P0A5A Drive Motor A Stator Temperature Sensor Circuit Low

P0A5A indicates a low condition in the Drive Motor A stator temperature sensor circuit. The stator temperature signal is below the expected range.

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 assume Motor A stator temperature is actually low when the signal is electrically biased low.

Useful checks before replacing parts

Measure sensor signal voltage, reference supply, sensor ground, Motor A stator temperature data, freeze-frame conditions, and related low-input codes.
Inspect for short-to-ground faults, low reference voltage, connector corrosion, water intrusion, damaged wiring, and sensor resistance outside specification.
Compare signal voltage at the motor connector and module to determine whether the low reading is sensor, wiring, or controller input related.
