What does it mean to calibrate a steering angle sensor?
Calibrating the steering angle sensor is not just setting the angle to zero degrees, it is making sure the steering angle sensor is calibrated to the rest of the sensors that are part of the stability control system.
How does a zero point calibration work on a Toyota?
When power was restored to the vehicle. When the battery was reconnected, the wheels were still pointing left, and the steering angle sensor assumed this was close to zero. Toyotas use a reset procedure called a zero point calibration. The battery is disconnected at the start of the procedure.
What to do if zero point calibration is incomplete?
(1) Turn the ignition switch off. (2) Check that the steering wheel is centered. * If a DTC is output that indicates zero point calibration is incomplete, repeat the procedure starting at the step for clearing the zero point calibration data and system information.
How to calibrate torque sensor zero point in Toyota Prius?
(1) Stop the vehicle. (2) Hook up the TOYOTA hand-held tester to the DLC3. (3) Select the “TRQ SENS ADJUST” mode on the TOYOTA hand-held tester. (4) Select the “ZERO POINT INITIALIZE”. (5) Following the screen instructions, perform the torque sensor zero point initialization.

When to do yaw rate and acceleration sensor zero point calibration?
IF your 4Runner is equipped with either DAC or Crawl Control, you must complete steps 4 and/or 5 or you will get a DTC and the slip indicator will always be lit. I highly recommend this calibration if you think the VSC on your 4Runner kicks in too much, before or after lift.
