Senders sticking???

[snkbyt]

I have ShockWaves all four on my 36Ford 3 window with Ride Pro not auto level. I have it programmed to lift up when the key is turned on. I worked okay 1st year now the senders will stick. The LR will go to 170# then I tap on it and goes to 85#. I do a split second push to add or release air and goes to 170 again. 2 sensors stick. There is no water drains on system, is it possible the senders get water in them??? I checked the senders for a bad ground by doing a voltage drop to the battery and ony got a 1.3 MVolt drop from sender case to battery neg. When I hook up ohm meter to sender it shows the difference when it happens then tap on sender and ohms drop and pressure looks right. What kind or part # are the senders??? Any NAPA #s. I went to the senders from the gauges after tearing up a front fender on a turn from forgetting to air it up.:)

I am having the same problem with my s-10 right now, the bags fill up with all the pressure in the tank and i can let air out and they just fill up again. I have a 2003 s-10 with the road grater rear and coolride front kits and big red valves. Someone help me please...:(

BenS10, doesn' t sound like same thing. Mine will read false pressures so when you have it programmed to air up automatic when 1st start the control box sees wrong pressure and lets out or adds air the wrong way. One time it reads 170# on digital then tap on sender and reads 70#without changing air pressure.:) Yours sounds like something stuck in the switching valve. When I assembled mine I had your problem because I used thread sealer tape on some fittings. It went through the system and got stuck in the valve solenoid so it leaked. I took them all apart, AirRide Tech says don' t do it, and cleaned them out. That was 2 yrs ago and don' t have that problem anymore.

It' s a VDO sending unit. They are $25 a piece.
