2015 Ford F150 4X4. 3.5 Ecoboost Twin Turbo
Replaced IAT Sensor, MAF Sensor, MAP Sensor. Cannot get the code to clear. Tried to reset ECM by disconnecting the battery. Code will not clear and performance still compromised. (Limited Power) Any ideas? Thanks

 

Have you ever thought of a bad wiring issue? Just remove the electrical connector, use electronic contact cleaner or 91% isopropyl alcohol to clean, also inspect the connector and its wiring make sure they look good visually.

 

Some newer vehicles require the repair be made and then the engine run .
If all is well , the code gets cleared by the PCM automatically.
