Hello,

The code P0103: Mass or Volume Air Flow Circuit High Input

One of the reasons for this code can be triggered is due to a leak in the air intake tubing.
Check for any loose connection or crack in the intake tubing.

Another possibility is a faulty wiring to the mass air flow sensor.

I have attached diagrams as well as the leak test procedure below.

Please let me know if you have any questions.
Thank you.
