Starts fine and then, when its warm, won't fire up

Once you've got it going if its cold it carets on until you switch off and sometimes it just dies after a few minutes of use

Pluged the code reader in and it's showing 0136 code, the O2 sensor apparently according to the Internet

Anyone help?

Trawling the Internet comes up with a possible dirty inlet as well but I don't want to buy a sensor and it not cure the fault so what else could it be?

I'd ask chip or mike but I'm not sure they are clued up on clios as a rule or just the fast ones

Easiest fix is a demolition ball. Had a Clio myself once....worst car ever.

renault dealer?!

(sorry couldnt help myself )

try disconnecting the sensor and see if itll run without it? i know the older zetecs will run fine without it connect, presumably on a preset map stored on the ecu?! worth a try anyway. obviously it throw up a check engine light or whatever if it has one, but if the car will run and drive while hot itll confirm its that which is the problem. i would have sugested coolant temp sensor otherwise, just the obvious one really.

MrC

Could be crank sensor, they break down when the cars hot but fine when cold.

got to get underneath the car to get to the sensor so that's not happening

it's my dad's mates car but seeing as he only lives up the road, guess who gets collared to fix it

it actually won't start now for love nor money so i've given up

Acidburn

Just get the owner to call out one of these home start places, let them diagnose it for free

^ This.

To be honest probably is the best thing to do or calling a Dealership with the fault code and they would be able to tell you what the fault is related to

Greasenuts

Just my modest t'penceworth, if youre saying its now not starting from cold, O2 sensors dont generally kick into action until the engine is warm, because the engine needs a rich mixture when cold. In my experience cant recall a duff O2 sensor ever stopping a car from starting!

As already said, a crank sensor can though. Theyre a piece of piss to fit and cost about a tenner or something from somewhere like euro car parts. Its well worth just chucking one at it!

foreigneRS

there should be no need to just chuck parts at a modern car - they have sophisticated On Board Diagnostics to tell you what is wrong if you have the proper equipment. If it was a faulty crank sensor, surely that fault would be logged?

Greasenuts

You're right in theory mate and I agree with you, but in my 12 years I've found that french shit seems to defy all reason, and everything that college, university and various diagnostic courses have taught me!!
Yes a faulty crank sensor may log a permanent fault code, it may even have logged one in 'pending codes', (detected during last drive) but annoyingly that's not always the case.

a tenner on a crank sensor is a cheap and cheerful fix, if it fixes the fault

that said, it won't fire up now, just cranks over and the fuel pump works so i'll tell him to get one of them and see what happens when he decides i'm available to fit it

I had a clio once and one day it wouldn't start for me after I'd parked up for 5 mins, it ended up being the throttle body. Might get away with cleaning it all out but I had to replace mine.

will be crank sensor they nearly never log a fault code it is on the top of the bell housing held on with two bolts
failing that a gallon of petrol and a box of matches will cure it

Pull off a plug lead and crank the car to check for a spark. if you don't have one then its down to the crank sensor mate. If you do have a spark then i would be looking at the ECU because they sit on the back of the inlet and over time the heat gets to them and they short out chucking codes up that have nothing to do with the problem. Over the last few yrs i have seen this happen alot with the ecu and thats why most just send the car to the crusher.

studabear

I vote crank sensor, or another clio special the engine loom

xr-stu

yeah as said it wont be the lambda if its not starting from cold.

as above check for spark, if there is spark, it sounds daft but have you tried holding the throotle partly open while you crank it. if the ecu sees the tps at say 50% itll attempt to start the car under diffrent parameters i guess you could say, ive had a few cars with weird hot/cold starting faults and this never fails to get them going after a few seconds.

tommytwotanks

yes, but for more enjoyment find a mate and use 2 sledge hammers

trigger-

Or put it round the banger track then the scrapyard where all those French piles of shit belong

MrC

Fuckin hell dojj change the cam/crank sensors, job done finished, unfortunately changing the air filter ain't gonna do it this time

tommytwotanks

the only trouble is that they are known as rubber door Renault's, because the metal stretches

MrC

Stretches Like kosman's sphincter.

touch the crank sensor and see if it starts.have this quite alot when get a non start renault.cranks but wont fire due to the crank sensor building up resistance so ecu cant see a signal for spark.by touching it your grounding it causing resistance to go.
