Prius (2004-09) :: Clicking Noise From Engine When Revs Up
Apr 22, 2013
The spring (or let's call it a few warmer days) has finally came to Ireland and my sensitive ear started to notice rather quiet clicking noise from the engine. The noise gets faster (you'd get more clicks pers second) when the engine revs up.
It is not very obvious, the two mechanics I asked told me that they can't hear anything and instructed me to enjoy the sun - but I definitely can notice when the ICE starts or shuts down just by presence of this clicking noise.
What's strange, when it has been raining for some time I don't hear it anymore, the engine runs very smooth and quiet. It will keep quiet in the roofed parking garage too - so it is not the rain just masking the sound.
It does not matter if the ICE is hot or cold too. I removed the serpentine belt and have run the engines for a moment without water pomp - but the sound is still there... The oil and filter has been recently changed too.
Apart from that the car runs fine. I get slightly below the typical fuel economy (5.9l/100km = 40mpg(us)) but I think it is still OK: I run only short distances (5-10 miles tops) and decided to ignore the pulse'n'glide technique as it kept my focus off the road.

The other night I was going up the mountain and while going it started making a clicking noise..probably from no oil..We had been told from the dealership there was a small leak but nothing to worry about at the moment.We tested it and it wasn't leaking visibly but I guess with it getting cold out the hole got bigger and we didn't notice so all the oil leaked out as we were powering the lil car through the mountains..Needless to say on the cruise down it started shaking i saw some sparks and I think the rod went through my engine block and we broke down. It's completely dead. The car has right around 200,000 miles on it and has always been very well taken care of.I just traded my dad the car about 7 months ago for my 4-runner cause of gas prices..I moved across the country and of course have had NOTHING BUT PROBLEMS since day one.

2006 Explorer with a perplexing issue that I am scratching my head over. When engine revs to around 3000 RPM, there is a click that sounds like it is under the dash, and the ABS, traction control, and airbag lights come on; if the headlights are on, the dash lights around the a/c controls go out, and sometimes (but not every time) the speedometer and odometer drop to zero. Also, the overhead lighting, if on, goes out. The engine does not appear to be affected. After about 1 second, another click, and everything returns to normal. This happens either while driving or if in park and revving engine. Is this possibly a relay tripping? And if so, why is it triggered by 3000 RPMs?

I don't have a Prius with a built-in bluetooth function, so I purchased the Blackberry Bluetooth Stereo Gateway that gives me audio just by plugging in my 3.5mm jack.
Unfortunately, when the car's engine revs up, I get a very high-pitched audio interference noise. This does not happen when I am connected directly into my phone.

I have a 2007 with 87000 miles on it. Over the past two months, it's developed a clicking noise from the rear of the car. At first I thought it was a loose hatch, but it seems to be shutting snugly. It only happens on slight bumps and not on actual potholes. It sounds exactly like the sway bar links on my old volvo would sound when they were going (which was often), but there are no sway bars on the prius. A suspension noise doesn't surprise me after the winter. The other odd thing is that it occasionally disappears completely for a day or two.

I bought a used Certified Prius with 49k miles on it. I noticed when accelerating (and the display shows that I am using the ICE but not so much that it shoots up into the "Power" portion on the far right) that the there is a clicking noise coming from the front passenger side of the car.
It sounds very much like this:
I don't hear it when only the electric motor is running, and I don't hear it when I really punch it and the power meter is completely filled up. Its more when the power meter is in the middle of the display and the ICE kicks in and I am slowly accelerating.

Recently, my 04 accent (97,000 miles on engine and auto trans) has started to develop a rattling or Clanking noise coming from the engine at low RPM's. I flushed the engine and changed the oil and oil filter, thinking it could be due to oil clogging the HLA, But this was a no go. The engine is still making the noise, and I think it is starting to get worse.
The noise only happens when the car is idling at low RPM's. As soon as I rev the engine past 1000-1500 RPM's, the noise stops. The noise is worse when idling in gear, either reverse or drive, however as soon as you accelerate past 1000-1500 RPM, the noise goes away, until you decelerate to low RPM again. I'll try to take a video of it and post a link to it on here tomorrow.

My Prius C II is at a little over 6,000 miles. I've noticed when I'm accelerating from a stop using the electric engine, that at around 11-15mph I hear a clicking noise coming from the left hand (driver) side of the vehicle.
To hear the sound my windows have to be down and my stereo not playing.
Is this clicking sound while accelerating normal? I know there's a clicking sound that happens when I start my car and when my car sits after parking for a second but this clicking noise sounds like its coming from the front left hand side... not inside the cabin.

When I accelerate, particularly between the 50-60 mph range, the engine makes a very subtle, yet definite clicking noise. Mentioned this to the dealer - the car is still under warranty - and of course, they can't replicate the sound..is this common?

I heard a light clicking noise at about 368-400 beats per minute coming from the engine during acceleration. It was hard to pinpoint and see if it went away since I use the engine so infrequently with pulse and glide, but it was definitely there. I believe it went away by the end of the trip, but was present closer to startup each time I drove today. I'll be able to confirm that tomorrow evening after driving more. It seemed to come from the front right of the engine compartment, i.e. from the ICE. It was not present during EV acceleration, glides, braking, or anything else besides ICE on pulse.
Background:
I just changed the oil this past weekend for the first time since buying the car. It was also my first oil change by myself ever, and I'm thus most suspicious of myself. So go ahead and ask the questions that you might feel would be too "stupid" for most people, I don't mind! I do feel confident I did everything right, a friend had shown me before, and I followed directions from PriusChat as well - but you never know.
I used a Toyota filter (90915-YZZF2) and Napa 5w-30 oil, non-synthetic, which I assumed was what the dealer had been using all those years (2007 model year, btw). I checked the dipstick after driving it the other day and the oil came up to just below the top dot as I wanted.
Mileage doesn't seem to be affected, last few days since the change probably low to mid 60 mpgs average over 150 miles. Perhaps this is something that comes up and "goes away" after some more miles?

I have a 2004 explorer that has a clicking/rattling noise in the front of the engine. What i found is that the bottom pulley has a sleeve or ring inside of that pulley that is just floating loosely back and forth. What this is or what it is supposed to be ??? If it is a bad part, what is the best way to fix it ?

I've only started noticing this recently. I have a 2004 W12 with roughly 75k miles. It seems to only happen after the engine warms up, but even then its seemingly randomly. I'll notice a clicking sound coming from the front passenger side of the engine. The sound increases in frequency as I rev the engine. I have no check engine lights and no noticeable loss of power. Its not a radiator fan since the sound is still audible when the hood is open. I'm getting no CAN errors with my generic OBDII scanner (I know its not a VAG-COM but hey).
I've been reading up on the possibility of it being a bad valve lifter. I don't know much about them and was hoping to get some advice here before I go about asking my dealership to diagnose the sound. I found this random article through google vaguely talking about replacing the lifter. The person says its "reasonable and inexpensive".
I also stumbled across this thread here describing what sounds similar. Although the thread provides no closure it seems towards the end people are hinting that the engine needs to be pulled? This is contradictory to the first source I found. My question is, say it was a bad lifter, whats the extent of work required to fix it? The Parts seem to be really cheap if I'm looking at the correct stuff?

The sound emanates approximately from the area of the coolant storage tank (driver's side, behind the front bumper), though I doubt the tank or its pump is the problem. It sounds only when the car is in 'ready' status. I also think it is not one of the relays in the nearby fusebox. There water-pump drive belt is not on that side, so I don't think it's the water pump or its idler pulley. I have posted a ten-second sound recording on YouTube, greatly amplified. (Ignore the video portion.)

I went out in the 9 degree temp this morning to start my car and take off for work. I sat down and hit the power button and some console lights came on. The gear lights were blinking with a square light around each letter (P, D, R, B...) and the pips on the fuel gauge were blinking, beeping during each blink. Also, the green light on the power button was blinking and the little light showing that the key was not in the car was also on but the key was beside me. I turned it off to try it again.
Before I turned it back on, I inserted the key in the slot and hit the power button again and just the Check Engine light came on and everything else was black. There was a slow tempo click-click-click-click... sound coming from under the hood and the Check Engine light was just sitting there. I tried to turn the car off but the power button was not doing anything. All I could do is let the Check Engine light stay on and the click-click-click-click... sound chirp away. I went back out in a couple hours and the battery was dead.
Just seeing if that might mean something specific before I go drop about $200 on a new 12v battery later today.

Sometime the car is fighting to move forwards when I start to depress accelerator pedal and it sounds like "click click CLICK..." the sound changes from lower to louder depending on how I depress accelerator pedal... (like the car is trying to hard to move)...

I have a 2008 Prius with the platinum 7 yr/100K warranty. The brakes are making a creaking/clicking noise when pressed. It only happens when the car is coming to a stop. If you start the car and sit there and press the brake pedal it doesn’t make the noise. Only when the car is in motion and coming to a stop. I took it to the dealer and they said the brake lever/shaft needs to be lubricated. It is only heard on the inside of the vehicle and doesn’t seem to affect the brake performance.
They said it would not be covered under warranty since it was a lubricating job and not a mechanical problem. They said they would have to take apart the whole dash to get to that part to lubricate it. It would be covered only if the part has failed or broken. They called Toyota to approve the fix, but it was denied. It is just annoying to hear the creaking noise every time I come to a stop. I am supposed to pick up the car tomorrow since they are replacing some other items. I asked for a parts diagram of what part needs to be lubricated to see if I can get to it. I have to take part of the dash apart to install my LockPick and XM radio.

I have no codes on screens, engine revs and gas mileage has gone down to 30 mpg from 40s this summer. The toyota service adviser said the poor gas mileage was from running the heater since it is around 20 degrees these days in minnesota. My innova scanner shows no DTC's. But my question is do I need a scanguage II or other scanner to get the battery codes? Am I missing them using the innova scanner? What scanners are available for 2001 prius.

I bought a 2004 excursion 4wd 6.0 EB Excursion a few weeks ago and I noticed it making clicking noises after I shut the engine off yesterday.
Its been throwing codes P0683 and P0404 intermittently. (they clear themselves after a day or so and dont reappear for another three or four days)

I'm getting an audible whine on starting up from the engine that continues low revs / speeds but disappears upwards of 30 mph or so.
It's only audible inside the car and not outside and is definitely not transmission as it still makes the noise when in P or N.
The car drives perfectly normally, no missing or other issues.
