Air suspension problem
I need help! I drive an 06 GX470, 185k miles. Recently the rear started to sag and the ride has become EXTREMELY bouncy. It seems like it’s just the passenger side so I assumed that it was the air bag that needed replacing. I searched the internet more and came across a YouTube video explaining how to fix this issue. A wire inserted into the 4th and 13th ports of the little connector under the steering wheel area and then repeatedly tapping the brake. Then restarting the car. It worked. The height adjustment was responding again, the ride was back to normal. However, it only lasted a couple days. And now it only last for 30min-an hour of drive time. My thought is the height control sensor but really I have no clue here. If it is the sensor, I understand there are more than one, how do I know which one needs to be replaced? Any help here would be GREATLY appreciated. Thanks in advance. I’ve searched a lot for this issue and haven’t been able to find much help.

Did the words “leak” in the air bag come up? Because there must be 2 million posts here about old, rotting, tired, achey, leaky air bags...12 Year’s old....those bags can only inflate and delfalte x amount of times before the rubber cracks. Height sensors can be, but are not the usual suspect. Compressor usually goes secondarily to the repeated inflation of the bags.
