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 replace hydraulic parts before testing the low control-circuit condition for pressure solenoid B.
Useful checks before replacing parts
- Check for short-to-ground, low resistance, damaged insulation, connector contamination, and driver-control behavior.
- Compare solenoid command with circuit voltage or current and transmission pressure response.
- Inspect shared power feeds and grounds if other solenoid control-circuit low codes are present.
