Service Electric Throttle Control
P0299 - Turbocharger Underboost
P0401 - Egr Flow Insufficient Detected



While I was driving on the freeway yesterday I got a message on my dash telling me to service the electric throttle control. The check engine light also came on. I was able to continue the drive with no issues. When I was able to stop, I plugged in my engine scanner and I got the 2 codes. I was away from home and a few hours later I was able to drive it back home, no issues.

11 days prior I took my truck in to have two recalls serviced, 66A (Crankshaft Tone Wheel) and Z46 (High Pressure Fuel Pump). For 66A they had to flash the PCM.

Are my new issues possibly related to the repair for 66A?

Thanks.
