Post Content

P00C2 – Turbocharger/Supercharger Bypass Valve B Control Circuit High
Description:                 The powertrain control module (PCM) continuously monitors the TCBY2 circuit for concerns.
This DTC sets when the PCM detects an open circuit or high voltage in the circuit.
Possible Causes:       
Damaged turbocharger bypass 2 (TCBY2) valve
TCBY2 circuit open or short to voltage
Diagnostic Aids:         
Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to contact with other components.
This DTC only sets when the valve is commanded open.
Description:                 The high pressure fuel system must reach a minimum pressure threshold before the engine can be started. If the high pressure fuel system cannot achieve this threshold within certain time and crankshaft rotation limits, the powertrain control module (PCM) attempts to start the engine at fuel pump module pressure and sets DTC P00C6.
Possible Causes:       
Fuel filter plugged or dirty
Fuel supply line restricted
Damaged fuel pump module
Damaged fuel injection pump
Diagnostic Aids:          Diagnose any FRP and FVR circuit DTCs first.
