P2617 is a diagnostic trouble code (DTC) for "Crank Position Signal Output Circuit Open". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
Crank Position Signal Output Circuit Open
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.
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.
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.
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
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
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.
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.
