Prius (2001-03) :: 2002 - CEL Comes On - Reduced Acceleration Capacity
Feb 18, 2015
I have an '02 with 49,000 original miles. No problems until recently.... warning lights appeared --PS , exclamation and check engine light came on, had reduced acceleration capacity, so I pulled over, shut it off and restarted. Lights still on but continued to drive just fine. After about an hour of driving 2 lane highway, made a "rest" stop, turned off then turned on and NO warning lights!
Next time I went to drive the car several days later, lights were on again, did not go away after 20 min. of in-town driving. The only thing I can think of is that I left a dome light on for several hours, a week ago, before the warning lights incident. Maybe depleted the battery, but the car started just fine right after, so I didn't think there was any problem. Until the warning lights appeared recently.
Could the two be related? What does this tell me? Is my battery a culprit? Can it be re-charged if it is low? I live in a rural area where there are no Prius mechanics... would be nice if I could deal with this myself. Not sure if it has the original batteries.

I've had an issue with my 08' for a few weeks after returning from a 1 week vacation with the car sitting on the street in NYC. The symptoms are a noise associated with poor performance of the vehicle. It accelerates slower and requires more RPM. When you take your foot off the accelerator it feels as though there is a brake on or some additional drag somewhere in the front end. It's really evident that it doesn't actually glide, but it decelerates rapidly.

I change my oil in my car myself and I have been doing so for a while. Just today I bought a 5 quart jug of Valvoline Synthetic Blend 5w-20 (on sale) and a Purolator PureOne filter (also on sale, and the first time I've used that particular filter. I changed my oil like I always did and put in 4.5 quarts of oil as stated by my manual, started her up and all is well.
Now, here's my dilemma. I let the car sit for a while as I waxed, and rechecked the oil and its low (a tad bit higher than the lower mark on the dipstick). I feel like my car has a bottomless oil pit. I do not want to add more oil than I need to, however I feel like if I added enough oil to bring it to the upper mark it would take the whole darn 5-quart jug, if not more. Whats going on here?! I've never seemed to notice this before.
By the way, this is for a 2002 Honda Accord 2.3 Liter engine with VTEC.

I bought a used 2008 Sonata GLS with 65K miles 2 years ago. It's been a great car so far. For the first 25K miles that I drove it, it had good pickup and got ~30 MPG for my highway driving. In the last ~5K miles, the fuel mileage has dropped to 25MPG highway and it has some hesitation when accelerating, especially on lower RPM's. I changed the spark plugs with NGK Iridium, but it is still having the issue. What to check?
Some possibilities: ignition coils, sensors, timing belt, etc?

I have a 2002 Chrysler Town & Country FWD with 3.8L V6. Recently, I had an error code of MISFIRE CYL 5. I changed my spark plugs and added some injector cleaner to fuel tank with no results. Then I replaced my ignition coil and the misfire stopped (according to engine computer after reset and smoother engine). While it was misfiring, the gas mileage was reading about 10-11 mpg city. I changed my oil and air filter, switching to all 10w-30 synthetic oil. Since then, my mpg reads around 8 mpg! Before the misfire, I would get 17 mpg in the city.
One other issue that coincides is a 10-12" long thin vacuum hose near the engine snapped and I replaced it with a common rubber hose. The hose I replaced it with was at least twice inside diameter. I think I need to get the reducer/thin hose setup from a dealer. If the vac hose would be reducing my fuel economy by 7 mpg? Or did i screw something else up when changing the oil and coil? The engine seems to be running smoothly and I'm having no noticeable problems aside from paying for a gallon of gas that takes me 8 miles!!

On the Gen III Prius, is the Battery indicator that is displayed on the HSI an actual 0-100% charge indication of the battery?

Why the battery never charges to full capacity in the battery level indicator on the LCD screen? It never goes over 6 bars out of the 8 bars so it only gets to be 3/4 full.

I have a 2013 Five and cannot find the capacity for the car. I carried this load for 130 miles without a problem.
There might have been an inch of travel left in the rear suspension. This was approximately 1,300 pounds, including me.

What is "reasonable" for the loss of capacity of the Prius Plug in battery? Ours started out with a max at 11.7 miles when fully charged. After 6,000 miles and 7 months it is down to 10.0 miles. This seems like an excessive loss to me. I have read the tips for maintaining capacity and we don't do all the them. e.g. we charge out battery asap so it will be ready for the next trip. Our schedule is not fixed enough to determine when the car will be needed next.

Back in 2012 when I first bought my PIP, the battery charge level as indicated by range was 17-18 miles. The energy to fill the battery has been consistently ~2.5-2.7 kwh.
Earlier this year it dropped to about 15 miles. And just recently it's dropped to about 13.5 miles. The weather has gotten cooler in the last few weeks here in SF, so I don't know how much of this is seasonal as I haven't been keeping track that closely.
I expect to see charge capacity loss over time for the main LiON battery and would like to know what to expect and if my PIP is typical. How much further decrease should I expect in the next couple years? Is your PIP doing better or worse than mine?

On page 93 of the Prius PHV Owners Manual, under the heading "Capacity reduction of the hybrid battery (traction battery)" is the following language:
"By observing the following precautions, battery charge decline can be suppressed."
"Avoid driving near the top speed for EV driving ( --P.40)"
To me this says don't drive EV 60 MPH, don't drive EV 55 MPH, maybe 50 MPH is OK is not uphill, probably 45 MPH is OK.
The manual also says "Also, if the hybrid battery (traction battery) capacity reduces, the EV driving range decreases. However, vehicle performance does not significantly become worse."
I wonder if this is a statement that the warranty will not cover capacity decline?

I'm having a problem with my Prius. It pings under acceleration and it sounds like something metallic is rattling. It only happens when I use 87 and 89 oct. I use 91 premium to reduce the ping however, gas prices are rising and I want to go back to 87. There are no warning lights or anything and the ping has been happening for quite some time now.

2005 Santa Fe (88K, 2.7 V6).
For a month or two, after the car got warmed up, I'd hear a whine/hum noise when I slowed to turn or reduced speed. The noise was much more noticeable when the car had been running at least 15-20 minutes, but I did occasionally hear it when the car was somewhat cool still. Never had a problem steering during this time, even with the noise... but I eventually figured out that slowing down and/or turning brought it on. So I took it to a mechanic.
They showed me bubbles coming from the power steering reservoir, and said I needed a new PS pump and pressure hose, along with a flush/new fluid. I paid for all of that.
Next day: The car would become hard to turn when I made a tight turn into a parking spot... again, not a constant thing, but only when turning to park and going slow. The noise APPEARED to be gone, but this new issue worried me so I took it back. They put a different pump on (no charge), thinking the other may have been defective.
Next Day: I hear the whine again on my way home from work. When I get home, I park, leave it running, and pop the hood. There's a fast drip bubbling from beneath the reservoir cap and running down to the pavement. First thing the next morning I return to mechanic. He says the first two pumps were the same brand and both "remanufactured" so he switches to a different brand -- this one brand new, not "remanufactured" -- and installs that one.
A half hour later, I get home. Hearing that same whine/hum, I lift the hood. Fluid is pouring out from beneath the cap in a steady, unbroken stream (not a drip, but a stream). So I took it back to the mechanic (who to his credit, has charged me nothing since the initial new pump installation). What could cause the power steering fluid to gush out from the reservoir cap when the car gets hot? I have a brand new pump and pressure hose. What could cause this condition..

I used to fill up with gas without shutting the car down, because I didn't see a need for it. I would disable the fan on the climate control every time to avoid having the ice come on as I refueled. I figured that because the ice wasn't coming on, I wasn't breaking the law. I've since changed my mind about this, after reading posts here on Prius Chat. I also recently noticed on the last few fillups that it seems like the gas capacity on the bladder has decreased significantly.
I used to be able to refuel the car when it was down to a single flashing pip and put 10.5 gallons in with no problem, and without overfilling. I have always been careful not to overfill. However, it seems like now I can get only 8 gallons in at the most. The capacity has decreased with the colder weather, however I used to be able to get 10 gallons in on a consistent basis without overfilling even during the winter.
Is this reduced bladder capacity a result of damage to the system, or is this normal? I have probably filled the car up about 100 times since I've owned it (odometer is around 50K now) while remaining in the ready mode.
Is there anything I can do to expand the capacity of the bladder back to normal, or will I have to live with this? Although it's annoying, I'm not going to spend the money to replace the fuel tank unless it's truly necessary.

I have a 2010 6.4L turbo diesel. Without a trailer on a mtn incline I have no issues. She will fly up the hill and she is quiet when I'm not pulling the 10,000 Lb trailer. When pulling the trailer, I have a loud howling noise and reduced performance. I had it at the Dealership and I had them check the engine/turbo and they found no problems? I asked if they tested under load and they said yes?? Someone suggested that the "Waste gate valve" was defective.

2 wks ago, my 2001 Prius with 113,500 miles suddenly failed...no power steering, no acceleration, engine seemed to die. I coasted into a parking lot. Dash warning lights were dire...triangle of death, red car w/ !, main battery, power steering. After powering the car off and on 3 times, everything reset and it drove fine. Took it to dealer next day...ICE not getting fuel and 12v reading low. Cleaned throttle, replaced 12V...things ran perfectly over Christmas weekend...over 400 miles driving all types of roads/conditions other than snow. Dealer had said there was a power steering recall...so I took the car the next week for that work.
Car failed within 7 miles...same warning lights but an entirely different feel to the failure...felt like the transmission was bumped into neutral...no acceleration...but retained PS and was able to steer car easily to a pull-off spot as engine(s) didn't die. Restarted w/ no problem...we limped home, having to stop and restart car 2x in 20 miles as the feeling of transmission in neutral returned. Returned car to dealer next day...they say hybrid battery has failed. I can drive the car short distances but every few miles, I must stop and start it...almost like re-booting a computer...so I'm driving it very little. I do not have the codes from the 2nd failure...I was too shaken up to ask...but will get them ASAP.

Need to diagnose a problem with my 2001 Prius. I was driving it on the highway when suddenly the hybrid system warning light and the main battery light, along with the check engine light came on. I pulled over, turned off the car, and turned it back on. The main battery light error cleared but the Hybrid System warning light stayed on as did the check engine light.
I took my car into the dealership and they told me that the 12V battery was probably low at some point but that they didn't find any problems.
The error codes that came up were: C1215, C1241, C1259, C1521, C1522, C1558, and C1559.

She was driving and she turned onto another road this morning and the Prius started making a popping noise which lasted about 30 seconds. She normally averages about 42/43 mpg but it is down to 37 mpg. She said she has noticed since yesterday the Prius did not drive the same (I am assuming she means the power). The Prius is a 2006 with about 105,000 miles on it. Nothing has ever been done to it since we purchased it new in 2006 except oil and tires.

Tonight I was driving my 2010 Type 2 Prius. I had been driving for about 6 miles in 85 degree heat (after the car was parked all day at work) on the freeway at 60mph when the "check hybrid system" warning came on and my speed reduced to about 40. I pulled over and called a tow truck. After I was towed to a dealer about 25 miles away, the car started up without the "check hybrid system" light coming on. However, the check engine light did come on. My car is low mileage with only 31,000 miles on it.

My headlights on my 2006 are hazy and yellow and the light output is reduced. I tried some plastic headlight cleaner stuff but it was clear for like a month, and now it looks even worse than before.
