MX-5 Miata L4-2.0L (2008)
Yaw Rate Sensor: Component Tests and General Diagnostics
COMBINED SENSOR INSPECTION
1. Turn the ignition switch off.
2. Connect the M-MDS to the DLC-2.
3. Select the following PIDs, then inspect the lateral. acceleration speed and the yaw rate.
-
LAT_ACCL: (lateral acceleration speed)
-
YAW - RATE: (yaw rate)
1) Lateral acceleration speed inspection
1) Verify the LAT_ACCL change when the combined sensor is tilted to the left and right.
^
If there is any malfunction, replace the combined sensor.
Standard
When the sensor is tilted to the right (A): LAT_ACCL changes negatively.
When the sensor is tilted to the left (B): LAT_ACCL changes positively.
2) Yaw rate inspection
1) Verify the YAW-RATE change when the combined sensor is rotated to the left and right.
^
If there is any malfunction, replace the combined sensor.
Standard
When the sensor is rotated to the right (A): YAW-RATE changes negatively.
When the sensor is rotated to the left (B): YAW-RATE changes positively.
