I have a 2012 Camnry I4 and want to clean the throttle body.
Is this throtte the type that I can manualy open valve by hand without damage, or does the pedal need to be pushed to open, to prevent computer or throttle timing issues?
I cleaned my throttle body this afternoon.
My car started fairly easily, and I continued with running it to 4k RPM a few times, then took it for a ride. I floored it a few times, as suggested, to clear everything out.
Now, my 2004 J-VIN Camry is running around 1200 RPM, it was at about 650-675 before the cleaning. Is this normal? Do I need to d/c the battery to reset the ECU so the car can re-learn with a clean TB?
I have a 2004 V6 LE with about 135k miles. I cleaned the throttle body two weeks ago, just because I hadn't ever done it. It wasn't too dirty. Before the cleaning, it idled at < 1k revs. Now, when I start the engine cold, it revs at around 1500, sometimes higher. It goes back to normal after the engine warms up to operating temperature.
Also, I hear a very slight high-pitched whining (maybe hissing?) noise when I accelerate. The noise is more prominent when the engine is cold. I checked for vacuum leaks but couldn't find any.
It feels like I'm depressing the gas pedal a little bit when I have it in drive or reverse, and it wants to pull harder than usual. When I bring the car to a stop with light brake pressure, as it drops into first gear, the car gives a slight tug forward, again, as if the gas pedal is depressed. I mention this to show that it's not just an issue with the rpm at startup.
I suspect that the issue lies with the throttle position sensor, which I may have jostled when I moved the throttle valve. The method I used when cleaning was, I first tried opening the valve by hand with the ignition off, but the resistance was much higher than I had anticipated. So I did the key-in method by turning the ignition to ON and putting a brick on the gas pedal. There was a high-pitched whine coming from somewhere in the engine bay when the key was ON, which I had not noticed before; I wonder if that is normal.
This seems to be a rather common issue after cleaning the throttle body cleaning, but there doesn't seem to be any consensus solution besides to wait it out.
2002 Camry XLE.
I cleaned my throttle body today. Since the throttle plate moves by a motor, in order to keep it open, I turned the key to ON and held the gas pedal down by using some weight.
After I put everything back, the idle was high 2000+, then stays at 1300 to 1400 range. I drove about 10 miles and it is still the same. When stopped at a light in drive, the idle is still 1000
Did I mess up the e-throttle or the throttle position sensor? (Since I used a weight to hold the gas pedal down, I am worried now).
2002 V6 Camry 145,000 miles, cleaned throttle body with TBC fluid, now starts runs for a few seconds and dies. In order to open the butterfly in cleaning I turned ign on and propped pedal down. After cleaning the car ran better but idle was high and a little erratic. I disconnected the neg batt for several hours, now it starts, but dies right away. In the cleaning process I had removed the throttle control sensor an reinstalled it. Can't keep it running long enough to adjust it.
View 8 RepliesI decided to take out the throttle body and clean it with throttle body cleaner that I got from autozone, after I put everything back, I started my car and the motor was shaking and smoking a lot out the muffler and just would not be drivable at all. the RPM was just going up and down and hesitating bad. later I took off the spark plugs and they were very much burnt black at the tips and that is probably not normal right? but I replaced them with NGK BKR7E spark plugs and it still gave me the problem.
View 13 RepliesI need to clean my throttle body on my '97 F-150 and it has a label saying not to clean directly. Is it still safe to use TB cleaner and to go ahead and clean it? It needs done but how would I go about it.
View 6 Repliesread a few posts over the years relating to dirty throttle body, but never understood them. At 60000 miles, should this be attempted by the average guy or just leave it alone if it aint broke?
Any pics addressing where is it, what makes it dirty, how to open it, what to clean it with and how often as preventive maintenance?
I cleaned my daughters throttle body on her 2005 prius. Sprayed it down on the vehicle trying to fix my P0505 code and now its idling high. Is there a learn procedure to reset this after service.
View 6 RepliesCar is 2000 Corolla with 60k miles that sometimes has a low idle (sometimes) when driven for the first 15 minutes early morning. Especially when accessories turn on, the RPM drop suddenly to 600 and recovers to 623 then back to 650rpm. After 15 minutes, everything works fine (normal 650 rpm)....my guess is the IAC Valve/throttle body needs cleaning.
What exactly do I need to tell me mechanic? That both the IAC Valve and throttle body needs to be clean? Also, after "cleaning it using a spray"....should he wait till the "spray dissipates"? What happens if it goes inside the engine?
Got told by the dealer I need to replace my Mass Air Flow Sensor...to the tune of $657 dollars. And get a throttle body cleaning.
View 14 RepliesI cleaned the throttle body with CRC throttle body cleaner and now the motor idles at 1000-1300 rpm. Is this normal for a newly cleaned throttle body? How can I bring down the idling rpm?
View 4 RepliesI went to clean my wife's throttle body out with brake cleaner and I think I sprayed too much into the throttle body now the car won't start. It makes a small clicking/grinding noise when I try to start it. What have I done?
View 12 RepliesFew weeks ago.....Prius was showing the P0505 code .... Mechanic, ran diagnostics and determined it was dirty TB. Cleaned TB.....cleared the code (inspected PCV...hoses).
When I initially picked it up it was revving very high....so he hooked it back up to the scanner and did some type of "reset" for the idle (this cleared most some computer settings...back-up beep, radio stations, etc...). Everything ran fine for past 3 weeks...
Just last night..... started running rough again. What I noticed this morning ... Started it up and it ran very rough til the auto shutdown after warmup (no warning lights). Then....when I started driving slowly out of the lot...it ran "rough upon acceleration"...... Then fine at cruising speed. Same behavior at every light....rough acceleration.... fine once up to speed. Just started it up again and same behavior.....(does not die...just very rough).
I bought a 2009 f150 5.4 with 150000 miles on it. I have a slight hesitation from idle so I want to clean the throttle body. I found several for the older f150"s with the horizontal throttle body but this 2009 has a vertical mounted one. I change the air filter and cleaned the MAF but didn't change anything. My wife's ford 500 had this problem and cleaning the throttle body completely cured it.
View 3 RepliesHigh mileage 1999 4.6 4wd 5 spd: Needed to replace the rear ABS sensor and decided to clean the throttle body too while the battery was unplugged. Cleaned it around the butterfly and not much else. Truck idled at 750 BEFORE cleaning the TB. Now it fluctuates between 820 and 950 rpms. Also tends to stay at a higher rpm after pushing in the clutch and taking it out of gear.
Did a thorough check for vacuum leaks, nothing. After research, I cleaned the IAC and re installed (battery was disconnected then too). No improvement. Unplugged the IAC while running- ZERO change in idle. Installed new IAC, no change whatsoever. Unplugged NEW IAC, no change whatsoever. Is there an issue with the PCM needing time to fully re learn? Am I missing something.
Trying to clean the throttle body on my 09 sonata 2.4L due to rough idle occasionally (throwing P0106, replaced MAF sensor still same problem), one quick question, is it okay to force the valve open (with connector disconnected of course), and is "re-learning" necessary and what's the proper way to do it?
View 2 Replies08 Accord. After replacing the starter and cleaning the throttle body I keep having a CEL and the P0507 code.
Checked for leaks around intake, vacuum lines, etc. found none.
Tried the relearn procedure and still no luck. Car idea higher than normal ( just over 1000 rpms warm). Also feels like it wants to pull even when stopped.
So I figure I have either:-damaged the throttle body somehow cleaning it- Have incorrectly implemented the re learn procedure- missed a vacuum leak ( possible but doubtful)- or something else I don't know about
I have a 2015 F250 with a 6.2L and want to clean my throttle body. I have done several before on other vehicles but, just figured I would ask before I just jump in there. Cleaning throttle body on their 6.2L?
View 5 RepliesSo i recently bought a used 2003 camry le 4cyl with 72k miles on it. So it's still in good condition. Previously I had a 92 camry 4cyl which is run with throttle cable. The new generation camry's now are drive by wire or driven electronically. So I decided to check out the whole car and looked into the throttle body, the out side of the butterfly plate, and notice some thick black substance. It seems like grease or oil. I don't know if its there to lubricate the motor to run the plate or just oil.
