|P012D – Turbocharger/Supercharger Inlet Pressure Sensor Circuit High|
|Description: Manifold absolute pressure (MAP) sensor operating voltage is above the maximum calibrated parameter of 5 volts.
Possible Causes: • MAP signal short to voltage
• VREF circuit short to voltage
• Open circuit
Diagnostic Aids: The VREF voltage should be between 4.0 and 6.0 volts.
