But there is a hint here of where to start. When you look up C1201 in a professional shop manual, the code is listed in the Vehicle Stability Control section of the manual. It has something to do with the stability control system. How Toyota vehicle stability control works The Toyota stability control system gets inputs from the yaw sensor, deceleration sensor and the ABS system. The ABS system gets its inputs from the wheel speed sensors. Wheel speed sensors have a pretty high failure rate, but when they fail, they usually set an ABS-related trouble code.

So don’t go chasing wheel speed sensor issues if all you get is a C1201 code. If the Toyota vehicle stability control system senses a wheel lock, a deceleration sensor or yaw sensor signal that indicates the vehicle is encountering a skid, swerve or is somehow going out of control, it operates the ABS brakes and reduces engine power to try and bring it back under control. Great, how does that relate to a C1271? Common cause of a C1201 Toyota trouble code If you perform any work on the steering, suspension or sensors, you can inadvertently set a C1201 Toyota trouble code. In order for the stability control system to work properly, it must know what the yaw and deceleration sensors report when the vehicle is stopped on a level surface. That’s referred to as a calibration procedure or zero point calibration. The calibration can be performed with or without a scan tool.

Perform a zero point calibration on Toyota to correct C1201 trouble code Park the vehicle on a level surface with no more than a 1° inclination. During the zero point procedure, do not vibrate the vehicle by tilting, moving or shaking it. Do not start the engine during the zero point calibration procedure. Clear the zero point calibration data 1.
