Thanks to everyone for your replies...

Planohummer,

That's kinda what I thought it might be--a problem with the valve block/exhaust solenoid on the compressor assembly.

How long would it take to trigger an overtemp fault? The compressor stops in 20-30 seconds on it's own, but if I turn it on with the switch in the back of the truck (onboard air/hose) it stays on as long as I like. Wouldn't the compressor overheat and trigger the overtemp fault while using the switch/hose in the back?


Easy Ed,

I read your other post where you posted that photo of the filter and that was one of the first things I checked. My truck has a ceramic style filter and it looks OK.

How long did your compressor run before it shut down? Was your onboard air hose working and did the compressor stay on while you had the switch in the back turned on?


HUMTECH,

I had the driver side air line disconected from the air spring and the truck lowered all the way(to make the sensor think it needed to be raised)and no air was coming out of the air line(to air spring) while the compressor was running.

Is it possible that the new sensor is so far out of calibration, that it thinks the truck is too high(even when lowered all the way)?

Do you know the part# for the air lines if I convert from the old model to new model compressor?

By the way...Thanks for the tip you posted about rerouting the harness to the new version sensor. You saved me $150.


Thanks again,

John
