The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.

I just bought this car from a used dealer last month haven't driven 6 times yet and now this month it is stalling out we thought it was the fuel filter so we replaced that but now I tried driving it again and I got an error message saying "etc engine failure safe mode" the ca then began slowing down and I was unable to accelerate my speed. The car was also jerking as if it would cut off so. *tr
