瀚慖f less than the specified range, test the signal circuit terminal 4 for a short to ground. If the circuit tests normal, replace the K20 ECM.

6. Install a 3 A fused jumper wire between the signal circuit terminal 4 and the low reference circuit terminal 1. Verify the scan tool Boost

Pressure Sensor parameter is less than 1 kPa (0.15 psi).

瀚慖f greater than the specified range, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal,

replace the K20 ECM.

7. If the circuits test normal, test or replace the B65 intake air pressure and temperature sensor.

Diagnostic Fault Information

Circuit/System Description

The engine control module (ECM) controls boost using the turbocharger wastegate solenoid valve. The wastegate valve is actuated by a rod from

the diaphragm box located at the housing. A spiral spring in the diaphragm box works in the closing direction while the pressure in the diaphragm

works in the opening direction. The ECM supplies a pulse width modulation (PWM) signal to a solenoid valve, which then allows pressure from

the turbo to come through. When the pressure overcomes the spring force in the diaphragm box, the rod begins to move, opening the wastegate

valve to a corresponding degree. The ECM changes wastegate valve opening by varying the PWM signal, which regulates the turbine speed.

Ignition voltage is supplied directly to the wastegate solenoid valve. The ECM controls the solenoid valve by grounding the control circuit with a

solid state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can determine if the control

circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.
