Code P258E 2016 GMC Sierra Description

The Power Take-Off (PTO) is an upfitter integrated system that allows the user to create an auxiliary power source. The PTO system specifically controls engine speed to values higher than normal base idle, PTO load relay engagement, and remote starting and shutdown of the engine. When the operator requests PTO using either the PTO switch or PTO remote, the engine RPM will increase to a default standby speed. The Engine Control Module (ECM) converts the data from the engine speed sensor to a 2 pulses/engine revolution signal. When PTO is engaged, the power take-off control module sends a serial data message to the ECM requesting engine speeds, in response to signals from the PTO switch or remote.
The Diagnostic Trouble Code (DTC) will be set when the Power Take-Off Control Module detects a fault on the PTO enable switch circuit that is above or below a predetermined voltage threshold.
