This is a brand new OEM replacement front left collision airbag impact sensor, designed as a direct fit for compatible Tesla vehicles. As a critical component of your vehicle's Supplemental Restraint System (SRS), this sensor detects front-end collision force and transmits real-time data to the SRS control module to ensure timely and accurate airbag deployment, protecting you and your passengers in the event of an accident.
Built to original equipment specifications, this sensitive replacement part delivers reliable performance and meets all factory safety standards for your vehicle's safety system.
✓ Direct OEM replacement matching original specifications for perfect fit and function
✓ Ultra-fast response time (under 5ms) to detect front-end collision force and intensity
✓ Built-in anti-error trigger design to prevent accidental airbag deployment
✓ Works with your vehicle's SRS control module to enable graded airbag deployment based on collision severity
✓ Reliable detection of impact force above 25km/h, triggering deployment within 10-30 milliseconds when threshold is met
As part of your vehicle's Supplemental Restraint System (SRS), this front left collision sensor works in sequence to protect occupants:
During a front-end collision, the sensor detects rapid deceleration and impact force through piezoelectric or inertial sensing technology
An electronic signal is immediately sent to the central SRS control module
The control module analyzes data from both front sensors to confirm collision severity
If the impact threshold is exceeded, the system triggers airbag deployment and seat belt pre-tensioning within 30 milliseconds
⚠️ Do not hit or impact the sensor or airbag installation locations. This can cause unexpected airbag deployment, resulting in serious injury or death.
⚠️ Never attempt to modify the sensor's installation location or angle. Incorrect installation can cause airbags to fail to deploy when needed or deploy unintentionally, leading to severe injury or death.
⚠️ Do not attempt to perform installation or maintenance on or around airbag sensors yourself. Always have this part installed by a certified professional technician at an authorized service center.
⚠️ If your vehicle's front bumper, frame, or body has been deformed after an accident, always replace all impact sensors and have the SRS system fully inspected to ensure proper function.
Replace your front impact sensor immediately if you experience any of these common issues:
Illuminated airbag warning light on your vehicle's instrument panel
Diagnostic trouble code (DTC) for front left airbag sensor circuit malfunction (such as B1149)
Previous collision damage to the front left bumper or frame
Corrosion or physical damage to the existing sensor housing
1 x Front Left (LH) Airbag Collision Impact Sensor (Part Number: 1473444-00-B)
