1. Visually inspect air injection hoses, fittings and components for damage and wear, and repair as needed.
2. Inspect wiring and electrical connectors to sensors control valve and computer, and repair as needed.
3. Ensure that engine is cold (coolant temperature below 43°F), then disconnect air bypass hose from air cleaner.
4. On models with High Altitude Compensation (HAC), disconnect lower hose from HAC valve and plug hose.
5. On all models, start engine and observe air flow from bypass hose. Air should be continuously discharged from hose.
6. Warm engine to 64---109°F while observing air flow from bypass hose. With coolant temperature in specified range, no air should be discharged from hose.
7. Warm engine to normal operating temperature and observe air flow from bypass hose. With engine at idle, no air should be discharged from hose.
8. Run engine at 2000 RPM while observing air flow from bypass hose. Air should be discharged from hose intermittently.
9. Momentarily race engine, then release throttle linkage. Air should be discharged from bypass hose for 1---3 seconds after throttle is released.
10. Locate system service connector under corner of left dash panel and remove cap from service connector.
11. Run engine at 2000 RPM, then connect a jumper wire between TWC terminal and terminal ``E'' in connector (parallel terminals).
12. Air flow from bypass hose should change from an intermittent discharge to a continuous discharge.
13. If system fails to perform as outlined, test components individually.
