Steering Angle Sensor 2007 Vantage

[Philipcollins340]

Hi All,

My Foxwell has identified a faulty SAS.
I see that AM want a silly price for this sensor on the steering column.
Does anyone have any input on an alternative supply . I cant see anything in a search for Volvo or Ford equivalent.

Any Help Appreciated.

I guess it is unlikely to be a one-off AM part.
Maybe try Jaguar - I recently replaced wiper&indicator stalks and they were Jaguar parts.

Sorry to hijack, but just out of interest: The steering column stalks are Jaguar? I thought Ford (Fiesta?), but maybe that means no contradiction at all?

definitely Jaguar X-Type - put it in the alternative parts - sticky page 5...and no contradiction, they were all under the Ford umbrella at some time.

As a matter of interest, do you actually have any warning lights on the dash?

Looks like a Panasonic part from this example on Ebay which is advertised as new;

Part No. 4G43 3F818 AA

https://www.ebay.co.uk/p/590621547




Edit: It looks like some Land Rover vehicles do have the same unit fitted, but with different Hardware and Software versions so probably not a good idea to mix?

Part numbers are similar, with only the first four characters changing.

Yeah, be interested to know?

too many sensors on cars nowadays ...

What does it do?

Reports steering angle position. In conjunction with other sensors (like ABS, yaw and linear acceleration) it allows the Stability Control System to work out what the car (and its driver) is doing or trying to do. And if it's going to let them do it.

Hi All,

Yes, I certainly do have the dreaded "DSC disabled/ Traction control temporary off" message and it was this that has prompted me to buy a Foxwell OBD sniffer. The SAS is faulty according to the Foxwell and is one of the several sensors that can cause this message to appear. I know there are others and they can be related so I am gathering enough data to justify buying a new SAS.

I am still in the process of getting this fixed and will report my findings when completed

Best regards

Looks like a very mechanical part to me. I'd be tempted to take it apart and see if there's any fluff in the system or broken bits.

Can't imagine the electrics will be that complicated either ?

From the article I referenced

Analog sensors use voltage differences to determine information about the angle and turn direction, while digital sensors use an LED light that measures the angle of the steering input. The sensor then reads and sends a minimum of two signals, often out of phase, to the ESC module, which then uses an algorithm to make sure the steering is accurate from the steering wheel to the wheels.

Not something I'd want to mess with, considering what it does.

if the OP wants to post it to me at my cost once replaced, I’m happy to have a look and post the results.

[Philipcollins340]

I saw a photo of the innards of a similar (but not identcal) part and it's complex.

Electronic parts included a processor and memory with application specific software. Software revisioon on the outside label.
Input angle was provided from a rotary potentiometer. These transducers are notoriously unreliable(same technology in your old
Hi-Fi volume control) so I may strip it and clean before parting with my money,
Another common cause of failure is corrosion on the PCB with some manufacturers not protecting the PCB.

First part of the investigation will be to check all fuses and reset all OBD errors where possible and charge the battery fully.
Waiting for the weather to warm up a bit!

It’s the potentiometer which would be my first port of call. Switch cleaner works wonders. I can see that area as an ideal trap for all sorts of fluff and dirt.

Not sure if this of any help but Volvo v70 (Volvo was also part of PAG) also are renown for these sensors playing up - just in case they are the same - unfortunately I don't have a spare item anymore to check it for you.

[Philipcollins340]

Thanks for your comments guys.

I have tried to find an alternative OEM that uses the same part but extensive web searches for Jaguar or Ford SAS have revealed nothing.
Further to that , I am thinking that the Panasonic sensor has bespoke software for the AM variant.

If you do end up buying a new one my offer still stands to have a look at the old one and I’ll pay the postage.

Could be a useful resource if we can work out how to fix them.

Hi Phil. I believe a lot of the Aston electronics are common with JLR and Volvo (from when they were also part of Ford's Premier Automotive Group, along with Jaguar and Land Rover (Aston could dip into the corporate parts bin as required).

If you are confident that the part number of your sensor is 4G43 3F818 AA, as stated above in this thread (I'm sure the parts department of your local dealer would confirm) then I tend to agree that it seems to be a unique AML part, as a Google search for the part number throws up only Aston links; if it were a shared part I'd expect to see links for Volvo as well, or JLR, or even Ford.
