Quick answer

For a 2012–2013 Mitsubishi i‑MiEV (US), DTC P1D34 indicates an input-current sensor failure condition detected while the charging cable is connected. Verified TSB evidence states that charging is stopped as the fail-safe response and identifies the on-board charger as the probable cause.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does P1D34 mean?

For a 2012–2013 Mitsubishi i‑MiEV (US), DTC P1D34 indicates an input-current sensor failure condition detected while the charging cable is connected. Verified TSB evidence states that charging is stopped as the fail-safe response and identifies the on-board charger as the probable cause.

2. Technical explanation

The verified Mitsubishi service information describes P1D34 as “Input Current Sensor Fail.” It is evaluated when the charging cable is connected, and sets when the input current is an abnormal value. The same source separately describes P1D35 as an output-current sensor fault. The source instructs a technician to erase the DTC, perform regular charging, and check whether the DTC resets in the on-board charger.

3. What system is affected?

Charging system; specifically the on-board charger and its input-current sensing function.

4. How serious is this code?

The database does not assign a severity level. However, verified evidence states that charging is stopped when this DTC is present.

5. Symptoms you may notice

  • Charging stops or does not proceed when the charging cable is connected.
  • P1D34 may reset after the DTC is erased and regular charging is attempted.

6. Possible causes

  • Verified probable cause: failed on-board charger.
  • Not yet established by verified evidence: any additional causes.

7. Can I still drive the vehicle?

Not yet established by verified evidence.

8. Can I charge the vehicle?

No while the fault is active: verified evidence states that the charge is stopped as the fail-safe and backup function.

9. What you can safely do

  • Do not attempt high-voltage diagnosis or repair.
  • Have the vehicle evaluated by a qualified Mitsubishi EV service facility.
  • Record whether P1D34 returns after a normal charging attempt; this is consistent with the verified diagnostic procedure.

10. Step-by-step troubleshooting

  1. Qualified-service diagnostic procedure in the verified TSB: erase the DTC.
  2. Perform a regular charge.
  3. Check whether P1D34 is set again in the on-board charger.
  4. Further diagnostic steps are not established by the supplied verified evidence.

11. When to contact service

Contact a qualified Mitsubishi EV service facility, particularly if P1D34 returns after the code is cleared and regular charging is attempted.

12. What the service center may check

  • Confirm P1D34 in the on-board charger.
  • Clear the DTC.
  • Perform a regular charge.
  • Recheck whether the DTC resets.
  • Assess the on-board charger, identified by the TSB as the probable cause.

13. Possible repair or resolution

  • Verified evidence identifies the on-board charger as the probable cause. The specific repair or replacement procedure is not established by the supplied evidence.

19. Frequently asked questions

What does Mitsubishi i‑MiEV code P1D34 mean?

Verified service information identifies P1D34 as an input-current sensor failure condition. It is checked when the charging cable is connected and is judged when input current is abnormal.

What happens when P1D34 is active?

The verified fail-safe action is that charging is stopped.

What is the probable cause of P1D34?

The verified TSB identifies a failed on-board charger as the probable cause.

Does P1D34 apply to my i‑MiEV?

Verified applicability is limited to US-market 2012–2013 Mitsubishi i‑MiEV vehicles.

Can I drive with P1D34?

Not yet established by verified evidence.
