Cleaning throttle body on Toyota car
Gary Chan
Hi,
Is anyone know how to clean the throttle body on 92 Toyota Camry V6? I read
the MOTOR magazine on issue Feb 96 and it said that on Toyota's car the
throttle body must be removed. Could anyone give a detailed instruction?
Thanks

Go to Canadian Tire (or any auto store) and buy a can of carburettor
cleaner and follow the instructions on the can. Cost about $3 Can.

My question is not where to buy the spray cleaner. (even a non tech person
know about it.) I want to know if there is any way of cleaning without
removing the throttle body itself and its attachment on a Toyota car.

I realise you want to clean the insideof the throttle body from gum
build up. The stuff I was suggesting is not a spray, its a liquid
that comes in small can that you tip into the carb or the gas tank. It
degums and internally cleans the carburettor. I think it retails under
the name Wynn's Carb cleaner. It does a good job on any vehicle
including Toyotas. Removing and hand cleaning carburettor jets and
orifices is not work for the inexperienced. Special tooling is
normally required.

Hi Gary I got the post at the site but I will cover it here too.
You enquired about a method I specify in EFI how to pages.
Using a rag an spray carb cleaner on and wipe out the throttle body.
Open the throttle plate and be sure to wipe off the back of it.
This is only nesecary if your TPS is mounted under the T/body.
If you use spray it can run down into to TPS and stuff it up in some cases.
If it is on top or on the side just open the plae and spray straight in to clean it.
In cars with NO remote air flow or air mass sensors you can spray the T/body intake directly with
engine running then finish off with a rag and cleaner.
You will need to use a rag to wipe the back of the throttle plate.
Hope you have long fingers it helps.
otherwise remove the T/body.
You may have a tojo or mitsu with dual throttle plates.
That usually needs to come off to get at the back of the throttle plates.
Once it is clean use the spray into the vac ports wilst running to clear the gum out of them.
The vac signaling on the T/body is very important in some for good operation.
Using in tank cleaners will clean all fuel components but the T/body is an air control device so
none will end up there.

You can't use any type of spray on this 92 Toyota!! You cannot spray
anything into the throttle body nor will putting anything into the gas tank
help. Since you have a fuel injection, the gas never even goes into the
throttle body (except for a few seconds at startup from the cold start
valve-not long enough to clean anything though). Plus if you were to take
off the plastic over the throttle to then spray into the throttle, the
engine would die instanty since your airflow sensor or map, or maf sensor
will not function without engine vaccuum.
I think that indeed you would have to take off your throttle body in
order to clean it. However if you wanted to, you could buy that spray stuff,
find some sort of plugged hole in the plastic before the throttle body,
unplug it, and spray in, given that the hole was small enough to not kill
the engine.

The guy is talking about a throttle body. It is a fuel-injected car. The
throttle body, if it doesn't have a throttle-body injector system only sees
air, oil vapor and coolant going through it. Your main interest with the
Toyota port injection system (no injector in throttle body bore but four
attached to manifold near the head) is to get at the throttle plate and
with a toothbrush soaked in carb cleaner, scrub the area around it clean
(especially its seat). Scrub the throttle plate edges and backside well and
remove residue with a cloth. The other portions of the throttlebody won't
see sludge as the PCV hose dumps in a fan pattern below the throttle plate
and downstream of everything else. If you have a throttle body injection
system (injector in the throttle body bore), you may have to remove the
throttle body to adequately clean it as the plate will be difficult to
reach.
You will locate the throttle body by following the intake hose. The
throttle plate can be located by finding where the accelerator cable ends.

The reason to clean the throtle body is that some of the oil vapor from
the PCV system collects behind the throtle plate. If, If you can get you
hand with a rag to wipe this out after you have sprayed cleaner in you
mignt be able to do this. If not it is best to remove it. I do not know
what plastics are used where on your engine but they can be damaged with
cleaners, and may be the sensors as well if not careful. If you have a
surging idle you may need to clean this area . If not Do not worry about
it.
