Code C1161 Infiniti Description

The C1161 Infiniti code refers to an issue with the Side G Sensor Set in the vehicle. The Side G Sensor, also known as the lateral acceleration sensor, is a crucial component of the vehicle's safety system. This sensor is responsible for detecting the vehicle's lateral (side-to-side) movement and providing data to the vehicle's stability control system. When the sensor detects excessive lateral acceleration, it sends signals to the vehicle's electronic control unit (ECU) to help stabilize the vehicle by applying brakes to individual wheels.
