2000 Chevrolet Venture V6-3.4L VIN EFACTORY OEM SERVICE PROCEDURE
General Description
The powertrain used in this vehicle consists of a 3.4L pushrod 60° V-6 engine mated to a 4T65-E electronically controlled transaxle. Refer to Engine Component Description in Engine for more information on the powertrain. The powertrain has electronic controls to reduce exhaust emissions while maintaining excellent driveability and fuel economy. The Powertrain Control Module (PCM) is the essence of this control system.
The PCM is designed to maintain exhaust emission levels to Federal/California/other standards while providing excellent driveability and fuel efficiency. Review the components and wiring diagrams in order to determine which systems are controlled by the PCM. The PCM monitors numerous engine and vehicle functions. The following are some of the functions that the PCM controls:
^ The engine fueling
^ The Ignition Control (IC)
^ The Knock Sensor (KS) system
^ The Evaporative Emissions ([1][2]EVAP) system
^ The secondary Air Injection (AIR) system (if equipped)
^ The Exhaust Gas Recirculation (EGR) system
^ The automatic transmission functions
^ The generator
^ The A/C clutch control
^ The cooling fan control
