Intermittent open or short to ground conditions can be detected by the IDM through IDM stuck high or low codes (1218 & 1219). POSSIBLE CAUSES OTHER DTC’S WASTEGATE STUCK DIAGNOSTIC PROCEDURE NOTE: Refer to VERIFICATION TESTS for appropriate verification test procedures.

It remained open the rest of the drive and and didn't magically close overnight. (On is *not* start!) The "check engine" light will flash. AOL`s stolen my picture!. If you are trying to get 7 PSI base boost, but in order to get that level of base boost the rod must be made too short (which will reduce the amount that the wastegate can open overall and cause run-away boost at high RPM's), you can set the base boost down around 6. 300sdl Turbo Removal- Wastegate stuck open So, my symptoms are that the wastegate is stuck open, ie.

If it is stuck open, some signal pressure still reaches the wastegate. • TC wastegate regulating solenoid valve stuck • Wastegate stuck open • Wastegate control hose open or plugged • Air leak between turbocharger and throttle Diagnostic Aids: Check tubing for restrictions, cracks and incorrect fitting connections. Start studying ASE A1 - Practice Test (Section E) Documen term 2 set 8. With the ability to vary the flow of exhaust gasses across the turbine wheel, variable geometry turbochargers (VGT's) get us as close as possible to having the best of both worlds.
