'Transmission Range Multi-Function Select' is the multi-bit code of the shift-by-wire selector position: each position produces a fixed pattern of sensor states, and the module checks the pattern for logic errors. Mitsubishi's 2022 CVT with electric shift uses eight sensors (R: 1–2 on, N toward R: 1–5, home: all, N toward D: 4–8, D/M: 7–8). P07EC sets when a single bit does not change as the lever moves through its positions – it is stuck on or off. The other bits still identify the position, but the decision takes at least a second. Mitsubishi shows only the yellow electric-shift warning, without the MIL. Two or more stuck bits are P07ED.

Likely causes

One position sensor in the selector faulty
One sensor wire open or shorted
Dirt or sticking mechanism in the selector

Symptoms

  • Yellow shift warning or message
  • Selected range taken over with a delay of a second or more
  • No MIL (Mitsubishi)
