Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not condemn hydraulic parts before checking pressure sensor B wiring and whether pressure is actually high.
Useful checks before replacing parts
- Check for short-to-voltage, open ground, connector damage, internal harness faults, or pressure sensor B stuck high.
- Compare pressure data with commanded pressure, gear state, fluid temperature, and shift feel.
- Review pressure-control solenoid and line-pressure codes that may explain actual high pressure.
