passager speed sensor rear
Why do you need a passenger speed sensor ? The passenger should be going the same speed as you and the vehicle are going.
Are you talking about a passenger sensor, which is in the seat and connected to the air bags, or a wheel speed sensor, which would affect the brakes? Either is a safety issue and needs to be corrected. Please tell us more and someone–not named Volvo–can help.
If you can not articulate a specific question or concern, I am surely not going to play 20 questions.
