OBD-II Trouble Code Technical Description
Turbo Charger Bypass Valve Control Circuit Range Performance
What does that mean?
This diagnostic trouble code (DTC) is a generic OBD-II powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may vary depending on the make and model. Owners of these these brands may include but are not limited to VW, Dodge, Saab, Pontiac, Ford, GM, etc.
A code P0039 Turbo/Super Charger Bypass Valve Control Circuit Range/Performance is stored in turbocharged and supercharged vehicles when the powertrain control module (PCM) has detected a turbocharger or supercharger boost pressure bypass valve control circuit malfunction. A service engine soon lamp may also be illuminated. If this code is exhibited in a vehicle that is not turbocharged or supercharged, suspect a PCM programming error.
