Despite its name, 'Transmission Range Control A' is not the range actuator motor – that has its own codes, P272A and P272B – but the sensor circuits of an electric shift-by-wire selector. The only documented user is Mitsubishi's 2022 service manual for a CVT with electric shift (very likely the 2022–23 Outlander): the lever carries eight position sensors whose on/off pattern encodes R, N, home, D and M. P07E9 is the plausibility check of the sensor voltage: valid levels lie only in defined on and off windows, and a sensor sitting for 2.4 s in a forbidden band in between (0.6–1.07, 2.12–2.67 or 3.28–4.5 V) sets it – typically contact resistance, moisture or a sensor beginning to fail. Mitsubishi defines no fail-safe reaction. Note the title: 'Circuit Performance', not 'Range/Performance'.

Likely causes

Corroded or damp connector, contact resistance
Position sensor drifting
Shift module input

Symptoms

  • Electric shift or check engine warning
  • Usually no noticeable restriction
  • Further sensor faults lead to P07EC/P07ED
