Air Intake System: Notes
NOTE:
Many tests can be performed only with Engine Control Module (ECM) Test Harness (O7LAJ-PT3010A). Terminals on ECM test harness connectors match terminals on ECM and wire harness connectors. This allows the technician to test continuity and resistance of vehicle wire harness and devices. Sensor input values can also be monitored while engine is in operation. To identify ECM terminals, see Fig 1
