How to diagnose P0234, P0299

To see if this bulletin applies, first check the engine build date. If the vehicle was built on or before 2/28/2015, proceed with the following test. If it was built later, this bulletin does not apply.

Disconnect turbocharger wastegate actuator hose.

Connect a cooling system pressure tester with a pressure gauge to the turbocharger wastegate actuator.

Slowly increase pressure to the wastegate actuator and monitor the wastegate actuator rod. The rod should begin to extend at 3-9 psi and be fully extended at 12-19 psi.

Also, the wastegate shaft and arm should move smoothly from closed to fully open. If the wastegate actuator and arm operate smoothly and at the above pressures, this bulletin does not apply. If the wastgate actuator and rod don’t work smoothly or at the pressures listed, replace the turbocharger.
