Unfortunately I am unable to place a call on this here myself but others see you have requested a call and may still call on this here.I can however continue here.

If the sensor was replaced and the wiring was checked or replaced at the rear this indicates the fault is in the wiring leading from the wiring you installed to the air matic control unit or the fault is in the air matic control unit itself.

I would trace and inspect all wiring to see if any shorts, cuts or knicks are found needing repaired.If all wiring from this sensor is found to be o.k. then the air matic control unit needs replaced.
