Commodore, Caprice, Statesman (VF Eng)

Overview
These Vehicles were produced with the V8 Chevrolet Generation III 5.7L VF Engine.

It features Sequential Fuel Injection, Electronic Spark Control and Electronic Spark Timing.

They use a Powertrain Control Module (PCM) which controls Engine and transmission Operation.

The Transmission used is different to that used in the V6.

Close monitoring of Stoichiometric Air/Fuel Ratio is achieved by using Two Oxygen Sensors.

Diagnostic Connector
The 16 Pin Diagnostic Connector is located under the Right Hand Side of the Instrument Panel.

It is below the Steering Column.



Fault Code Extraction
Fault Code Extraction can be carried out Only with an OBDII Compatible Scan Tool:

Such as the OTC 4000 Enhanced.
Ps: These devices start from $4000

But if you have access to one of these!
