New owner and error codes already....

A perfectly logical and well thought out answer young man .. i swear you are after my job here :D

joking aside it's a good point .. the reluctor rings do indeed corrode .. the car looks at these .. the normal fault with corrosion on them is an abs activation at low speed though but this is a point worth checking :thumb:

My trouble here is the fault code says it can't see or it gets an implausible signal from the steering angle sensor .. thats a sensor on the steering column that measures the angle of turn .. it's only accurate if its been calibrated though .. if not then it could well cause this issue .

let's just say if the car thought a left hand down was straight ahead ( calibration ) .. it then entered a corner on a right hand it would know the angle of the steering was more than the car could do based on the wheel speed sensors then it will throw a code .

Either way the car says at certain times it can't see this signal .. hence im leaning towards this being the issue ... car may well be confused though by the wheel speed sensors and the steering angle sensor and this is the best code it can throw up due to the circumstances .

Both need checking i feel and no offense but an excellent answer that i hadn't considered .

I do hate answering a comment other than the OP,s question .. i don't like to offend people :(
 
Thanks Grifter and deMort. Suggestions appreciated. These rings, if linked to the steering have to be on the front only?

I popped into an OPC and bought a switch today. When I asked for the part, the service person sat behind asked if I had ABS or PSM warning lights up and told me how often they needed changing back in the day!
 
The brake pedal switch has caused many PSM issues .. not seen a fault code for steering angle sensor because of it before but anything is possible .. always worth changing cheap items first and as something like this will fail sooner or later then its worth doing if only to eliminate it .

Reluctor rings are on All four driveshafts .
 
Excuse me, what is a reluctor ring? Something to do with the ABS is all I can gather. ... on each axle. Would it be the rotation transducer for the ABS so it can know what's going on?

Yes, the toothed ring which rotates with the driveshaft that the ABS sensor detects.
 
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 :x
 
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 :)

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...
