C5 Gen 1 throttle body party number

[sifaan]

Hi

Can someone help me find the part number for 76343402 C5's motorised throttle body?
My service.citroen.com subscription doesn't work anymore (tried a new one but it asks for payment )

I need to get a replacement but want to be sure I get the right one

Thanks!

Hi Marc

That seems quite reasonable; just wanted to confirm that I could also look up other VIN's and not just my own (e.g. to make sure a car at the breaker's has the correct part; given that many parts for my car are no longer available new anyway)

Hi - Yes, I've responded to your Private Message.

[sifaan]

done; my VIN is 76343402.

Thanks!

Ok, so the part number for item (3) is 1920X1.
There's another part that it mentions: 1608878580 alongside the above. Anyway I've put pictures for both below.

I'm sure you'll know what you need.

Part 1920X1 £339.00	Part 1608878580 £90.90

Hi Marc

To my understanding, the motorised throttle body has the motor integrated;
this is what it looks like in my car (and I can't reconcile this with what's in the parts diagram / the pictures) - the block on the left is the motor, right?

Thanks

Ok, what you have in your pictures is the Air Intake Throttle Valve Housing, item (8).

Part 1635S7, currently priced at £344.93 inc. VAT from Citroen.

Thanks; even the aftermarket parts on ebay are 100 pounds plus and no one seems to be selling them used :/

The reason I wanted to change it (if I could get it cheap) was that there's a persistent MAP (Manifold Air Pressure) sensor error - even when cleared by Lexia it returns after restart; changing the sensor didn't help. So the mechanic was wondering if there was some problem with the throttle body that was causing the error.

This error has been present for years and I've just lived with it (although it perhaps contributed to reduced power / fuel economy) but more recently there's been instances (especially while the engine is still warming up to regular temperature) where the car doesn't respond to the accelerator (press it down but engine doesn't race) or has low power (need to switch off the A/C to go up an incline) and therefore I'm a bit more keen to fix it.

Could there be any other reason for this than the throttle body? The recent incidents were after an extended period of non-use during covid lockdown (needed some repairs but garages were not accessible), where the battery went flat and possibly the ECU "forgot" the driving pattern and had to relearn it? Because the problem is not as bad as it used to be immediately after the repair. Especially, in the first few immediately after the repair there was sometimes a problem where the engine RPM would fluctuate quite badly (surge slow surge slow etc) - stopping and restarting made it go away for the moment, and that hasn't appeared in a while now

Thanks

The only thing that comes immediately to mind is the MAP sensor - specifically, the quality. I don't know what brand you bought, but if you don't use a good quality brand then it is very possible it is either faulty or was dead on arrival. There have been multiple instances here where people have ordered these and other sensors from the likes of Eurocraparts and wonder why they still have problems. Turns out their quality is extremely questionable and parts are often faulty on arrival.

So I would double check the brand and would consider replacing that one more time with a decent brand.

Also, on this engine, there are separate sensors for the Air Intake Pressure and the Air Intake Temperature.

(10) is the Air Intake Temperature Probe (19204G) You can get a Magneti Marelli one of these for about £12
(7) is the Air Intake Pressure Sensor (457403). You can get a Magneti Marelli one of these MAP sensors for 18.59.

That's interesting; what I've replaced is 7; from a car being broken for parts, so hopefully was an original part (although maybe that owner had an aftermarket part to begin with). Many years ago when I got the car, the garage tried swapping the sensor with another car and the issue persisted, so they felt it wasn't actually a problem with the sensor at all - and indeed the change in 2017 didn't change it;

Should I try 10? Or 10 and 7?

Another complication is that I live in Sri Lanka, so would need to get these parts shipped to Sri Lanka - which adds quite a bit to costs and time, and therefore might be better to risk the 20 pounds to also get 7 than have to figure out how to get it from UK to Sri Lanka again.

Hopefully the last question on this topic - where do I find Magneti Marelli at those prices? ebay?

Thanks

I see (might be useful to update your profile with a general location).

Spareto ship to 50+ countries, so may be worth checking with them.

Hi again

(so unfortunately the previous post was not the last!)

The MAP sensor has been replaced not once (the incident I referred to in 2017) but twice - the last a few months ago
both were bought used, but the one I currently have is a Bosch and likely an original; while the other (from 2017) was likely an aftermarket one in the donor car

Considering the check with the swapped part (so altogether 4 sensors have been tried), I am guessing that the reason for the error (attached) is not the sensor itself - this car had had an electrical fire that required repair of the fusebox (which I subsequently replaced) and even replaced the engine harness (new part) so it's doubtful that the error is coming due to a wiring issue... the only other part I haven't replaced is the ECU (because it's really hard to find the matching ECU used)

If this error could arise from the Air Temperature sensor then I could try replacing that.

Thanks
