The lateral acceleration sensor, also known as the G200 sensor, plays a crucial role in your vehicle’s stability control system. A faulty sensor can trigger warning lights and error codes, impacting your car’s performance and safety. This guide will help you understand the Lateral Acceleration Sensor Location and the steps involved in replacing it.
Pinpointing the Lateral Acceleration Sensor
The lateral acceleration sensor is typically located within the vehicle’s interior, often near the steering column. More specifically, it’s usually positioned to the left of the steering column, beneath the lower dashboard panel. Accessing the sensor requires removing this panel.
Accessing the Sensor: A Step-by-Step Guide
-
Remove the Fuse Box Cover: Begin by removing the fuse box cover, usually located by the driver’s side door. You’ll likely need to remove several Torx screws to detach the cover and potentially a side panel for better access. While removing the panel attached to the fuse box itself may not be necessary, doing so can provide additional working space.
-
Detach the Lower Dash Panel: The lower dash panel is usually secured by several clips. Two are commonly found on the left side of the steering wheel, and one on the right. Gently pull the panel downwards and away from the dashboard. The left side might require slightly more force. Once loose, disconnect the connectors for the light controls and the OBD-II port. This will allow you to completely remove the lower dash panel.
-
Locate the Lateral Acceleration Sensor: With the lower dash removed, you should be able to see the lateral acceleration sensor. It’s often housed in a brass clip to the left of the steering column. The yaw sensor, a larger component, is usually located above it. Look for the brass clip; the lateral acceleration sensor will be positioned below it.
-
Identify the Sensor: The lateral acceleration sensor is relatively small. Here’s a close-up for better identification:
Replacing the Sensor
-
Disconnect the Sensor: The sensor connector usually has a clip on its side. Push the clip in and gently pull the connector to detach it. This step might require some maneuvering due to the confined space.
-
Release the Sensor Bracket: The sensor is held in place by a bracket that’s typically clipped at the back. Carefully lever the bracket downwards using a screwdriver to release the sensor.
-
Install the New Sensor: Position the new sensor in the bracket and push the clip back up until it snaps into place. Reconnect the electrical connector.
-
Reassemble the Dashboard: Reinstall the lower dash panel, reconnect the light controls and OBD-II port, and reattach the fuse box cover and side panel.
Confirmation and Troubleshooting
After replacing the sensor, clear any fault codes using a diagnostic tool. Check the sensor’s readings to ensure they are within the acceptable parameters. A test drive should confirm that the warning light no longer illuminates. If issues persist, consider using a diagnostic tool to reset the sensor values or consult a professional mechanic. You may also be able to repair the old sensor by carefully disassembling and cleaning the internal components.
