Fault Family System: Powertrain (P-Codes) 3 SAE Codes

Crankshaft Position Signal Output

Diagnostic & Technical Explanation

Code P2617 (Crankshaft Position Signal Output Circuit/Open) covers the ECM's re-broadcast crankshaft position signal, a conditioned square-wave output that some platforms feed to a tachometer, ignition module, or auxiliary controller, and flags the line open, shorted low, or shorted high. Because the crank sensor's own input codes are separate, the suspects here are the output wiring between modules, the receiving device loading the line down, or the ECM's output driver stage.

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.
