Signal.
Always
Pressure sensor or cable is bad on
the side indicated.
Replace sensor and cable
assembly. See XM PFP repair
manual.

controls. Allow ice to melt. Dry
compressed air. Heat compressed
air.
Use a smaller tip.
A pump is binding.
Repair lower. See XM PFP repair
manual.
A motor is binding.
Repair air motor. See XM PFP
repair manual.
