• Q: How to replace the steering angle sensor on 2004 Toyota Prius?

  A: A proper start for steering angle sensor replacement requires disconnecting the battery negative terminal. The service technician must begin by unlocking steering wheel cover lower No.2 and lower No.3 before proceeding to extract the horn button assembly and steering wheel assembly using Special Service Tool: 09950-50013 (09951-05010, 09952-05010, 09953-05020, 09954-05021). First unclamp six claws which hold the steering sensor in place then take off the tilt lever bracket steering column cover with the spiral cable sub-assembly. Attach the new steering sensor to the spiral cable through the alignment of its two locating pins followed by disengaging the 6 claws. First inspect the spiral cable sub-assembly then align the front wheels straight ahead before reinstalling the spiral cable sub-assembly while centering it. After installing the steering column cover move onto the installation process of the tilt lever bracket and steering wheel assembly and horn button assembly. Finish by inspecting the horn button assembly before concluding the work. The last step involves reattaching the negative terminal of the battery followed by initialization testing and testing the SRS warning light operation.
