P07EC code meaning
Transmission Range Multi-Function Select Circuit
What P07EC 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). 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.
P07EC at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P07EC
- Yellow shift warning or message
- Selected range taken over with a delay of a second or more
- No MIL (Mitsubishi)
Common causes of P07EC
- Most likelyOne position sensor in the selector faulty
- PossibleOne sensor wire open or shorted
- Less likelyDirt or sticking mechanism in the selector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P07EC 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. |
| EC | The exact fault in that area. |
What to do next
- Note P07EC 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 P07EC
What does P07EC mean?
P07EC means "Transmission Range Multi-Function Select Circuit". '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 P07EC?
P07EC does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P07EC fail an emissions test?
P07EC 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 P07EC to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P07EC clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
