Hi there,

Stilo 1.6 16V 02 Plate

Since 6 weeks 2 garages can not fix my car even fiat dealer they changed so many parts that im even lost and charge lots of money.

Where i should to start:

All was fine till i left car for about 3 months without driving.

When i tried to start it i couldn't so we fit new battery. Eventlly car started but was dieing streight after, what is spot was that when im keeping my foot on gas pedal it revs okey, then rev should drop to arroud 700 and be still, but insted engine just died. So we went to Fiat they diagnost that MAP sensor need to be changed coz there is a P0105 error. So they fit new one but no changes. They thay said it my be injectors so they fit new one and guess what.. nothing changed. After they gave me bill for...... too much i decide to go to local mechanic not FIat main dealer. He changed Throttle body, spark plugs coil ignition, Lambda after Cat, and guesss what bigger bill and nothing changed.

What else can be wrong to it.

Till now problem is Error showing P0105, revs are playing round between 400 and 1100 rev, sometimes when i try to test driver it P01220 - going to emergency mode wont rev at all and stays on 1100revs.

I got my self FES and ELM327.

Someone said that i could be a fuel pump in tank but i do not want spend any more silly moneys.

P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction

ive seen this fault occur when the valve timing is out.

do have proof the timing belt has ever been touched or replaced? (it should have been AT LEAST ONCE on an 02-reg) what milage has she done Kisza?


Welcome to FF!
 
Hi there milage is an 52K Miles there is nothing said on service history about timing belt. I did not drive on it long before i did put it on side for 3 months i got this car only 4 months.
 
at 52k id be checking the timing, 36,000 is given as a check and replace (if required) interval for the belt. 72,000/5Years is given as a replacement.

are you certain the garages replaced what they did? have you seen the old part off the car? is the parts they told you they replaced actually new?
 
Regarding parts, they never shown me old ones, trhottle does not looks like new, MAP does look like new (shine and clean), sparks, coils, not sure.

Timing Belt i will try to contact last owner and find out about timing belt. Coz u might be right, i know that there is a cam sensor and if its not sync. revs will play on idle.
It's make sens cheers...
 
cam sensor may not pick the fault up iirc theres only a sensor on one cam... if the other cam is out then it wont idle right and will throw the MAP fault.

coil packs will be pretty obvious i would have thought. throttle may not look new cos they may have just cleaned it internally try doing a throttle relearn.

my findings on timing issues stem from here ill go and find the relearn procedure for you now, bear with!
 
ICV Cleaning Guide

MAP Relearn
Deckchair5 said:
...What you can do is tell your ECU to recalibrate the MAP sensor
Disconnect the MAP sensor. Start the engine, turn engine off
Reconnect the MAP, Clear all fault codes
Turn ignition on and wait 10 secs
Turn off ignition so it stores the data in the ECU
Then start the engine and run on tickover until the engine is fully warm
Turn off ignition
Job done...

Throttle Relearn (after checking that its clean)
T14086 said:
1) switch ignition on (DONT START) for one minute
2) switch ignition off one minute
3) start car (DONT TOUCH THROTTLE AT ALL) and let idle until cooling fan cuts in (10-15mins)
4) switch off
5) repeat step 1
6) repeat step 2

Hi there,

Im not sure will this help but i just been doing MAP Learn,
When i done first step => Disonnect MAP and start engine, engine start for secound and stop after 2 sec with plenty of gray smoke on back, so i started it again with MAP off and my foot on pedal adn there was a plenty gray stincky smoke coming off from exhaust.

When i been deleting errors there was two of them not like usual one

P0105 and P0110 whats the other one?? is it alway showing up while MAP sensor is off??

One more thing engine wont run at all if MAP is disconnected
.

If that will help.

Now in process to warm up engine

Done both Relearing steps and nothing, no diffrent revs still playing round, engine cut off after 20 yards.

I looked in to throttle body is clean and shiny- so they must clean it.
 
There was an older thread in which Deckchair5 helped a guy. I remember it had something to do with the 5V line that is shared between the inlet control valve, the MAP sensor and other stuff. It turned out to be a short circuit at the A/C area that made voltage go nuts...
Check the 5V line, the problem is probably there.

Stop spending money - It has to be an electrical problem that can generate all kinds of errors.

Yes it sounds like your problem is with the throttle body or the throttle body connector and wiring from TB to ECU. The P0105 is saying that the amount of air going into the engine doesn't correlate with what the throttle body is saying eg with that amount of throttle then there can't be that amount of air going in to the engine so something doesn't add up and it goes into limp mode to protect the engine as it doesn't know where on earth the throttle position is. It can't hold idle because it can't control the throttle body valve

The P0110 is the air temp sensor within the MAP sensor so that will pop up too along with the P0105 when it is disconnected so that's quite normal. Just clear the codes and do the MAP relearn

You've been horribly ripped off with people just replacing things vaguely related to the fault code rather than putting some thought to it so you need to take stock and find someone who knows what they're doing

So the focus needs to be investigations on the throttle body and the throttle body to ECU wiring and connections

The TB 5v reference line also goes to the air con pressure stat so if you have air con then simply disconnect the pressure stat to eliminate it. It'll give a P0530 - A/C Refrigerant Pressure Sensor Circuit Malfunction but you can reconnect and clear that as soon as you've checked out whether that makes a difference

Hi there Thanks for all adviced. Just got multimeter and elearn, so i will try mesure and do checks my self it is looks easy. Found as well post about Aircon so i will check this all tomorrow.

Will keep U all up to date.

Regards
 
i had this exact problem. looked on here and got inlet control valve cleaned..it had dirt in it,it has been brilliant ever since. i also spent huge amounts of money on map sensors etc. ive had no problems since.

Hi Guys,

Just want to want to share with my experience, eventlly i solved problem.

Like u said i chacked all electrician problems measure 5V checked MAP to ECU, Throttle body to ECU, Cam Sensor to ECU, but according to eLearn for stilos all was fine.

So i took all adviced and i invest in new MAP again - No changes.

Then i went to scrap yard for second hand throttle body 20 quid... cleaned it an fit it.

Done in FES self adaptation and BINGO!!! It start like new car...

Problem Solved thanks for all... .

Mechanics where i was are shi* charge me a lot of money. Sad is that even Fiat garage couldn't solve this problem.


Love this forum :)

surprised fiat didn't pick it up. mind you there's fiat garages and there's FIAT garages. my 2 locals have a godlike knowledge of them and so they should! my nearest fiat garage ain't worth toffee theyre sutton park so cant even really fix renaults let alone anything proper like a fiat!

good news that you got it sorted tho!

Sorry for being thick, but what do you mean "Done in FES self adaptation"? is that just the throttle re-learn procedure?
