My prius has a coolant leak, which look like it's coming from the throttle body. The stealership recommends a new throttle body. The mechanic said he has not seen coolant leak from the throttle body before. Is this the only fix to replace the throttle body?
View 8 RepliesThe inter cooler to throttle body hose and it seems to have coolant all over it.
View 12 RepliesTook off throttle body on 3800 series1 S/C and coolant is leaking from both bottom ports from mounting area on motor. Is this normal ? Intake area into S/C was dry but very much build up. The 2 ports just end at bottom back of throttle body and are sealed by the gasket. Coolant comes out steadily from those 2 holes. Is this an intake problem, gaskets ?

View 1 RepliesI cleaned the MAF in my 2008 (58k miles) with CRC MAF cleaner and cleaned the throttle body as well. There was a small puddle of oil in the intake manifold from the previous owner overfilling oil so I cleaned that up as well.
View 19 RepliesJust purchased one of the members 2006 Prius. It wasn't in good condition and I knew that upfront. The price I paid justified the imperfections on the car. The car has 117k miles and it does burn oil. To the tune of 1 qt every 3000 miles according to the seller. However I believe it burns more than that amount now. I changed the oil and the dipstick reading was slightly below the minimum mark. The engine doesn't sound all that great but seems to run very well.
I was cleaning the throttle body today and noticed there is oil in that area. I looked down the throttle plate (not sure what that's called), and there was a layer of oil on the bottom. I know oil is not suppose to be in that area. What could this be?
The car had a leaking ice water pump and the coolant was a bit low, not sure if it could have overheated before.
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 4 RepliesI have a 2006 Prius. I must admit that I've never been satisfied with the A/C performance, but now I'm even less impressed.
I had the A/C system serviced at an "after market" place as our dealership calls them (about 2 weeks ago). They added just under a half pound of coolant, oil, and UV dye. The system was much improved after the "after market" shop serviced it and stayed that way right up until it stopped cooling. Two days ago, the A/C stopped cooling and I'm in town so I stop by the dealer. They do the same basic checks I did with the same results - checked the fuses-OK, checked the lines and connections with a UV emitter-OK.
They evacuated the system - removing 0.16 pounds of whatever was left in the system - and recharged the system with 1.06 pounds of 134a, etc.
Neither of us could detect a leak, assuming there was actually dye in the system.
There is no problem with the compressor .
They see no other issues with the A/C system, it was just out of coolant.
Where did the coolant go and why is there no visible evidence of a leak?
Aside from monitoring its effectiveness and checking for dye leaks, is there anything else I should check?
Should the sight glass have enough dye exposed to detect inside the system with the UV emitter?
What should I see (or not see) in the sight glass?
Few 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).
A couple years ago noticed the coolant + inverter reservoir was on the low side. Took it to the dealer who pressure tested it and didn't find anything wrong, added a bit, and said good to go. Roughly 55,000 miles.
Today at close to 85,000 miles the coolant in both the radiator tank and the inverter is again touching the "L" mark. They were filled up to the middle/almost topped off after the dealer visit.
Just curious if others have had this issue and/or where to look. I haven't touched the coolant since purchasing at 42,000 miles in 2011.
This is the only issue I've had with this car so far. But it scares me, as coolant loss can be a big deal! Something as small as this isn't as concerning unless it's leaking some place I don't know about, or being consumed in the engine.
I'm sitting at my Toyota dealer where I bought the car 3 weeks ago. My car is in because it needs to have the engine coolant pump replaced due to a leak. Is this a common fix for the gen 2 Prius? Fortunately this is getting covered under warranty.
View 4 RepliesI was changing the engine coolant on my 2005 Prius today. When I went to fill up the tanks, I noticed a small pool of coolant right under the filler pipe. I thought I might have overfilled something, but when I jiggled the filler pipe, I heard an air leak. It looks like there is a bad seal between the filler pipe and the radiator. I also noticed that my coolant recovery tank was empty. I never noticed this before so I don't know if this issue is related.
View 12 RepliesI brought my Prius, 128,000 miles, into the dealer with the check engine light on. Runs fine, and checked the gas cap. Toyota dealer said they need to replace 4 fuel injectors, replace oxygen sensor, and clean the throttle body. Check engine light needs to be off so I can pass emission test.
View 8 RepliesSo while driving yesterday I had a EPC and Check eng light come on and go away shortly after... maybe 1hr of drive time. Any way I took into dealer today to have them scan and they stated it was an issue with my throttle body.
Now as soon as he told me that he also said he can not do any work under warranty on my engine due to Stage 2 software and intake/down&mid pipe...... no big deal as I figured he would say something like that anyway. Should I take it apart and try to get it cleaned..... or what?
Its a 2010, with roughly 21k miles.... Had APR stage 2 for a few months now and this is the first thing that has come up.
So 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.
View 8 RepliesWhen cranking there is no fuel from the throttle body. Dropped the fuel line on both sides of the filter that was replaced last fall and have good flow before and after the filter. If I spray starting fluid down the throttle body it will fire. Switched out the throttle position sensor and idle air control valve to no avail. It used to die after warming up every so often at a stop light but would start right back up, now it just quit and wont start ???

View 4 RepliesI 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?
What Is that little hose for? I can Smell the gasoline whenever i start the car in the morning. It is cracked But i recently heard a z-zzing Under the hood. Is it an expensive hose? What about the hose clamp.. it looks weird.. is its special for that application ? I wanna replace it myself but I don't want to do it wrong and turn my car on fire.
