What is this part and why does it matter?

The airbag impact sensor (crash sensor) detects sudden deceleration consistent with a collision, sending a signal to the airbag control module to trigger deployment.

Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Airbag warning light on the dashboard
  • Diagnostic fault code related to a specific impact sensor
  • Airbag failing to deploy in a collision (discovered after the fact)

Installation information

Bolts to the bumper, door, or chassis depending on location — always follow correct safety procedures when working near the airbag system.

Frequently asked questions

Different sensors detect different types of collisions (frontal, side) from different locations, allowing the system to deploy the appropriate airbags for the specific type of impact.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
