Topic: Has anyone actually solved for the common passenger air bag sensor failure?

[Rockchops]

As the title states...everything I read online is replace and calibrate. As parts become harder to find for this car, it's not really a scalable solution over time. Replacement is already about $400 and only comes as a built-in cushion sensor combo.

I have not read anywhere that someone has bothered to diagnose the root cause of the issue. To me it seems like a loose or broken connector throwing a bad signal to the CAN bus and tripping the default error code. Granted the wiring and signals are rather complex as they're going to a can bus but I doubt the actual weight sensor is anything more than a pressure sensor not unlike a truck scale...in which case it can likely be fixed easily (though perhaps not without tearing it apart).

Btw my light popped this weekend

The root cause has been found and discussed. The sensor array in the passenger seat cushion rips partially through a circuit pathway. There have been attempts by a few of us to repair the sensor array, but to no avail. I have also tried to make a sensor bypass module. That too, failed. Page 16 and on give the most detail to the problem.

Like Helios said.  Done and dusted: http://www.solsticeforum.com/forum/f12/panssenger-airbag-sensor-75353/index6.html#post1126380

Thanks guys, did not find either of those threads thanks to a couple hundred threads on "why do I have air bag error". Got some reading to do...will probably try and fix myself because there's no loss here.

Mine is lit also for a couple of weeks, I asked at the service (not dealership) an electrician to have a look at the sensor and let me know if it needs replacement, I'm waiting the answer.
