Frequently Asked Questions: OE 12464820-00
How do I make sure this fits my Han EV?
The title names the Han EV, but this sensor fits several BYD models, so the title alone is not the check. Work from the fitment table on this page, find your model, then the build year, which you can read from your registration document, and confirm the OE number 12464820-00 or the alternative reference TA-3658400A-D1 against the sensor currently on the car. If your version is not in the table, use the quote route and send a photograph of the old part so we can confirm the match before anything is ordered.
My old sensor carries TA-3658400A-D1. Is that this part?
It is. TA-3658400A-D1 is an alternative reference for the same Front Impact Sensor II that carries OE number 12464820-00. Read the marking slowly and take every character, including the letters, because a reference of this length is easy to mistake. Once you are sure of it, match it against the two references shown on this page. If the marking is damaged or unreadable, use the quote route with your model and year rather than ordering on a best guess.
Is this a job for a garage?
It should be. This sensor is safety critical and belongs to the airbags and SRS group. Work on restraint systems belongs with a technician who has the manufacturer's procedure for the Han EV in front of them. You will find no fitting instructions from us on this page, because none exist for the part and we will not write them from assumption. Book the car in, hand the garage OE number 12464820-00, and let them verify the item before the old one is disturbed.
When will this arrive?
The delivery time is 8 to 25 days, from order to door. If timing is tight because the car is booked in, raise it through the quote route before you order so you know where you stand. The shipping cost for your country is shown on this page and confirmed at checkout before you pay. Before you order, check the number on your old part against OE 12464820-00.
What is the body of this sensor made of?
Plastic is the material for this sensor. Beyond the material name nothing further is specified, so we describe no grade and no coating for it. If you want to be certain it is the right shape, hold the images on this page against the sensor on the car and confirm the model in the fitment table before you order.
Where does this one sit on the car?
This sensor mounts in the engine bay, at the front. That is as precise as we can be on position, so we will not describe the bracket or the harness route. Your garage works from the manufacturer's layout for the Han EV, which carries that detail. Use the fitment table on this page to confirm the model and year first, then check the OE number 12464820-00 against the unit removed from the car before the new one goes anywhere near it.
Why is there only one version of this listed?
No aftermarket equivalent exists for OE number 12464820-00, so the Original/Genuine part built by BYD is the only version offered. Parts that do have a second tier show both on the same page, with each priced there, which means a single tier here reflects what we can source rather than a decision to hide anything. If you have been offered an alternative reference for the Han EV elsewhere, put it through the quote route with your year and we will say whether it matches.
