Details of the p0039 OBD Code
Fault code P0039 indicates a turbocharger or supercharger bypass valve control circuit range/performance issue.
OBD code P0039 means that there is a fault with the Turbo/Super Charger Bypass Valve Control Circuit Range/Performance.
This code is triggered by the Engine Control Module (ECM) when it detects that the voltage signal from the Turbo/Super Charger Bypass Valve Control Circuit is outside the expected range.
This code is related to the turbocharger or supercharger system in the vehicle.
Mechanic’s Tech Notes
Code P0039 indicates a turbocharger or supercharger bypass valve control circuit range/performance issue.
To diagnose and fix OBDII code P0039, which indicates an issue with the Turbo/Super Charger Bypass Valve Control Circuit Range/Performance, start by visually inspecting the wiring harness and connectors related to the bypass valve.
Look for any damage or corrosion on the connector pins.
Use a voltmeter to test the voltage at the bypass valve control solenoid.
Ensure the solenoid is receiving the correct voltage signal.
If the wiring and connections look good, the issue may lie with the bypass valve control solenoid itself, requiring replacement.
A scan tool can help monitor the bypass valve control solenoid’s operation and confirm if it is functioning within the expected range.
