P0BE6: Drive Motor A Phase U Current Sensor Circuit Range/Performance
What to do
As P0BE5 — the sensor circuit, not the motor. Ask what is actually being quoted.
What this code means
The phase U current sensor circuit on drive motor A is returning a plausible value that does not match the other phases or the torque being commanded. The family's argument — and the four similarly-named codes it must not be confused with — is at P0BE5.
Likely causes
Start here
- Faulty motor current sensor · specialist
- Corroded or loose connector · easy
Less common
- Failed sensor reference voltage supply · moderate
- Faulty power inverter · specialist
- Chafed harness between transaxle and inverter · specialist

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
