Help with Skoda Fabia

[skylineskoda]

Soon after I bough a fabia 1.4 l, 2001 from a friend the engine maintenance light appeared. The friend told me that it had happened to him a few times but always dissapeared after a few days. So it did. But then it reappeared. And the car began stuttering i.e. accelerator would stop responding intermittently and a couple of times it was so bad that I lost acceleration almost completely so I had to pull over. Problem magically solved both times when switched off the engine for a couple of minutes.  

 

So another friend borrowed a computer and we found three fault codes: 

 

i was told that I need to replace accelelerator pedal, O2/lamda centre and camshaft sensor and that the cost would be 360 excluding VAT or around 450 with VAT. 

 

Right now the engine maintenance light is off and the acceleration is working properly so I don't know what to do. Sell it for spare parts, or fix it somehow? I prefer to keep the car because despite it's age it looks good plus I've spent money on it.

 

Can I fix this on my own or should I go to a mechanic and what would be the cost? I don't know much about cars so go easy on me, I will use Google if there is something I don't understand.

Welcome to Briskoda. Ross-Tech's Wiki is a good starting point for information on those 3 fault codes as you will see below. Hopefully one of our members with experience of the 1.4 engine will be along soon to offer advice on the way ahead.

Replacing the cam position sensor is cheap from ECP and very easy for you to do yourself, should take about 5 minutes even if you're hamfisted  :p

 

Edit: Forgot to say, ignore the last one for now, just replace the CPS and clear all the codes.

Welcome to Briskoda.

Nice to be here :-)

 

Forgot to say, ignore the last one for now, just replace the CPS and clear all the codes.

How about the second one(18047), should I ignore that too? And what does erasing the codes do? (sorry limited knowledge) By the way, I live in Brighton as well.

So did any of these codes had anything to do with the 'stuttering" described above? (Gone now, may reappear?) Extremely busy with work until Sunday evening so bare with me

Quite often a singe fault code can through up other spurious codes.

 

Before you buy any parts, I would check the engine management system fuses.

I checked and cleaned the plugs to the computer, didn't solve anything. Two mechanics said the timing belt is faulty (a third one said totally insane things like accelerator pedal replacing), and I got two completely different prices so I am going for the cheaper one, next week, as long as the car doesn't need more money to pass the MOT (mechanic will check first).

Apparently this one has a Skoda engine, not a WV, and there is no camshaft sensor.

If it's the Skoda 8 valve engine there is no timing belt, it's a chain. Also there is a camshaft sensor! (part number 047907601).

 

Cam sensor is right next to the oil filter...

 

[Breezy_Pete]

Cam sensor is item 9 on this page for your AQW engine, part number is 047907601 according to this page.

 

Accelerator pedal problem is entirely plausible with the 18047 code, I'd've thought. There's a pair of potentiometers in an 'electronic' module there which tell the engine ECU what the pedal position is and one of them may be playing up, by the look of things.

 

Lastly, isn't your engine timing chain-driven rather than belt?

 

Edit: beaten to it...

[skylineskoda]

I think he said "sync(hronisation) chain" and when I googled it I found timing belt, my bad. The mechanic I went today without even looking at the car said what the problem is, because the engine is knocking (what he said) and it does indeed make a knocking sound. Few days ago another mechanic assumed that could be the problem after having a quick look. And the third mechanic gave me a different diagnosis based on the fault codes and pretty much told me to get rid of the car.

Engine is 8V, diagram and photo are helpful, do you think I could change camshaft position sensor on my own?

It may be an old pushrod engine but it still has a camshaft and because it doesn't have a distributor it uses a cam position sensor to trigger the dual wasted spark ignition system.

It's only a five minute job. Just the connector and one screw holding it.

hello... Just wondering, does anyone know if the problem was solved and how, cause i get exactly the same with my fabia and cant figure it out... thanks

[spiros90]

Any ideas out there guys... would appreciate any help or ideas... i get the same faults as shown on the pics above, have already changed the camshaft sensor and cleaned the throttle valve but still the faults are there...

Throttle pedal unit?

[spiros90]

Throttle pedal unit?

Haven't changed the throttle pedal unit yet, but do you think that could be it? And if so, why the rest of the faults, like camshaft and load check...?
