## Discrepancy

(CAN) ON TAKEOFF CREW GOT (WT ON WHEELS) CAUTION LIGHT MOMENTARILY.  LIGHT CAME ON AGAIN IN FLIGHT, QRH ACTIONED AND RETURN TO BASE.  PSEU SHOWED THAT RT MLG WOW 1 SENSOR PROXIMITY SHOWED  (UNREASONABLY NEAR). COULD ADJUST OUT SO THAT MILLIHENERYS WERE IN SPEC BUT THE GAP WAS OUT.  REPLACED SENSOR PROXIMITY. (TC NR 20070213006)
