Air Intake System: Notes
NOTE:
Many of the following tests can be performed only with PGM-FI Test Harness. Terminals on PGM-FI test harness connectors match terminals on ECU and ECU connectors. This allows the technician to test continuity of specified wires and resistance of devices when the ECU is disconnected. When ECU is connected to PGM-FI test harness, sensor input values can be monitored at the test connector terminals while engine is in operation. To identify ECU terminals, See Fig 1
