View Full Version : What Sensors are these?

The clio I went to look at last week had a bit of an issue with a few sensors on the cylinder head which didn't have any connectors going to them, and from what I could see the connectors must have been removed from the loom as they were nowhere to be seen.

What I wanted to check was exactly what the sensors were. There were two where I have put a red circle below, which I believe are the CTS and another temp sensor for the dashboard temp gauge?

There was also another sensor with no connector in the area where I have put the yellow circle, but I don't have a clue what that is?

Does anyone have any idea why anyone would have removed the connectors for these from the loom?

Thanks.

the two there are what u say they are mate, but they dont need to be connected cuz the newer stat housing holds them on the clio's. i had 2 of each sensor on my car, hence the two in the red circle have been cut off, cudnt get oem airbox on with em there!

the other one ur on about i have no idea, nothing there on mine as u can see!

red circle mate is the two in the stat housing that are doubled on the side of the head!http://i14.photobucket.com/albums/a330/coopahstar/P11801171.jpg

so there is probably no problem with them not being connected??

At first I thought it was odd but didn't think they had been cut from the loom. It was only later when I got home I thought about the fact that the casing around the loom wiring (the ribbed plastic) had a slit in it and I put two and two together to think that the loom had been cut.

I may have the positioning of the other sensor wrong, but there were definately three there without connectors and the third was in that general area.

i dont think theres any other sensor that ever goes there in any application mate, got a pic?!

dont worry bout tother 2 mate, they dont need to be connected so long as the other 2 i circled are connected correctly. u having running issues?!

Unfortunately I don't have any pics as I forgot to take my camera when I went to see it (this is all to do with a 16v I am thinking of buying). There were definately three though, I couldn't think what the third was for though when I was looking at them.

Thanks for your help mate, clears things up a bit as I thought it would be needing a new loom, hence my other posts about fitting a loom.

nah man if it runs from cold to operating temp and restarts cold and warm with no hiccups or out then all sensors will be connected fine so i wudnt worry! loosing a sensor tends to make the car run crap as the ecu needs all the sensors to know what its doing with fuelling etc!

lol, I thought that would be the case so couldn't understand what was going on with the sensors sitting there without any connectors.

The car started fine despite sitting for two months or so without being started so I was quite surprised to see the sensors unconnected and thought that it maybe gave some sort of standard value for them when disconnected.

Are there no other sensors whatsoever on that side of the head then? maybe I was just imagining a third one, but I can still picture there being 3 in my head :?

am 95% sure that its only got them 2 down there, theres a bunch of sensors on the front for the injectors n the knock sensor and cold start injector but nothin else on the side i can think of, not there neway! neways if it runs and sounds okay it be reet! if the ecu goes into emergency 'get u home' mode u'd know about it cuz it wud overfuel like a bastard n sound dreadful!

That head is from a Ren 19 16v, hence it has the 2 sensors in the head. they are however no redundant becasue u are running the clio thermostat housing. they are just there to block the holes basically!

If they are from the 19 16v head will that mean the car has had a new engine/head at some point in it's life? or do some clios have them as well as standard?

Thats right mate

on the clio its built into the stat

U might find u will have a black bottom end engine and a differant inlet manifold aswell.

Can you post up pictures of the rest of the engine ?

clio's dont have them that im aware of mate

looks like a replacment head or complete engine...can u get a picture of the engine bay ?

Thanks, clears a few tings up. Unfortunately I can't get a pic up as my folks are away on holiday and have taken the camera with them (how selfish ;)).

Is there any way I can check what bottom end it has, as it's now pretty clear it's had a replacement head at least at some point.

What would be the difference with the inlet manifold?

new head i would say.

mines had a 19 16v head on it since i had it then n all! 8)

rest of the engine looks clio tho i think! :P

if its a R19 engine, it will have no plastic cover over the inlet manifold, the block will be black...

Have a look for the engine number.

get around to the passenger side, stick your head towards the rad - look on underneath the inlet manifold (near the throttle body) for the engine build plate. If its still there.

Oh and it might have alod of plastic covers and brakets beneath the exhaust manifold that arent used.

Thanks mate. The inlet manifold didn't have a plastic cover on it so even more to suggest it's a 19 head on it.

What were the engine codes for the 19 16v and the Clio 16v?
What colour is the block on a 16v Clio?

Thanks.

Another quick question about the 19 engine, would it sit any differently in the engine bay to a clio engine? I'm guessing not as to my knowledge they would be identical, including mountings, but I'm not 100% sure.

The reason is that I thought the srut brace on the car I went to see ran almosr directly above the plastic bit that covers the spark plugs on the 16v, but I have seen other pictures today where the strut brace doesn't pass directly above the plugs. It's maybe just my imagination though, really wish I'd got some pics.

the alternator is in a different positioin on the 19, it wont fit in the engine bay unless u fit the clio alternator set-up.

northy

the block will be black mate.

stan
11-04-2006, 13:04
all the blocks are black mate

donsrno1
11-04-2006, 13:14
thanks, just wondered from what you said if the 19 block was a different colour to the clio block.

Any idea on the difference in engine numbers between the 19 and clio?

northy
11-04-2006, 13:57
no. i know F7P should be clio 1.8

stan
11-04-2006, 14:06
F7P will apply to the whole 1.8 16v range...it will be the numbers that follow that determine to what car the engine was fitted. i dont know them sorry!

it doesnt really matter tbh mate, they are the same

mounts are different in 19, u have to use clio mountings on the 19 head to get it to sit in the clio bay, but it will sit the same as the normal valver engine

stan
11-04-2006, 19:24
the mounts arnt technically part of the engine....u would use the clio gear if fitting a 19 lump so its irrelevant to the actual type of engine.
