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 keep driving with suspected low transmission pressure; verify whether the low signal is electrical or hydraulic.
Useful checks before replacing parts
- Check pressure sensor E signal, reference voltage, ground, connector condition, and internal harness for short-to-ground faults.
- Compare pressure data with commanded gear, actual gear, shift timing, and fluid temperature.
- Inspect fluid level and condition where serviceable because low actual pressure and low signal faults need separation.
