Unless you're just driving like a crazy fool

#4: Re: 206 drinking petrol and it only a 1.1 plz help Author: Dabamash, Location: The car in frontPosted: Thu Jan 27, 2011 2:07 pm ---- Plenty of people on here will shed some light on it when they find the thread.
I would suggest a faulty sensor, but it doesn't match the poor fuel consumption.
#5: Re: 206 drinking petrol and it only a 1.1 plz help Author: porkie, Location: nottsPosted: Thu Jan 27, 2011 2:09 pm ---- so a faulty sensor wouldnt affect the fuel being used

#7: Re: 206 drinking petrol and it only a 1.1 plz help Author: Dabamash, Location: The car in frontPosted: Thu Jan 27, 2011 2:12 pm ---- Not sure. I don't think the sensors have any influence on the fuel system. I'm useless when it comes to engines though, I know how they work, but that's about it.
#8: Re: 206 drinking petrol and it only a 1.1 plz help Author: DJ-, Location: UKPosted: Thu Jan 27, 2011 2:15 pm ---- You're seem to be referring to the lambda sensors. My knowledge is not the best in this area but I know it takes the readings and I think if its dodgy it could cause your car to overfuel in which case could be using more fuel?

Yeah, lambdas. If the sensor is connected to the fuel system, then that's a good possibility.
Get it fault read and see if they can be a bit more specific.

Lambder, temp or map would cause the fueling to be off

#11: Re: 206 drinking petrol and it only a 1.1 plz help Author: porkie, Location: nottsPosted: Thu Jan 27, 2011 2:23 pm ---- when it was on code reader would it of came up that the sensors were faulty or dont they show up if they are dodgey
the code reader said this when i took the car
CATALYST SYSTEM EFFICIENCY BELOW THRESHOLD (BANK 1) code no p0420
#12: Re: 206 drinking petrol and it only a 1.1 plz help Author: Dabamash, Location: The car in frontPosted: Thu Jan 27, 2011 2:26 pm ---- Downstream lambda probably needs replacing. Same happened to my 1.1.
Don't quote me on that though
#13: Re: 206 drinking petrol and it only a 1.1 plz help Author: porkie, Location: nottsPosted: Thu Jan 27, 2011 2:28 pm ---- i have found a 1.4 breaking near me will sensors from a 206 1.4 fit my 206 1.1
#14: Re: 206 drinking petrol and it only a 1.1 plz help Author: Dabamash, Location: The car in frontPosted: Thu Jan 27, 2011 2:29 pm ---- Probably. I got mine replaced under warranty, so no idea what it costs new.
#15: Re: 206 drinking petrol and it only a 1.1 plz help Author: Addaz, Location: SuffolkPosted: Thu Jan 27, 2011 2:30 pm ---- Mate, £30 to 120miles aint bad
I will get about 80 to 100 proper eco driving (change at 2k) on £15, so it could be the way you drive

Don't forget you drive a shed with 4 downpipes stuck to the bottom
#17: Re: 206 drinking petrol and it only a 1.1 plz help Author: porkie, Location: nottsPosted: Thu Jan 27, 2011 2:34 pm ---- there has to be a problem mate its getting worse i can see petrol needle going down and down and down
#18: Re: 206 drinking petrol and it only a 1.1 plz help Author: Spanerman, Location: Neath, South Wales.Posted: Thu Jan 27, 2011 2:36 pm ---- Petrol is getting quite expensive, so comparing milages to price is misleading.
Also you drive a underpowered sewing machine, which you have to floor to go anywhere at a decent pace.

#19: Re: 206 drinking petrol and it only a 1.1 plz help Author: porkie, Location: nottsPosted: Thu Jan 27, 2011 2:39 pm ---- i think iam going to swop the Lambder sensors to see if that sorts it

#21: Re: 206 drinking petrol and it only a 1.1 plz help Author: Abzynthe, Posted: Thu Jan 27, 2011 3:58 pm ---- 1.1s drink fuel anyway, they can barely move the car as it is
#22: Re: 206 drinking petrol and it only a 1.1 plz help Author: SDK206, Location: Earth, most of the time!!Posted: Thu Jan 27, 2011 4:18 pm ---- yes oxygen sensors do affect fuelling as yours has two, upstream and downstream it has whats called a closed loop system where by the ECU computes the readings and tries to adjust accordingly but if one goes down it will run "safe tables" to prevent much damage from overfuelling IE melting the CAT.
i would have checked by peugeot, generic codes are useful but not always accurate, theirs will be more accurate
hopefully whoever fitted the CAT didnt use exhaust paste upstream, seen that block them before
but as suggested already petrol is expensive, you can calculate MPG on torquecars.co.uk, all you need to know are miles covered, litres of fuel used and cost per litre and see what it says!!
#23: Re: 206 drinking petrol and it only a 1.1 plz help Author: Matt, Posted: Thu Jan 27, 2011 4:36 pm ---- £30 for 120 miles isnt bad really
1.1s are notorious for being greedy
my 1.4 does 100 for £20
also dont forget, £30 now isnt the same as £30 a year ago. petrol prices have gone up alot so your not getting as many litres for your money.

#26: Re: 206 drinking petrol and it only a 1.1 plz help Author: SDK206, Location: Earth, most of the time!!Posted: Thu Jan 27, 2011 5:42 pm ---- im no expert but that would do it i reckon
#27: Re: 206 drinking petrol and it only a 1.1 plz help Author: L18LTM, Location: ScunthorpePosted: Thu Jan 27, 2011 5:46 pm ---- Is the car making a '' popping noise '', can you smell petrol out the exhaust really bad ?, how hot is your car runnning ? if your temp is low, the ecu injects more fule in ?, my mates golf had his temp gauge behind his intercooler, basically blowing ice cold air onto the sensor and injecting fule wich wasn't needed, running to rich =\ im sure somone on here will contradict me ( as per usual ), but give it ago, happened on my old pug (: faulty thermostat
#28: Re: 206 drinking petrol and it only a 1.1 plz help Author: SDK206, Location: Earth, most of the time!!Posted: Thu Jan 27, 2011 5:55 pm ---- no contradiction needed, if the stat is stuck open it will run rich big time and use far more fuel than normal
