Question
How to diagnose faulty turbocharger wastegate actuator in diesel trucks?
Answer
Monitor boost pressure and test actuator mechanical movement.
Explain
A stuck wastegate causes low boost. CHEPQ boost gauges measure pressure (<15psi indicates failure) and tools test actuator movement—adjusting or replacing the actuator restores proper boost and engine performance.
