Circuit Description
WARNING: This page is about a different variant/trim than selected.
Turbocharger wastegate is a vacuum actuated valve used to control exhaust gas heat sent to turbo. Wastegate pulse width modulated solenoid meters vacuum level at wastegate valve actuator as commanded by PCM. PCM controls wastegate solenoid by providing a ground path.
DTC will set when the following conditions are present:
- PCM requested wastegate solenoid on.
- Voltage on wastegate solenoid control circuit high (near battery voltage).
- Two consecutive faults detected.
- Conditions are met for 2 seconds.
Or
- PCM requested wastegate solenoid off.
- Voltage on wastegate solenoid control circuit low (near zero volts).
- Two consecutive faults detected.
- Conditions are met for 2 seconds.
