What P0E27 means
P0E27 marks short dropouts or jumps in the signal of inverter temperature sensor G. Between the events the reading is normal again, which is what separates it from the steady faults P0E25 and P0E26. No manufacturer documents P0E27 publicly; Mitsubishi, the one documented user of sensor G on the 2023 Outlander PHEV, checks that sensor for plausibility and for both voltage limits only. CARB expects hybrid sensor circuits to be monitored for circuit faults, which covers unstable signals as well. Likely sources are a connector with poor contact, a cracked solder joint on the sensing board or a thermistor with unstable resistance. The code can vanish before the workshop sees it, and the drive may be limited while it is active.
P0E27 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0E27
- Warning light that comes and goes
- Brief drops in electric drive power
Common causes of P0E27
- Most likelyIntermittent contact at an inverter connector
- PossibleCracked solder joint on the sensing board
- Less likelyThermistor with unstable resistance
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0E27 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 27 | The exact fault in that area. |
What to do next
- Note P0E27 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 P0E27
What does P0E27 mean?
P0E27 means "Drive Motor Inverter Temperature Sensor G Circuit Intermittent/Erratic". P0E27 marks short dropouts or jumps in the signal of inverter temperature sensor G. It is a generic code, so it means the same on every make.
Is it safe to drive with P0E27?
Drive gently and only to a workshop. With P0E27 the car can go into limp mode (reduced power) to protect itself.
Will P0E27 fail an emissions test?
Yes, it can. P0E27 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0E27 to fix?
Difficulty: workshop only. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P0E27 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
