1982 Chevrolet Cavalier Base, 4D Sedan, Automatic TransSECTION System Performance Check
- This check verifies that CCC system is functioning correctly. This check should always be made after any repair on CCC system.
- When performing this check, always engage parking brake and block DRIVE wheels. Parking brake on front-wheel drive models does not hold drive wheels. On engines equipped with Varajet carburetors (E2SE Model), remove bowl vent line at carburetor and plug hose at carburetor during check and reconnect it after the check is complete.
- On some engines, the oxygen sensor will cool off after only a short period of time while engine is idling. This will cause engine to go into open loop. To restore closed loop mode, run engine at part throttle several minutes and accelerate from idle to part throttle several times.NOTE: Although there are many charts connected with CCC diagnosis, only 2 charts are needed to prove the system is operating properly. Normally* only 3 charts are necessary to find a problem, if one exists.
