P0A59 Drive Motor A Stator Temperature Sensor Circuit Range/Performance

P0A59 points to Drive Motor A stator temperature sensor range or performance. The value is present but does not match expected stator thermal behavior.

Code status

Needs verification

Not yet verified against SAE J2012_202509 / J2012DA. Treat unverified rows as a lookup aid, not repair authority.

System: Hybrid / EV
Scope: iso-sae-controlled-p0
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace Motor A hardware before checking stator sensor plausibility, cooling performance, and connector condition.

Useful checks before replacing parts

Compare Motor A stator temperature with motor load, inverter temperature, coolant flow, ambient temperature, freeze-frame data, and related cooling codes.
Inspect sensor mounting, connector fit, coolant level, trapped air, harness damage, ground quality, and motor or inverter connector sealing.
Monitor stator temperature during warm-up and loaded operation to identify slow response, sudden jumps, or implausible offsets.
