Any update on this op? What was the final diagnosis?
Cheers

Hi Rick, still work in progress. Car is in my garage until Saturday, when I will change the switch and hopefully, get a meter on the sensors nearby.

If that doesn't sort it, I am taking the car in for a look over to a local Indi in Horsham and they said they would advise/assist on any fault codes during that.

Next up-date from me Saturday PM!

Welcome to the 996 owners club...Sorry to hear you have problems.

If its any consolation, they are great cars and I'm sure once sorted you will get plenty of smiles per ££££.

Well, the brake light switch is changed and after driving around and stopping, clearing the old fault codes I have just driven for 5 miles with no warning lights.

Happy days if that is the solution. I am putting a few miles on the car tommorow so a proper report back on Saturday!

Well, that was short lived! The fault codes back and time for a trip to a specialist! Hopefully, it is just calibration, not a new sensor!

Still determined to try and fix this, yesterday I discovered that my fault code reader should be able to cope with Steering Angle Sensors (SAS!) but it appears that it can only calibrate from 997 onwards....

This thread had me itching to get under the car - http://www.911uk.com/viewtopic.php?p=1406016&sid=1f5d4393407f63ebe4f723f472d05eb1

Having removed and checked all 4 ABS sensors, they seem to be well sealed and have the resistance levels intended but I couldn't really see the reluctor rings suggested below?? I rotated the hubs and the resitance seemed to fluctuate consistently on all 4 corners, so unless all rings have gone wrong at the same time, I am expecting the resolution to be something else.

I did get excited (how sad is that!) when looking for the reluctor rings, to find a balance weight stuck in the area around the ABS Sensor on the front O/S hub but the warning lights live on Mad

I think we are moving a bit away from what the fault code says ..

At times the signal from the steering angle sensor is implausible .. the car doesn't understand it .. doesn't know the position of the steering wheel and so generates this code and a warning light .

Brake switch is a common fault but it doesn't normally generate this code .

reluctor rings if this system again can cause issues but not really generate a steering angle sensor code .

For me .. with a tester connected i can see the actual live values of the steering sensor .. hence i can see what the car sees ..

I can see if a calibration is required ..

In short then an Indy might identify the fault pretty quickly and whilst i realise the joy is in tracking down issues yourself ( i get the same feeling when finding a fault ) .. sometimes people like me might be cheaper Smile

Hi deMort, happy to pay you to have a look at it if that is available?

I have spoken with a couple of Indies and have decided to go with nienexcelelnce. When I can get there, they are going to go over the car with me (including fault codes!) However, they couldn't do a Saturday so its looking like w/c 25th.

The good thing about what I have been doing is, that I have now had a look over some of the car and whilst I don't know the subtleties of 911's, I have seen some things to put on the to do list. If this hadnt happened, I would have been wizzing around having fun and not found them!

9E is closer to you than me so that's fine .. i'm a good 20 miles further south and ken knows what he is doing .

It's probably not a saturday job to be fair .. all of us are short handed then and just doing pre set jobs and not really diag jobs .

Well, I was out to a meeting today and arranged for a new car/customer inspection with 9 Excellence. Thoroughly nice people and thankfully, my impuslive car swap has landed me with a 911 that is in fairly good shape. A reasonable to-do list and a couple of things for piece of mind.

To the matter at hand, they found a bunch of fault codes related to low volts and cleared all of those for me and no more 4440 or at least there wasn't until I was a few miles down the road!

After stopping somewhere else on the way home, I wondered what would happen if I switch off the PSM from the start-up and that seems to mean that the ABS warning light came on in about 2 miles instead of the normal 0.5-1 Mile..

Given this was all completed on the house, I didn't think it appropriate to go back for further investigation! When I get some of the work completed in the next couple of weeks, the steering angle sensor investigations will hopefully resume...

I have and have always had nothing but respect for 9E .. they concentrate on performance which is something i struggle on .. if it ain't Porsche then i struggle lol .. said that many times ...

Dam shame they are so far away from me .. sigh .

But i digress ..

Did you clear the low voltage fault codes before you visited them ?

if so they have come back so that's an area of investigation .

For me and what you have said then there is an issue with the steering angle sensor .. whether that's the sensor or wiring i can't say but i do think a garage needs to be looking at it and trying to find the fault as for now i think you might just be throwing parts at it trying to fix this fault .

My 2 pennys anyways .

Hi deMort, I spent a few minutes chatting with Ken today, the owner of said place and referenced your advice. He knows or knows of you!

My fault reader didn’t have any voltage related codes showing last week, but the car definitely had less volts then than now - low 13s on the individual sensors measured by the reader.

if that is significant or not, I am not sure but they only found wear and tear type things to factor into future maintenance on the car, which is probably a good thing!

I find it a little strange that you cleared the low voltage codes only for them to come back ..

low voltage will cause steering angle sensor faults .

It may be a red herring but it's something that needs investigating .

I've never actually met Ken but have spoken to him and of course chatted to him on this forum so we do know each other Smile

We are technically in competition with each other but as i don't represent my garage on here then i'm free to advise 9E for work to be done when i want to Very Happy

Hi deMort, I haven't seen any voltage codes on my fault code reader and looked for them today to see if that was linked to the code 4440 returning, but no low voltage codes visible, at least on my tester.

I did have a new code today - 4420 but no voltage ones!

When you 1st start up, you can see the sensor reading the turn of the wheel in degrees but when the fault comes along, you get no reading from the sensor which makes me think its something in the wiring or power to the sensor but what do I know!

I am enjoying learning the new car and how things work or not in my case Very Happy
