2003 Dodge Caravan I'm going to be showing you guys how to clean out a throttle body my throttle body is right there first thing I wanted to do was I disconnected the negative battery just good practice when you're working on stuff okay first I'm going to do is get access to the throttle body first thing I'm going to remove is this hose here just to give myself some more ground snow call this hose off I'm going to pull pull this one off set that there
00:40
I'm going to go ahead and remove this airbox just to give myself some more room that's only want to see so this these usually just pull right out and this one does too it's I'm gonna go ahead and remove this air cleaner right now I'm just going to take the one off of here that's an 8 millimeter okay pull this off
01:31
now there's a note this is a this house a yup this has a map sensor looks like right here so this is probably an air intake temperature sensor I don't think that's the map sensor so let me take this sensor off look at it there's two wires is probably not it's an air intake okay should be we'll pull this out
02:32
that is a thermistor their air intake little blue thing in the that's not a math that's a that's a thermistor so that's it that's the air intake temperature if I show you guys how nasty this subtle body is holy crap let me just go closer to your close-up show you how disgusting that is nasty nasty okay I'm going to be spraying this up and I'm
03:03
going to clean out my idle air control so I'm going to clean all that stuff out yeah yeah get started I think I'm going to unplug that maybe just unbolt it from the intake and clean it out really good because it's really nasty looks like there's only a couple bolts I'm going to unplug that connector right there for the I AK and probably take these cables
03:41
off there and unbolt one to look like all I see is three right now let's take those off and okay I'm going to pull this back on this and this looks like this comes out pretty easy you just go back over the top these are both released okay unplug this I like here we go what is that clip I just
04:22
son pistols they love these little red red slide clips I hate them okay yeah looks like I just got to take out a couple ten millimeter bolts one down here it's cute you that out just three bolts holding this on and pull this hose off and disconnect so if we got one more
05:44
thing to disconnect this is the throttle position sensor pretty nasty rusty oh okay here I got my throttle body I'll show you a little bit about it here as you can see this thing is just disgusting almost sealed no wonder has a rough idle you can barely even see light through that thing so it's just really dirty
06:25
really carbon fouled around the edges and this here is the throttle cable spring so when you push on the gas pedal it pulls this and right here is the throttle position sensor it has a power and a ground on the outside and the insides and internal wiper changes their resistance which sends a different voltage back to the computer and it lets it it this tells the computer what position the throttle throttle plate set
06:56
this right here is your idle air control it's a this one's a two pin so it's just a solenoid that moves in and out like this and there's a plunger in here this is real nasty in here real dirty I'm going to take this apart and clean all this out this is actually a 220 torch knit I'm going to go ahead and take this out there's something to clean this up real good actually first I'm going to
07:27
lay this out and this is actually just mass airflow cleaner these are sensor safe so you can buy throttle body or come people use brake cleaner personal preference and this is just what I had so this is what I'm going to use right here got a q-tip and some cotton balls I'm gonna try scrub this out or actually I'll use some some even those pliers to something to hold that sucker open so I don't hurt the fingers
08:26
and between the mechs that's even nastier you okay let's scrub this out quite a bit cleaned it up pretty good now I'm going to take apart this idle air control it's a t20 Torx screw you we'll grab a screwdriver pry that thing out it's like stuck in there so gummed up yeah pry it there we go
09:34
coming down now you see how nasty oh yeah look at that crap that's like pieces of carbon look at that see those big pieces of carbon just stuck in there man this thing probably needs to be changed out oh well I'll clean it up but this thing had huge pieces of carbon just stuck in there very disgusting
10:15
you Oh basically the air cleaner goes around here all this all this air is the air that bypasses the throttle plate for idle bottom basically the computer controls this moves this moves this valve in and out depending upon how much air it wants to let basically let's air in through there goes through there and comes out the back and bypasses the throttle plate for idle can make the
11:02
idle speed go up or down depending upon how how much that valve opens or closes so I'm going to prescribe this a little bit in here anyway that's a lot better I really think I probably should replace this just because I'll gummed up and one but I wanted to pop it back in that screw sucked it down a little bit all right I think it's about ready to go back off I've cleaned it up let the best
11:53
I could let me pop this hose back on okay plug in my throttle position sensor steps on that way push that on this one I push this clip back like that push this on so we get all three started you don't know what the talkback is for these I'm just going to Snug them up you I'm just going to put the box back
13:17
these things just are studs sticking up they snap in but this part fits over the actual real intake so this gasket you want to push it down and make sure these clips are tight which they are you way too hard I think it's good now just had to to two studs to line up and then this thing bolts down and gets us slipped on I've got to throw my and take
14:04
clip I'll go and take care temperature it's all red clip snap there should be good okay now I just got to throw my cables back on you I'll just have to throw this hose back off to recap took these cables off here take these hoes off here took this bolt off here pulled the airbox out took off the
15:08
air intake temperature sensor the idle air control idle air control connector throttle position sensor which is right below the oh my below it right there and unplug the vacuum hose pretty much it cleans it all out through back together
