Code result
P258E
PTO Enable Switch Performance
Moderate severity
What it means
The PTO enable switch is electrically intact but its state does not match operating conditions — for example asserted while the vehicle is rolling above the PTO speed limit, or asserted/de-asserted in fast succession. The ECM rejects the request to avoid unsafe PTO engagement.
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.
