TM 10-3930-669-20 CONTINUITY TEST (1) Remove and ground sensor wire 19 (Para 7-41). (2) Set    multimeter    select    switch    to ohms. (3) Connect     positive     (+)     multimeter lead     to     engine     oil     temperature sensor. (4) Connect     negative     (-)     multimeter lead to a known good ground. (a) At room temperature, if resistance  is  other  than  400- 550  ohms,  replace  engine  oil temperature  sensor  (Para  7- 41).
