Prius (2004-09) :: Irregular Behaviour Of The Car - System Malfunction

Problem and background: for PRIUS 2004 Gen 2 , 157000 km, not getting READY to drive.

1.Warning signals on Power ON, red triangle, yellow color engine, brake, ABS, skidding. Also the PARKING BRAKE RED signal (by the side of seat belt warning signal), does not disappear even if I release the foot brake.

2. Gear can move to N and parking P only, can't move to Drive D or Reverse R. No READY symbol,

3. I left the car in that location in open for a month, during heavy rain. But after coming back , the car had no issue and I was driving for 4 days before this issue started.

what I have tried:

1.Have removed the 12 Volt battery terminals and connected back, just to see if the errors disappear. No change. But did not check the battery voltage or suspect it . disconnected and connected the HV service plug.(orange color lever behind rear passenger seat).

2. Have been switching ON and off the car for 1 full day, First day the local Toyota service (non-prius), came to connect to OBD late evening, he switched on the interior lights and left doors open, within 10-15 minutes the lights started dimming. Before he could pull the information, all shutdown and 12V battery down. his measurement at battery without removing any terminal showed 3.6V.

3. The second day took the battery out and charged at local battery service guy for 6 hrs, he say's charged at 3A, the indicator showed green, that means fully charged, his measurement with no load 12V. After connecting to the car myself, checked the voltage at display by putting to diagnostic mode, showed 12 volts (only with display on) with headlight on and pressing brake drops to 11.6volt. IS THAT OK?

4. The third day got the new battery and replaced, showed the same voltage 12/11.6v, but I can't be 100% sure if that is a brand new battery, the box was open, and since the car didn't start, the battery sales person has taken back the new battery in the same box. I connected back the old battery, it was holding the same voltage. SHOULD I still SUSPECT BATTERY?

5. I can make the READY indication blink twice, if I press hard the brake pedal and hold the POWER button few seconds, during this time I can hear CLICKING NOISE behind at HV BATTERY SERVICE PLUG grip? does that say something?

Sonata NF (2006-10) :: Battery Light Flickering For Just A Fraction Of Second At Irregular Intervals

2009 3.3 GLS ... Yesterday my wife told me that the battery light in her Sonata was flickering for just a fraction of a second at a time at irregular intervals. Nothing else was an issue so we didn't think much of it, started fine, no other lights.

She just called me to tell me that on her way into work it started very hard, all the lights on the dash were flashing, the engine was stumbling and wanting to quit, and the radio is no longer working.

It will be several hours until I can get to it to check it out, but my first thought is to check the grounds. I haven't worked on this vehicle in the past so exactly where to look first or any other issues I should look for...

Prius V :: Intermittent Wiper Knob Backwards Behaviour

In all the previous Toyotas I've driven, you'd turn the intermittent wiper knob "up" to slow down the wipers and "down" to speed them up. And this behavior corresponded with the marking on the wiper switch where the marker line would be thicker at the top (which I assumed to mean wider gap in time between wipes) and thinner at the bottom.

However on our Prius v, the behavior seems backwards. While the markings are the same as other Toyota's, you turn the knob "down", toward the thinner part of the marker line to slow down the wiper and "up", toward the thicker part of the marker line" to speed up the wiper.

Is this the correct behavior for the Prius v?

Prius (2004-09) Fuel :: 2005 - Bad MPG - Need A New Battery?

I have a 2005 Prius that I purchased in 2010 as the second owner. When I first got it, I would average 50-65 MPG depending on city vs. interstate (per trip computer). After about a year, I was usually in the 40's. However, in the past 6 months or so, the MPG has dipped drastically. Based on the trip computer, I average about 30 MPG on the interstate and 15-20 MPG in the city. I have read that often times, a dip in MPG signals a need to change the 12V. I tested the 12V, and it's usually around 12.4V after sitting unused for 12+ hours.

More info: -The poor MPG is consistent whether it's 95, 65, or 35 degrees outside.

-Flat terrain (Washington, DC)

-Usually shorter trips of about 20-25 minutes.

-75% city, 25% highway. Highway driving is pretty smooth, little traffic, average of 55 MPH. City driving is incredibly stop and go due to traffic, constant stop signs and red lights, etc., with probably an average of 15 MPH when I'm actually driving.

-No overfilled oil.

-Had an alignment maybe 8 months ago - nothing unusual about the drive or tire wear.

-Goodyear Viva 2 Tire P185/65R15, maybe 15k miles put on them. Tire pressure unknown at the moment.

-I drive like a grandma in D mode.

-I don't warm up the ICE.

-HVAC is off.

-In terms of whether any significant changes occurred around time I noticed the drop: none. I was living in Florida at the time, doing a highway commute of about 2 hours roundtrip every day with a small bit of city driving when the mileage drop occurred. I have since relocated to DC, and the problem is the same.

Prius (2004-09) Fuel :: MPG Change After Battery Replaced

I have a 2005 Prius recently replaced the hybrid battery. Not so happy with it, my mpg b4 was 49-51 mpg, now I only get 40-45 mpg. I notice the car is a little weaker and the ICE rev higher everytime I accelerate.

Prius (2004-09) Fuel :: Any Way To Force ICE To Charge HV Battery?

I got my car about 2 month ago, and i started to understand how she is working ( how the hybrid cars works in general ), in my daily trip, there is about 5 mile flat road, sometimes when I reach this road SOC shows 3 bars only and its not enough for EV that 5 miles road, but if the battery have more than 6 bars i think it will do the job, and if you will ask me why you don't charge it through the car movement, the answer is very simple, because I am gilding the car before getting that flat road, so, is there any why to force the ICE charging the HV battery?

Prius (2004-09) Fuel :: SOC Dropped - Battery Status To One Bar

Today I went to the national car test (passed. but), when the car has been returned to me by the employee of national car test center I noticed one bar on the SOC. This happened for the first time.

Additional notes:

1) recently (about 4 weeks ago) I had to temporarily replace for second hand (20 bucks) 12v small auxiliary battery.

2) recently (withing last four weeks) I noticed high temperature in the boot compartment, I tried to investigate and the ducting leading from the HV battery was really hot, which means that my battery was really hot too.

I tried to explain this to myself that this might be due to HV operating at higher levels due to unknown state of the replaced 12v small aux battery (second hand product).

3) Today I noticed that technician at the test center used some spring assisted bar to press the brake on the car while he tested the car, I recon that maybe he have had powered off the car while doing so, is it possible that this might have contributed to the dropped SOC ?- it's just my guess.

I'm thinking to replace 12v aux battery to brand new battery and then test the operation of the fan and whether the temperature still rise. - is it good idea? Or should I just seek for the testing tool to determine the status of each of the modules?

If so, which testing device can handle this task? I heard from this forum about ELM obd bluetooth adapter. I use android device, would this be okay or should I look for another device perhaps scangauge?

Honda - Accord :: 2004 - Irregular Chomping Tire Wear

My 2004 Honda Accord Coupe has around 80,000 miles on it. Right now i am experiencing "chomping" or irregular wear on my tires. The inside quarter seems to be wearing at a significantly higher rate than the rest of the tire. However the outer edges have a very "wavy" wear to them as well. The right side of the car is much worse than the left side on both the front and rear tires. I do have direcitonal tires so i only rotate them front to back not side to side.

Research says that it is struts but when i asked my Honda technician he said to push down on the front and rear bumpers and if the car levels off within one and a half bounces it’s not the struts. I did that and it leveled off both on the front and rear. They don’t' appear to be leaking or have anything wrong with them.

So that left me thinking it was a balancing issue. I then went and got my tires balanced and the issue hasn't gone away.

Ford 6.0L Power Stroke Diesel :: 2004 F250 - Irregular EOT And ECT Readings

I have a 04 CC F250 6.0. Lately my EOT and ECT have been all over the place the ECT has been fluctuating more than the EOT. For the past 100K miles my deltas have been within the 15 degree range. The ECT will vary up to 25 degrees from the EOT; EOT may be 180 and ECT 155. I purchased a new water temp sensor thinking that was the culprit, but haven't replaced it yet. I am using a scanguageII to monitor engine parameters. I have noticed when starting the truck in the morning the temps seem to be stored from the previous night, ex. ambient temp is 75 and SGII shows 90 then comes down to match the ambient temps. For the past few days I have been noticing the truck runs and starts smoothly until I get up to 50 mph, when cold, then starts to develop a miss until it reaches operating temps. Once reaching operating temp the truck runs smooth. Could the ECT sensor cause this or is there something else going on, missing at hwy speeds until warmed up?

Santa Fe (CM - 2007-12) :: Unnatural Electrical Behaviour / Lights Came On

I have a 2007 Santa Fe GLS 2.7L

I purchased this used over a year ago and have had a lot of good luck with is so far..

But yesterday, I opened my Front passenger door and closed it. Opened the rear driver's side door and closed it, lights came on.

I than got into the drivers seat and proceeded to start the car, I had NO POWER. Not even the little red security light was on.

I was at a loss, I got out of the car and opened the Rear door again and not lights, so I closed it.

Got back into the car and it started right up...

Prius (2004-09) :: 2008 - CEL Came On / Battery Display Shows The Battery Is Green

I tried to turn on my car this morning, but the "Ready" sign didn't go on. The whole display is black. "Check Engine" sign blinked briefly. Battery display shows the battery is "green". Everything else works - cd/radio/bluetooth, etc. As I tried to start it, the screen showed that the engine briefly charged the Prius battery, then it was all quite. I tried to wait and restart a few times, but still the display was all black and no "ready" sign. I WAS able to still move the car, but I didn't chance to drive it out of the garage. I just had it serviced (oil/fluid change). Small battery was replaced in July.

Prius (2010-12) Fuel :: Battery Power Getting Low Mpg

When the shaded area is in the battery half of the ECO bar I would expect to have the mpg be 100. It sometimes shows only 25 mpg. Just purchased a 2010 and learning how to get the best mileage possible.

Prius C Fuel :: EV Mode - Excessive Battery Wear?

I've been using the EV mode - the EV portion of the curve without pushing the EV button - to run around town and to maintain speed once I've accelerated to traffic speed. It really boosts the mpg numbers and I'm able to get 55-60mpg on my 47mi. Roundtrip mostly highway commutes (hills included). Without the running in EV it's probably 42-48mpg.

Prius (Gen 2) Fuel :: 2005 - Expected Mpg With Bad Hybrid Battery?

A friend of mine has a 2005 Prius, and was asking what his mileage would be when the hybrid battery dies. He has about 131k miles on it, and the battery dies out very quick right now. I told him that with a 1.5L engine, he should get at least 40mpg with the hybrid battery being dead.

Prius (Gen 3) Fuel :: Driving In EV Mode Could Harm Battery?

I've been driving a bit different to try and get some more mpg. I will pulse up to about 45 then let off till ev kicks in and keep the bar right at the verge of going into ice. I can usually cruise at 40 mpg doing this on flat roads while only using the battery. Although if I'm able to do this ev mode for a long distance my battery runs down then the ice kicks in even with the bar below the ice line.

I'm still only getting 50-51 indicated mpg this way but much better than the 42mpg I got just driving it... My route has some hill and my tires are no lrr so I'm think that's has some to do with my low mpg.

Question is does driving 40 mph in ev mode till battery runs dead then recharge with ice just to run battery down again coasting with ev do any harm to the battery?

Prius (2004-09) :: Vehicle Low On Fuel Causing ECU To Shut Down Fuel Injectors

I took my 2008 Prius to Jiffy Lube to have oil changed. When driving away, I made it about one block and all warning lights came on: Master Warning, Hybrid System Warning, Brake System Warning, Malfunction, etc. I pulled the car over and stopped. I started the car again, lights still there - drove 2 blocks back to Jiffy Lube and lost momentum about one block away, with pedal to floor, I could drive about 5 miles an hour into the bay. They looked at it for about 30 minutes and claimed I had bird seed that dropped under the air filter.... I said "goodbye" called AAA and had it towed to my dealer. They said it was because air had entered the system due to my being low on fuel. I have never heard of being low on fuel and it causing the car to shut down nor did I ever get a warning of low gas, still on one bar. Each time I restarted the car at Jiffy Lube, it started fine, drove forward or backward, then lost momentum again. Still no warning of being out of gas. The ticket from the dealer states:

"Vehicle low on fuel causing ECU to shut down fuel injectors when engine started to misfire. Found codes P0A0F, P3190 in system. Added 5 gallons of fuel and reset ECU."

Prius (2004-09) Fuel :: 2008 - Sudden Drop In Fuel Economy - Water Leak?

I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).
