Just noticed now the power steering is gone. All lights seem to work normally and heat/defrost works. Radio works. Haven't noticed if odometer is working or not.

The aux battery was changed about 9 months ago and the only problem I currently have is the tag lights are not working.

Had these 2 warning lights show up this morning for no reason. What does it mean? Truck drove fine to work. Guess a trip to the service dept is in the future.

When I turned my Prius on today, the following warning lights remained on:
red "BRAKE"
yellow "ABS"
yellow "VSC"
yellow exclamation mark inside a circle inside parentheses.
It drives fine. After driving it a bit I tried turning the car off and back on a few times. The lights still remain on.
