P0941 Hydraulic Oil Temperature Sensor Circuit Intermittent

P0941 points to an intermittent hydraulic oil temperature sensor circuit fault. The temperature signal drops out or jumps only under certain conditions.

Code status

Needs verification

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

System: Transmission
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 clear intermittent temperature faults without stressing the circuit and reproducing the signal jump.

Useful checks before replacing parts

Graph hydraulic oil temperature during warm-up, road vibration, pump operation, heat soak, and harness movement.
Inspect terminal tension, connector locking, internal harness movement, shared reference stability, fluid intrusion, and heat-sensitive opens.
Compare the intermittent temperature signal with pressure unit cycling, shift behavior, and any related pump or actuator codes.
