P25B4 — Turbocharger/Supercharger Wastegate "A" Stuck Closed
Turbocharger/Supercharger Wastegate A Stuck Closed

Hello,

we have problem with Escape 2020 Turbocharger , 

We have replaced complete Turbocharger (old one had P2AB8 - Wastegate Position Sensor A Circuit Low ), we thought solenoid sensor is damaged

Unfortunately when we replaced turbocharger new DTCs appeared .

Attached txt file from Forscan log file which shows: -WGATE_A_OFFSET: Yes - Wastegate -A- Position Sensor Offset Is Invalid

My question is there is a way to calibrate , set offset ? It is around 1 mm of difference between real value and strategy.

Attached pids FDRS , Forscan log file and picture of waste gate solenoid (it is used in Edge … Escape … engines 2,0 EcoBoost)

If there is no mechanical adjustment that can be made, to change the relative position of the Wastegate, then the only thing possible, is to let it try and learn the new parameter.

Yes u are right , there is no mechanical adjustment (it is step motor) , unfortunately there is no service procedure for learn new parameter. Or there is a way but I don't see it ?, I am using FDRS (FJDS ,IDS ) and Forscan.

If there's no ‘reset’ in the IDS (I use one as well), then it may be just a case of a self-learn.
