P0ED5: Generator Phase X Current Low

P0ED5 means that phase X of the hybrid generator carries, or appears to carry, too little current while the generator is supposed to deliver torque. No manufacturer documents P0ED5 publicly. Mitsubishi publishes a comparable check for the U, V and W phases of the 2023 Outlander PHEV: with at least 50 A requested and the generator between 500 and 4,500 rpm, a phase current that stays within roughly 17 A of zero for 0.4 s sets P0E0C, as does a failed comparison with the target current. In phase X the same result comes from a broken phase cable, a burnt winding joint, an inverter switch that never conducts, or a current sensor stuck at its zero point. P0ED6 is the high case; the low codes of phases Y and Z are P0ED8 and P0EDB. Generator torque and charging suffer.

Symptoms

• Weak or no battery charging by the generator
• Rough engine start or vibration from the generator
• MIL and hybrid warning

Most likely causes

• Open or loose phase X cable or terminal
• Inverter power switch for phase X not conducting
• Burnt or broken winding connection in the generator
• Current sensor stuck near zero

What to check, in order

Start with the simplest. You can tick off each step.

1. Measure the voltage with the engine off and running
2. With the connector unplugged, check whether the signal wire is making contact with ground.
3. Clean and tighten the terminals
4. Check the accessory belt
5. Run a battery load test
6. Check the alternator wiring

Good to know

• It can trigger limp mode.
• It affects emissions.

What each character of P0ED5 means

• P: Powertrain: engine and transmission
• 0: Generic code: same on every make
• E: Subsystem depends on the code range
• D5: Specific fault in that system

Frequently asked questions

Can I keep driving with code P0ED5?

If the battery warning light comes on, you could get stranded. Turn off electrical accessories and go straight to a repair shop.

What causes code P0ED5?

The most common causes are: open or loose phase X cable or terminal; inverter power switch for phase X not conducting; burnt or broken winding connection in the generator.
