Any idea if I can check live data with a cheapo ebay diagnostics machine, Im guessing I would need a more advanced one as found in a garage? thanks

No idea how to go about checking the above mick so I will have to either have to get a new map sensor and try it or find a local specialists Thanks

ok thanks mick looks like i will have to try and find a local garage that has the ability to do this pity your 160 miles away

thats where i found the info to test the map sensor from your previous post engine idling and probing pins a + b gives a reading of 1.6v (should be +4.3v) engine at 3000 rpm and probing pins a + b gives a reading of 0.00 (should be +4.1v) does that seem to point at a dodgy map sensor thanks

pin a = green earth pin b = purple feed to ecu pin c = +5v earth is fine measured ohms at 2k between pin b + c with ignition off and got 0.00 so all good engine idling and probing pins a + b gives a reading of 1.6v (should be +4.3v) engine at 3000 rpm and probing pins a +b gives a reading of...

thanks mick

hi does any body know what the 3 wires on the map sensor are and in what order also what number pins they go to on the ecu plug earth feed supply to ecu thanks

Well I had continued driving the car with the map sensor unplugged, today i received the new map sensor, installed it and cleared the code. As soon as i went to pull away, the exact same problem, tried to drive it to see if it sorted itself out, but no good. So I unplugged the sensor and tried...

Coil pack seems fine at idle when tested, unless the spark is breaking down under load, I have one coming from eBay anyway, so will put it on for peace of mind. My engine management light came on again, my code reader gave the P0105 code again which relates to the map sensor. I've had the...

I just unplugged the wiring and left the actual sensor in the inlet. Ill have another go tonight and see if it drives any better, although it was driving fine on the way to work this morning anyway. There is no consistency to the problem, it just does it when it fancies it. I'm sure the clio...

I'm sure i tried to start the car with the map sensor unplugged the other day and it wouldn't start at all. I shall give it a go again tomorrow though to either confirm it is/isn't the problem. After owning a 106 GTi that developed numerous problems and 'upgrading' to the 172, I'm beginning to...

Hmmm, I have been thinking that it could possibly be a faulty injector, although wouldn't the problem be persistent rather than intermittent, some days the car runs lovely and then the next I have to pull over five or six times on a journey that is no more than four miles. Its really beginning...

My engine management light finally came on, so I hooked the car upto a cheapo eBay diagnostic code reader. It found one code, P0105. This relates to the map sensor, so I bought one from a scrap yard, changed it over and reset the eml. Although the car is alot better to drive, the problem still...

no mate no lights at all

this is from the emissions test co 0.00% co2 14.50% hc 7ppm 02 1.15% NOx 0.00 rpm 2510 rpm lambda 1.06 thanks Mick

Recently my phase 2 172 has developed a nasty problem to the point it is undriveable. It really begins jerking/kangarooing/hesitating at 2000rpm onwards, I have to pull over as it becomes undriveable, I have been lucky to make it home a few times. So far I have changed the coolant temp...

hi people i am still having major hesitation problems with my clio ph2 172 it is very hesitant and holding back or bogging down although there is fuel starvation on acceleration car has had a new crank sensor swapped the temp censor for another, i have had the emissions checked and they are...

Yeah I have heard good things about black hole, think I may try that along with poor boys sealant and their natty's paste wax. What could I use to strip the old wax off before applying the new products?

What products would people recommend for my pearl black 172? The weekend just gone I washed the car with autoglym shampoo, the applied autoglym paint renovator, then autoglym super resin polish topped off with collinite 476 wax. Whilst the car did come up shiny, it wasn't as shiny as my...

I have recently just started to get 23mpg, I normally see 33mpg with ease, I don't have a heavy right foot either! Would this also indicate that the lambda is knackered?

no light on the dash i have a spare lamda sensor i picked up i will give it a try

do you have any lights on the dash

car had been sitting all day so cold it was turning over and you could here it fire up but would not actually run after numerous attempts we wiggled everything under the bonnet and in the fuse box and it started got it home and too te crank sensor off and cleaned it up this morning and this...

I have since replaced the coolant sensor ans the car was fine, well I thought it was. Got back from work today and the same problem, car wouldn't start. Its turning over but not firing. The throttle body is work I can hear it moving when the pedal is pushed, I can smell petrol so i guess the...

Recently my car has been running poor when cold, it is very hesitant between 1750 - 3000rpm. Then the last two days it has struggled to start, well it starts runs for a second or two and then cuts out. If I hold the throttle down a bit to let it warm, it then seems to get up to temperature and...

Mine is also stuck at 56, does anybody know where I could order the part online?

My dad suggested getting one of those too, I suppose it'll be quite handy to have actually. Think I'll order one once I've been paid.

I have a 6cd changer if that's what you mean? Where did you get the connector from please?

Battery has been disconnected but hasn't reset the light. I think I need to get it turned off via diagnostic software?

Is it possible to install an aux lead into my 2001 172 with the standard radio? If possible how would I go about this? Thanks
