Code P00C2 Cadillac Description

Each of the turbochargers is provided with a vacuum-operated bypass valve, which opens during abruptly closed throttle conditions, to prevent turbocharger surging and damage from vibrations. The bypass valve vacuum source is provided by a vacuum pump which is driven off the end of the right-hand exhaust camshaft. The valves are controlled by the Engine Control Module (ECM), by utilizing remotely mounted solenoid valves. When the valves open during closed throttle deceleration conditions, the air is allowed to recirculate in the turbochargers to maintain turbocharger speed. Within a calibrated range during a closed throttle event, or upon a wide-open throttle command the valves close to optimize turbo response.
As engine load and engine speed increase, the turbocharger bypass solenoid valves are commanded ON by the ECM. As soon as the throttle closes the turbocharger bypass solenoid valves are commanded OFF by the ECM to allow the bypass valves to open and allow the turbocharger air to recirculate to prevent surging.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects a short to voltage on the turbocharger bypass solenoid valve control circuit bank 2 for greater than 6 s.
