Thank you for taking the time to let us help you out with this problem and hopefully we can sort it out quickly. Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem. Sometimes it may take a moment for me to respond because I may have to look up information about your concern. I appreciate your patience and will provide responses as soon as possible. You'll have to get the seat sensor tested but yes there is a sensor in the passenger seat cushion that tells the srs module if there is weight in the seat. It's part of the passenger presence system. It's likely the seat sensor is bad. My goal is to give you the best service possible and to help you. If you have any questions or concerns, please don’t hesitate to let me know. If I’m not online at the time, I will respond ASAP when I get back.

Do you know about how much it is to replace the sensor?Do you know where it's located as maybe just something is unplugged?

It's plugged in under the seat cushion so you can check the connectors under the seat. It would cost around $900 to fix this sensor.
