What P2617 means
When an engine module relays the crankshaft position signal to another controller, P2617 says that this forwarded line is open or the pulses go missing at the receiver. Ford's 2003 6.0 L diesel summary describes the clearest case: the fuel injector control module counts a fault whenever the crank pulse it gets from the PCM is absent or does not line up with the camshaft signal, monitored continuously above 90 rpm, and the code carries a MIL in Ford's lists. GM notes that some of its controllers may store P2617 alongside P2618 when the output is open, and Mitsubishi lists P2617 for the 2022 Outlander. Low and high shorts are P2618 and P2619; a fault in the crank sensor itself is P0335/P0336. Without the copied signal the injectors may not fire, so stalling or a no-start is typical.
P2617 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2617
- Malfunction indicator lamp on
- Engine cranks but does not start
- Sudden stalling while driving
Common causes of P2617
- Most likelyOpen wire or pushed-out pin on the crank output line
- PossibleCrank sensor signal itself missing or out of sync with the cam signal
- Less likelyReceiving module (e.g. injector control module) faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2617 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| 17 | The exact fault in that area. |
What to do next
- Note P2617 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2617
What does P2617 mean?
P2617 means "Crankshaft Position Signal Output Circuit/Open". When an engine module relays the crankshaft position signal to another controller, P2617 says that this forwarded line is open or the pulses go missing at the receiver. It is a generic code, so it means the same on every make.
Is it safe to drive with P2617?
Drive gently and only to a workshop. With P2617 the car can go into limp mode (reduced power) to protect itself.
Will P2617 fail an emissions test?
Yes, it can. P2617 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2617 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2617 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
