Emission Systems & Subsystems: Notes
CAUTION:
Do not insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal can cause a poor connection, which can result in system failures. Always use the Connector Test Adapter Kit (J 43907) to front probe terminals. Do not use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.
NOTE:
Manufacturer does not provide testing procedures for many individual systems and components. For emission systems & subsystems testing not listed, perform related DTC testing procedure. See SELF-DIAGNOSTICS - 2.2L SATURN "L" SERIES
