P2617 code definition

Crank Position Signal Output Circuit Open

What the P2617 code means

P2617 is an OBD-II generic code for the engine control module (ECM) detecting an open or short circuit in the crank position sensor signal wire or sensor to the ECM.

What causes the P2617 code?

  • The engine control module (ECM) monitors the crank sensor during crank mode and will set the code if 5 crank signal returns are missed or if 10 signals are missed in the run mode.

  • The wiring to the crank signal return wire to the ECM is shorted or losing connection from corrosion in the connector.

  • The crankshaft sensor or connector is open or shorted.

What are the symptoms of the P2617 code?

  • The Check Engine Light will be illuminated and the code is set in the ECM memory as a fault.

  • The engine may not start or may stall if the problem is intermittent.

  • The engine may run good and then all of a sudden stall or run very rough when short occurs.

How does a mechanic diagnose the P2617 code?

  • Scans for codes and document any codes in the ECM, then looks at the freeze frame data for failure

  • Checks the crank sensor and wiring harness for cuts into the harness causing the short

  • Tests the wiring and sensor for shorted or corroded connectors and wiring

  • Checks the crank sensor resistance with the engine off, then checks for proper voltage signal generated during cranking

Common mistakes when diagnosing the P2617 code

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

  • Replacing the crank sensor without checking the wiring connector for corrosion or loose pins

How serious is the P2617 code?

Code P2617 is a code indicating the crank sensor return signal is open and cannot generate a signal to run the engine. The engine will not run as long as the problem is happening.

What repairs can fix the P2617 code?

Additional comments for consideration regarding the P2617 code

Code P2617 is most commonly caused from an internal crank signal failure. Some sensors will only fail when they get hot or after they cool down. Some sensors will only fail intermittently and may be difficult to duplicate and diagnose. Sometimes a replacement sensor has to be installed to test and see if it is the problem, if duplicating the failure cannot be done in a timely manner.
