Technical read a few posts on here, just a quick couple of questions
I'm really interested in this thread too as I am having similar problems ... the injection light is on, although the car seems to be running ok, it is definately running hot .. I have just replaced the water pump (which was leaking) but it has made no difference to th erunning temp .. where is the temp sensor that can cause this light to go on? is the lambda sensor easy to fit? and ... where can I get one of these code readers to tell me whats wrong!
thanks very much
thanks very much
i would check your thermostat isnt stuck first
then the temp sensor is next to the right of the throttle body as your looking at the front of the car
the lambda is just before the cat and unbolts and leads to two plugs that unclip

If you injector light is on there there is problem with one of the following engine components:
ECU
Injector(s)
Ignition
Lambda Sensor
The light being on is telling you that the ECU is overfueling/underfueling the car, dependant on the problem, just to keep it running.
The running temp of Cinquecentos is around the 90 mark... this is normal, and when this hot the rad fan will be on/off about every minute or two, this is also normal.
Please don't worry about the temp, you will become accustomed to them running hot, i would be more concenred about the injector light, as your car's not fueling properly, even if it feels ok.
See the rest of this thread of tips on the injector.
Cheers

I've got a universal one in mine and it's fine!
Just make sure you make a good connection! and seal the wires up well when you're done!
adam .. hope I'm joining in not hi-jacking! I think I need the new sensor too, but I would like to find out what other checks to do, and if /where you can buy the tool you talk about which will tell you why the light is on ...

Yes mate... there'll be clear instructions with it, so you shouldn't have any problems at all. Took me all of about 10 mins to swap them, and the difference was unbelievable!!!

John,
Best thing to do mate is follow the advice here.
It's process of elimination, as you genrally can't buy the tool to read the ECU, other than that find an electronic diagnostic centre, although the ECU usually tells you a load of crap when the Lambda sensor has gone!!!
Cheers

seen these, now there are two white wires, does it matter witch way round they go?

No mate, either way is fine!!
As for the heat sheild... that's a bit of an ass!!
This is my original sensor... the two white wire are visible
These are totally interchangeable. If your sensor is an original it will be bosch so it'll look the same!

ok cheers ive ordered a new sensor, apparently its direct fit for less than £50
fingers crossed.
ive refitted the exhaust, i cut some thread off the clamp and pushed the heatshield up a bit, and sealed the join where it was blowing, then blow torched it to set the sealer,
ill leave it overnight now and fingers crossed it wont blow

Good luck mate!
let me know how you get on... although i'm going away for a week on Saturday, so will pick up after then!
just a word of advise for cento owners using blow torches under there cars.
be aware of the petrol tank issues re: leaks and using naked flames underneath
