Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
A vacuum leak or pinched vacuum line could cause DTC P0236 to set. Check all vacuum lines and components connected to hoses for leaks or sharp bends. Check vacuum source. A possible EGR DTC will set if problem is present with vacuum source. Check for proper vacuum line routing.
The turbocharger wastegate actuator uses a pulse width modulated vacuum solenoid that causes vacuum to fluctuate under normal conditions. A steady vacuum reading indicates a restricted or plugged solenoid vent filter or solenoid vent orifice.
