First time on the forum and im hoping someone can help me out.

I recently got the 15-3 opds sensor on my 04 rsx and im wondering if anyone can tell me if its possible to troubleshoot the sensor with a multimeter by using resistance setting? I know there are 3 sensor pads in the passenger cushion but how do I know which one is faulty? Also how do I test the opds module on the side of the passenger seat?

If anyone has ever done this please let me know. I could possibly buy a used passenger seat but I would like to know if its possible to test the sensors before I buy.

Thanks!
