Fault Family
System: Powertrain (P-Codes)
3 SAE Codes
PTO Output Control Circuit
Diagnostic & Technical Explanation
Code P260A (PTO Control Circuit/Open) sets when the ECM detects an open circuit, a short to ground, or a short to voltage on the output driver circuit it uses to command power take-off engagement hardware, distinct from the driver's enable switch input or the engagement-status sense circuit. Causes are a failed PTO engagement solenoid or relay coil, a corroded connector at the transmission-mounted PTO unit, or chafed output wiring in the chassis harness.
These 3 diagnostic trouble codes share one
detection mechanism and one repair path, which is why MechanicDB groups them into a single
authored fault family rather than repeating the same explanation 3 times.
