996 chime on acceleration?

[Porschedale]

On an '01 996 Carrera Cabriolet, at initial acceleration and about 5mph get a double chime tone. The fault code is #0055 and the description is "Steering Rotation Angle Sensor." What is and where is this sensor located in the car? What does it do and what kind of repair/replacement is needed?

New to posting. Thanks!

What did you use to get that fault code?

The Porsche code is:

Fault code 4440 Steering-angle sensor

Possible cause of fault:

- Short circuit to ground/B+ or open circuit

- Steering angle sensor calibration incorrect

- Wiring! plug connection faulty

- Steering angle sensor faulty

I would start by putting a PST2 or PIWIS tester on the car and calibrate the steering angle sensor. Then clear the code and see if it comes back.

Thanks for the quick response, and from "numero uno" himself! The code is #0055 and it is from the "Rotation Angle Sensor" not steering sensor - sorry, my error. And, obviously the code and chimes probably have nothing to do with each other. Hope that clarifies the question a little.

Thanks, Loren

Again - What did you use to get that fault code?

The chime is likely a set point on the OBC for speed control.

Dear Loren

I got this code 4440 1 week ago ( using Durametric ) when ABS & PSM Warning lights in the dash, I have a 2001 986 with Porsche approved waranty so I decided to vist my local dealer they said me that Steering Angle sensor was fault (Like durametric showed me).

Then they changed the sensor and recalibrated it ( They said ) after one day, I have the same warnings lights PSM +ABS so I connected again Durametric and I´t was the same fault code 4440.

Any idea? Could be also common brake swicht faillure or MAF ?

Thank you very much in advance

The brake switch is easy to test - do the brake lights come on?

Otherwise you may have a wiring problem per the possible fault causes above.

Thanks for your quick answer ;)

Yes, brake lights works ok but I suppose that it´s a double circuit switch, so maybe can fail PSM signal circuit, but I don´t know if this is correct

Do you think that could be a problem in wheel alignment?

Thank you very much :renntech:
