I have a diesel mazda 2 from 2004 in Europe.
I keep getting P0103 error code on OBD, even after cleaning the MAF. No check engine light.
The engine seems to run normal even with the error present.
I checked the MAF wiring and everything is ok, I think.
Wiring after testing with multimeter:
I don't know what can I do to fix it. Attached photos of error code and MAF+RPM graphs during a normal drive.

Wiring after testing with multimeter:
- 2 ground wires that have continuity with the battery
- 1 hot wire with 12V
- 1 hot wire with 5V
- 1 signal wire, 2.5V at idle (8 grams/second) and rises linearly with the RPM.
