Useful checks before replacing parts
- Measure sensor D signal, reference voltage, ground integrity, and circuit continuity while checking for short-to-ground faults.
- Compare live pressure D data with actual line pressure where available, commanded pressure, gear state, and fluid temperature.
- Inspect case connector terminals, internal harness damage, fluid intrusion, sensor connector fit, and related low-reference faults.
