Please help with throttle problem

Hello, even though I have an GTV I'm putting this tread here as my problem is related to the type of motor the throttle body is mounted on, I'll explain myself. The throttle body on my GTV is acting up and I've been told that I need to change it. I've been looking for a not so expensive replacement, the original part runs at over 1000 and I just cannot afford it. As for a used or commercial part there just seems there are no GTV throttle bodies to be found. My car has an 114kw, 2000cc Twin Spark 1998 motor with code ar32301. So I'm supposing that any Alfa model mounting that engine will have the same throttle body, can anybody confirm that?
I've run into various throttle body codes: Fiat, Alfa and Bosch and at the end and, believe me, a whole lot of research, I believe to have found what I retain is the right code: Alfa 60657874.
Can anybody confirm that a throttle with this code will fit in any Alfa model that carries the ar32301, 114kw engine version? Any additional information or clues would be very much appreciated. Thanks.

Kilowatts?


Assuming that's not some electric motor transplant and you have the 150bhp Twin Spark petrol engine, then yes the throttle body itself is part number 60657874.

However the throttle body is just a throttle body... usually alloy, maybe plastic... with an air regulator flap in it which opens when you prod the accelerator and closes on a spring... so not much on there that can go wrong.

It's more likely to be the BBoB on top... aka Injection Control Unit.. since that's got electronics in it. I dunno if you get one with a new throttle body assembly but you can also get the ICU separately - Art. 46768472.

The bad news is it's not much cheaper on its own than with the throttle body (assuming the assembly comes with a new ICU)... but you can get "reconditioned" ones for 1/2 - 2/3 the price of a new one - Art.71721936

The problem could also be the Throttle Position Sensor which again is "part of the Throttle body assembly" but is also available separately - - Art. 71713829


The beast sounds like a CF2 engine based on your TB part number.. and "any" TB off a CF2 engine will fit. The only odd-ness I see is that the ICU is different from a 145 or 156 CF2 engine, even though the TPS is the same.

If you can find a complete second hand throttle body with ICU and TPS from a GTV or Spider, then that will fit straight in. The 145/6 or '56's look like they can only provide the throttle body itself.. although your GTV ICU and TPS will fit on it.. (but see above re. TPS being the problem).

155 and 166 didn't have this motor... and the bits are tooo different.

Thank you for your answer. I've found a throttle body which I think will do for my car which is a phase 2 GTV with 155hp, year 1998.
I was wondering if you can help solve this ridle. I found a throttle body part number 0280750023. Will this fit my car?

Hi Ralf, I'm having a real hard time with the throttle problem and I just can't seem to
come up with a solution. My car is a phase 2 2000TS, year 1998 with 155 horse power
version.
I did not quite understand, if I get a throttle body for a cf2 engine the throttle itself will
fit but not the ICU or the TPS or both? It's now some months that I've been looking and
there just not any GTV throttle bodies to be found. The part numbers you gave for the
ICU and the TPS are good for the CF2 model with 155 horse power version? Also there
are usome things I just did not get like you talk about ICU Art. 4676847 and then add
that you can get reconditioned" ones for 1/2 - 2/3 the price of a new one -
Art.71721936. Are both of these ICU parts numbers? I seem to have understood that
Throttle body only is part 60657874. In EBay I've found this later part compatible with
0280750023 which comes complete of TOS and ICU. This later part always come from
Alfa 156 models. Is there any chance it could my car with the ICU and TPS?Only the
TPS 71713829 seems relatively easy to find at earthly prices.
I'm just going mad, please help. I don't want to ditch my beautiful car.
I suppose that all the art numbers are valid for my GTV version with 155hp?

That 0280750023 is a Bosch part number, not an Alfa one (Alfa has 8-digit part numbers).

It looks like it's a 145/156 part... so as above, the throttle body itself is the same as yours but the Injection Control Unit that these cars use is different to the GTV. If your ICU is faulty, this throttle body won't fix the problem (since you'd be fitting your ICU to the replacement throttle body).

You need a throttle body (with the ICU and Throttle Position sensor attached) from a GTV to be sure you're replacing all the parts that might be causing the problem.

Have a look for anyone breaking a GTV... such as these guys:

http://www.ebay.co.uk/itm/1994-2003-...EAAOSwt7ZXpm0r

I've never used them - just turned up on fleabay.. and they're specialist GTV breakers by the look of it, so they'll know how much a new one costs.. but they (or someone like them) will be able to tell you if they have a second-hand "CF2" Throttle body/ICU in stock. Some private sellers may be cheaper.. but unless they know what they're talking about, you won't be sure you're getting the correct part for your car.

Yes.. the Throttle Body for CF2 is the same on the GTV, 145 and 156...(60657874 is the Alfa number, 0280750023 is the Bosch number).. but the ICU for the GTV has a different part number than the ICU on a 145/156. I don't know what the difference is (could be internal programming and not very different.. or it could be completely different).

The part numbers I found are for a "CF2 GTV".. and these seem to be all the same... but if you have a chassis number I can check.

ICU #71721936 is a reconditioned version of new part #4676847. The moving pieces in #71721936 are new but the casing etc. is a cleaned up second hand one.. so its a bit cheaper. Only a dealer will be able to supply a reconditioned part.

Remember there is also a Spider with the same engine so you might find one of those when you're searching.

If you end up looking in Italy (as I have in the past) the throttle body is a "Corpo farfallato"... but again, check it has the ICU and TPS since the problem is likely to be those more than the throttle body itself.
