Useful checks before replacing parts
- Check pressure sensor signal voltage, reference, ground, open circuits, short-to-voltage faults, connector spread, and terminal corrosion.
- Compare pressure data with pump or pressure-unit command, shift feel, actual pressure if available, and related sensor codes.
- Inspect wiring disturbed during transmission service and verify the sensor circuit with the connector loaded.
