Turbocharger/Supercharger Wastegate Solenoid "B" Low
▶ How to fix
Check the connectors and wiring to the wastegate actuator. Check the wastegate actuator Measure resistance of wastegate actuator, the resistance shall be around 30 Ohm at 20º C.
What you'll see
No driver-visible symptom recorded.
System reaction
The wastegate actuator will not work which might impact turbo performance and the wastegate over speed protection.
Diagnostic depth
Detection
Short circuit low to battery voltage (U30) or short circuit high to ground (U31)in the Wastegate actuator circuit.
Possible cause
Short circuit low to battery voltage or short circuit high to ground in the Wastegate actuator circuit.
