Is it dangerous to drive with a faulty yaw sensor?

Yes, losing accurate stability control significantly reduces the vehicle’s ability to help you maintain control during a skid — this is a genuine safety concern, especially in poor weather.

Does this sensor need calibration after replacement?

Yes, typically it needs to be centred/calibrated with the vehicle on level ground for accurate readings.

What is the sensor made of?

A precision gyroscopic and accelerometer sensing element in a sealed housing.

Frequently asked questions

Yaw is rotation around the vertical axis — essentially how much the vehicle is spinning left or right relative to its direction of travel — comparing this to the steering input tells ESP whether the vehicle is going where the driver intends.

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.
