Managed to break a sensor -PLEASE HELP!!!

[edewer]

hey all,

bloody wonderful xmas present I managed to give myself this morning. was mucking about under the bonnet and managed to snap a sensor on the left hand side of the inlet plenum! GRRRR

As a result of it breaking, the car, when started idles at 2k, then drops after 5-10secs to a REALLY lumpy idle. only ran it 15-20s max as it sounded terrible!

Hopefully its not an expensive fix, and possibly even something i can plug in the short term?

any help appreciated!

pics are below.

Why were you playing with your car on xmas morning anyway you muppet lol

 

[edewer]

i was gonna paint the inlet as a xmas present!

Map sensor! You need a new one dude! Make sure the piece in the hole doesnt go down the inlet!!! or it will become valve food.

 

[edewer]

SBV - is that an expensive one? how much are we looking at?

I think from memory about £60 to £70 not replaced one for a while!!

BUT, you can get a second hand one?? depends how quickly you neeed it! There will be plenty on cars breaking etc!

we do them 17.50 + 3.50 delivery. Used 3 months warranty.

 

[edewer]

ah thats not too bad i guess!

Joshydee - you have PM

[SBV116]

Excellent! we like a result!!

 

[edewer]

SBV - another quick q for you

on the right hand side of the inlet theres a grey sensor that plugs into one of the 'legs' of the plenum as seen in the diagram below. i have something plugging the hole (some sort of sensor i assume) but no wiring plugged into it? any idea what that is too?

The little grey one with a 90 degree elbow to the plug? There should be a wire going to that!?

Air temp sensor!

Got mine from josh. Those sensors are a pain for snapping. I managed to Borge mine with some superglue so I could at least drive it

 

[SBV116]

lol @ Borge!

 

[172Ben]

Flol. Ment to be bodge Get back to work anyway you. I need new discs!!

 

[SBV116]

I know i know!!! Send us an email, book you in first week in jan?!!?

Yeah, find the end bit and just glue it together?

 

[172Ben]

Monday the 4th would be ideal. Will send an email now

Have managed to remove the inlet plenum um this morning, and slugged any holes on the block. gonna paint the plenum whilst its off, but is there any kind of cleaner i can put through it to make sure that once i've got rid of the remains of the Map Sensor its all clean?

 

[minisuper666]

Wouldnt running it with the air temp unplugged put it in limp mode?? Unless of course the 50+ HP resistor is bridging the connector?

 

[edewer]

Doesn't seem to be in lmp mode no. As far as I know it hasn't been connected since I bought it, but will be having a look in the light tomorrow

Hmmm, wondering if the MAP could be the cause of my issues as the symptoms you describe sound like mine.

Would unplugging the MAP have any effect?

 

[edewer]

well mine went from fine to lumpy as hell when it broke, so yes i'd assume so!

 

[Da]

Thanks, might try replacing mine.

Did you speak to Josh RE: a replacement and does he have them in stock?

Does anyone know - are they 1*2 specific?

 

[edewer]

josh should be sending me one first thing tuesday so yes as far as i know he has them in stock.

just make sure you dont break it when removing it!

 

[Da]

Yeah I was thinking that, looks quite fragile!

Cheers.

 

[edewer]

Should the new map sensor just be plug and play? or am i gonna require a new map put on?

ed

 

[Da]

A MAP sensor will be just plug and play, I've swapped mine around without issue.

How do you mean "require a new map put on"?

 

[edewer]

as in being a 'MAP' sensor it has something to do with the engine mapping on a car, and therefore 'requiring a new one' would mean does the original engine map need to be reloaded.

but your first answer confirmed what i though, so all is well

 

[Da]

MAP is an abbreviation for Manifold Absolute Pressure, the MAP sensor senses the air pressure difference between what's inside the plenum and what's outside in the engine bay.

 

[Andyman]

Its basically a air pressure sensor not the cars fuelling map so yeah interchangeable

 

[vermeeruk]

Defo map sensor. will run like a sack of s**t. Get you wallet out there £100 at renualt.

 

[Nick_P]

Same as the 1.2 16v

 

[edewer]

managed to get one from the kind people at JMS for the sum total of a fiver posted! good times!

 

[cliosportcraig]

Get the wiring sorted for the inlet temp sensor too

 

[Tigger]

When you take these things in/out, is there something you can put on the rubber O-ring to lube/protect it from sticking?

When the AA guy fixed my recent issue he sprayed something on it as the O-ring looked old and dried up.
No idea what it was though :S

 

[sideways danny]

probably just some wd40 equivalent

 

[Tigger]

Not sure, was in a Red plastic bottle-spray (it was dark) lol
