Pasos de reparación

1. 1 Inspect the electrical connector at the turbocharger/supercharger bypass valve B for corrosion, damage, or loose pins, and clean or reseat as needed.
2. 2 Check the wiring harness from the ECM to the bypass valve B for chafing, bare wires, or short-to-ground conditions, and repair any damaged wiring.
3. 3 Measure the voltage at the bypass valve B connector with a multimeter to verify the control module is supplying proper voltage.
4. 4 Test the bypass valve B solenoid resistance with a multimeter and compare to manufacturer specifications to confirm it is within range.
5. 5 Replace the turbocharger/supercharger bypass valve B if testing confirms the solenoid is faulty or out of specification.
6. 6 Clear the diagnostic trouble code and test drive the vehicle to verify the repair and confirm the code does not return.
