What P07EF means
'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). P07EF is the low state of the whole pattern: all eight bits report off, which is no valid code – typically a disconnected selector plug or a missing common supply or ground. Mitsubishi detects it already at standstill after about 10 s with the ignition on, puts the drive in neutral and lights the MIL.
P07EF at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P07EF
- Vehicle in neutral, no range selectable
- MIL and shift warning
- Fault appears right after switching the ignition on
Common causes of P07EF
- Most likelySelector plug disconnected or its supply or ground open
- PossibleSelector sensor board faulty
- PossibleElectric shift module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P07EF means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| EF | The exact fault in that area. |
What to do next
- Note P07EF and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P07EF
What does P07EF mean?
P07EF means "Transmission Range Multi-Function Select Circuit Low". '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. It is a generic code, so it means the same on every make.
Is it safe to drive with P07EF?
Drive gently and only to a workshop. With P07EF the car can go into limp mode (reduced power) to protect itself.
Will P07EF fail an emissions test?
P07EF is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P07EF to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P07EF clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
