Change 1 2-1713 TM 9-2320-366-20-2 RESISTANCE TEST (1) Disconnect connector P72 from transmission engine speed sensor. (2) Set multimeter to ohms. (3) Connect positive (+) probe of multimeter to pin A of transmission engine speed sensor. NOTE A good transmission engine 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 0ohms at 230° F (110° C) (4) Connect negative (-) probe of multimeter to pin B of transmission engine speed sensor and note reading on multimeter. (5) If good resistance is not noted, replace transmission engine speed sensor (para 7-52). (6) Connect connector P72 to transmission engine speed sensor. NOTE Use care when testing electrical connectors. Do not damage connector pins or sockets with multimeter probes. Failure to comply may result in damage to equipment. Loose or dirty connectors may cause intermittent loss of power to transmission ECU and diagnostic codes to be logged. Ensure that all connectors are clean and tight before performing troubleshooting. Failure to comply may result in incorrect test results. CAUTION Wear appropriate eye protection when working under vehicle due to the possibility of falling debris. Failure to comply may result in injury to personel. WARNING Inspect connector pins/sockets for damage, corrosion, and serviceability. Check that connector pins are not pushed back and are capable of making good contact.
