45-29Fault code 4440 · Steering angle sensor

911 Turbo (996) PSM 05 45 45-29Fault code 4440 Steering angle sensor Note! If the fault codes 4400 "Transverse acceleration sensor", 4420 "Rate-of-turn sensor" and 4440 "Steering-angle sensor" are dis- played together, there may be an open circuit in the circuit to con- trol module terminal 39. Diagnostic conditions • Steering angle sensor actual value is evaluated and displays an implausible value Possible cause of fault ♦Short circuit to ground/voltage or open circuit in circuit to con- trol module terminals 21, 39 ♦Steering angle sensor calibration incorrect ♦Wiring/ plug connection faulty ♦Steering angle sensor faulty Affected terminals Terminals 21, 39 Diagnosis/troubleshooting Note! Calibration of the steering angle sensor must be performed on a measuring platform. The steering angle sensor must be calibrated after work has been carried out on the running gear in the area of the front axle. The security code is required for calibration of the steering angle sensor. The security code is read with the PST2 under menu item "Actual values". Calibration is described in⇒Rep. Gr. 4560; Calibrating steering angle sensor. 4503 Fault code 4440 45-29 page 1 Printed in Germany – 4, 2001 4440ps05
