Useful checks before replacing parts
- Compare hydraulic oil temperature rise with ambient, engine, transmission fluid, pump operation, and drive-cycle duration.
- Inspect sensor mounting, connector condition, reference and ground stability, harness routing, and fluid condition affecting heat transfer.
- Check whether the fault appears after cold soak, heat soak, long traffic operation, or rapid hydraulic pump cycling.
