Technical Engine Failure Warning - Car running sweet?

Charlieboy13 · Jul 23, 2013

Hi All,

I am now the proud owner of a nice red 2004 Punto Sporting 1.4 16v and I have a slight problem.

The car runs lovely but when I turn on the ignition I get an engine failure warning come up on the dash.

I was told it might be the ignition sensor or exhaust sensor so changed them both, this hasn't made any difference.

I'm stumped because the car idles and runs lovely and doesn't misfire or anything?

Do I need to reset the ECU after replacing the sensors? If so, how?!

I'd really appreciate any help!

Charlie.

You just wasted 2x money on sensors.....

parts roulette.....

Anyway, the EML will come on for a multi-tude of reasons
From sensor no response, to sensor reading to high or low, or interferance etc etc
So what is the cause - who knows till you ask what IT thinks might be wrong

Either have a Auto-electrician read the fault code for you
Or download MES (mutli ecu scan) and get a suitable cable
Since your a 1.4 16v you may need the full version over the free edition tho

Look at what the codes are - report back

I've ordered myself a cable so will look in to the fault codes.
Just frustrating as the car looks and runs like a dream!

I'm new to motoring and was hoping there may be a quick fix...!

Really appreciate your help.

It could be something simple as 1 sensor has detected something it shouldnt
or there is a sensor that isn't responding so its running on base programming so you wont know

get the codes - clear - drive see if it detects again

Hi, got a reader and is giving the code P0443. Cleared ot and thought I was in luck but it's back!
Code points to The Evaporative Emissions System (EVAP). Hoping this isn't a biggie....

May be tyhat the solenoid to the charcoal cannister has gone down. Failures are rare, so see if you can snag one from a scrappy. As always, it's worthwhile taking a butchers at the wiring to it and making sure that the connector is clean.

Ziggy122 · Jul 31, 2013

Thats a first on FF is it for the punto for a canister failure?

Anyway
The guide system i use says that it circuit
Which could be the actuator or the wiring

Since most things on the punto are negative triggered
I'd check for 12v
the resistance in the Canister valve
the wiring
Clean the plug if possible

Thanks Ziggy, I'm going to have a good look at the weekend - managed to get a workshop manual on disk from Italy so should make my life a bit easier!

I don't suppose anyone knows where the purge control circuit is located?

I still can't get a manual for my model!

Generally the "important" bit is the solenoid and connector on top of the cannister. Not sure, though, where the cannister is on the Mk2. Maybe inside the passenger side wing? (That's where it is on Seis).

You should be able to snag the wiring diagram -- although colours will possible differ -- from the Seicento Technical Manual (in the Downloads Library).

The DTE Manual for the Mk2 isn't a great thing: you may be better off with the Haynes.

Well 8 months and far too much time we've finally found the problem!
A missing fuse.

So much effort and time and all that's all it was!

So if anyone else has the above error. Check the F11 15amp fuse first!

Ziggy122 · Mar 9, 2014

Hmmm a 2ndhand car and a missing fuse
There is another storey here

Probably a failed Actuator thats chattering after shutdown = flat batteries is a possibility?

Who knows
could have blown and owner didnt bother replacing since it was still driving fine?

as far as i know - its something that collects the fumes from the fuel tank
Which is then ""injected"" into the inlet manifold on cold start up to prevent the hamful fumes going to atmosphere and allowing it to be burnt off instead which is handy

Passive emissions device. Worthy of bin hurl.

? Not sure I understand?

The car has been fine since replacing the fuse (thank God).
MOT is due so will soon see if there are any problems regarding emissions!

hes saying the charcoal system of emissions is pants mate,nothing personnel

Charlieboy13 · Mar 10, 2014

Ahh I see.

Well I appreciate all your comments and help along the way, great little forum with helpful members.

Going to give her a good overhaul the next few weeks and hopefully fly through the MOT......

fingers99 · Mar 10, 2014

Yeah, the car will run fine without it and it's not testable. Only causes issues if it goes tits up and fills up with petrol.............
