Useful checks before replacing parts
- Graph pressure sensor data during pump operation, shift events, road vibration, hot operation, and harness movement.
- Inspect connector locking, terminal tension, internal harness movement, fluid intrusion, heat sensitivity, and shared reference stability.
- Compare intermittent signal loss with pressure-unit cycling, actuator commands, shift aborts, and freeze-frame voltage.
