RESISTANCE TEST Change 1 2-1721 TM 9-2320-366-20-2 (7) Connect negative (-) probe of multimeter to all pins in connector P119 (except P119p), one at a time, and note reading on multimeter. (8) Connect negative (-) probe of multimeter to ground and note reading on multimeter. (9) If good resistance is not noted in step 3, or continuity is present in step 4, 5, 7, or 8, notify DS Maintenance. (10) If good resistance is noted in step 3 and continuity is not present in step 4, 5, 7, or 8, replace WTEC III transmission ECU (para 8-7). (11) Connect connector P119 to connector J119. (12) Position front grille on cab with washer and screw. (13) Position two washers and screws in front grille. (14) Tighten screw to 48-60 lb-in. (5-7 N·m). (15) Tighten two screws to 24 lb-in. (3 N·m). (16) Clear diagnostic codes (para 8-5). (1) Set multimeter to ohms. (2) Connect positive (+) probe of multimeter to connector P119p. (3) Connect negative (-) probe of multimeter to connector P119r and note reading on multimeter. NOTE A good turbine speed sensor will return a reading of 200-400 ohms resistance as follows: a. 200 ohms at -40°F (-40°C). b. 300 ohms at 68°F (20°C). c. 400 ohms at 230°F (110°C). (4) Connect negative (-) probe of multimeter to all other pins in connector P119, one at a time, and note reading on multimeter. (5) Connect negative (-) probe of multimeter to ground and note reading on multimeter. (6) Connect positive (+) probe of multimeter to connector P119r.
