P0035 OBD2 Fault After Installing Turbosmart Blow Off Valve on 2018 Ford F150 EcoBoost
Hello, I recently installed a Turbosmart blow-off valve on my 2018 Ford F15-0 EcoBoost. The setup worked perfectly during the summer months. However, as winter approached, my engine light activated and the OBD2 diagnostic tool detected fault code P0035. I'm looking for advice on how to resolve this issue—could it be related to the blow-off valve installation or another modification? Any insights would be greatly appreciated. Thank you in advance.
Try removing the Turbosmart blow-off valve and reinstalling the original factory component. Clear the P0035 code using an OBD2 scanner, then drive under normal conditions to see if the error returns. Also, check whether you have any other modifications such as a performance tuner or ECU remapping, as these can interfere with sensor readings.
