ELECTRICAL SYSTEM TESTS, INSPECTIONS, AND ADJUSTMENTS - CONTINUED
THROTTLE POSITION SENSOR CIRCUIT TEST - CONTINUED
Inspect electrical connectors and wiring. Refer to Electrical Connector Inspection (WP 0022 00).
Place battery disconnect switch in OFF position (TM 5-3805-291-10).
Perform 10 lb (45 N) pull test on each wire in ECM connectors associated with ECM power supply.
Check J2/P2 ECM connector (socket-head screw) for proper torque of 60 lb-in. (7 Nm).
Check J1/P1 ECM connector (socket-head screw) for proper torque of 55 lb-in. (6 Nm).
Check harness and wiring for abrasion and pinch points from sensors back to ECM.
Expected Results. All connectors, pins, and sockets are completely coupled and/or inserted. Harness and wiring are
free of corrosion, abrasion, and pinch points.
If results are OK, harness and wiring are OK. Proceed to step 3.
If results are not OK, replace wiring harness in question (WP 0195 00 thru WP 0201 00). Ensure seals are
properly in place and connectors are securely connected. Verify repair eliminates problem.
