Useful checks before replacing parts
- Compare pressure sensor readings with pump command, pressure unit cycling, shift events, fluid temperature, and actual pressure if available.
- Inspect sensor reference and ground stability, connector condition, fluid condition, hydraulic restrictions, and pressure-control behavior.
- Check whether the fault appears during pressure build, engagement, hot operation, or rapid actuator movement.
