Diagnose Expedition P0234 or P0299, Navigator P0234 or P0299

Ford advises this diagnostic procedure:

1. Disconnect the hose at the turbocharger wastegate actuator.

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

3. Slowly apply increasing pressure while monitoring the wastegate actuator rod. The rod should begin to extend at 21-62 kPa (3-9 PSI) and be fully extended at 83-131 kPa (12-19 PSI). The turbocharger wastegate shaft and arm should move smoothly from closed to fully open. Does the turbocharger wastegate actuator and wastegate operate smoothly through the complete range?

Yes – this article does not apply. Refer to PC/ED manual for normal diagnostics.
No – replace the affected turbocharger.
