Code result
P258F
Torque Management Request Output Signal
Moderate severity
What it means
The ECM/PCM produces a torque-management output signal for downstream consumers (TCM during shifts, hybrid module, transfer case) and detects a fault on this output — open, short, or feedback voltage outside expected range. Without it, downstream modules cannot synchronise their behaviour with the engine.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
