DTC P0052 Lexus

Description

Case 1 N-Signal Consistency N signal changing point must be specified position compared with last changing point. If the changing point differs more than 4degree, the failure is detected. - To avoid miss detection of failure, Changing point monitoring ignores the short term changing (less than 70ms). If N signal does not change more than 352 degree, failure is fixed. Case 2 Power-Supply-Short-Term-Defect Difference between measured steering-angle and expected-steering angle exceeds 6 degree. Too high velocity of steering-angle is measured. Expecting-steering-angle is made while power-supply state is out of range. Case 3 Signal Plausibility A failure is detected during steady-state straight ahead driving if one of the following conditions is true longer than 1.75s. 1. |longitudinal acceleration| gt;0.1g AND |difference| gt;3.0 2. -0.1g 6.0 3. -0.05g 9.0 - The difference : the difference between the reference signal and the steering angle sensor signal. - A steering angle reference signal is calculated from the wheel speeds, the lateral acceleration and the yaw rate to observe the steering wheel angle sensor. < longitudinal>< longitudinal>
