P0107 code will not reset

Question

Mazda 6 diesel 2005 p0101 p0102 p0106 p0107, engine and traction lights on. Have replaced MAF sensor, no change. All codes will reset except the P0107 one which will not reset even with engine off. Does that point to an electrical wiring fault?

Answer 1

Hi there,

This is an electrical issue. Most likely the power feed to the maf sensor is bad, either a broken wire or a bad fuse. The code is setting as soon as you turn the key on which means the computer doesn't even see the sensor which means no power to it or the info line back to the computer is no good.
