PTO Sense Circuit Range/Performance
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The PTO sense circuit is electrically intact, but the engagement feedback does not match the command. The ECM requests engage and sees no engaged feedback (or vice versa) within the expected time window — drive-line slip, sticky clutch, or a mis-adjusted limit switch.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
