P0725 Subaru Code - Engine Speed Input Circuit Malfunction
Quick Answer
The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM). Common causes include Faulty Crankshaft Position (CKP) Sensor, Crankshaft Position (CKP) Sensor harness is open or shorted, Crankshaft Position (CKP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

I believe I produced this error code by letting my 3.0r wit 5AT roll with engine off downhill in traffic jam.
Don't know anymore if the transmission was in N or D mode, i guess it was in D mode.
In my opinion this makes sense because the ecu/transmission wondered why the car is moving while the engine is not making any movement. Check Engine Lights and cruise control error lights were on, but turned off after about 15 Kilometres. The fault code was still readable with freessm.
Hope this helped you and maybe calmed you down a bit ;)German/Deutsch:
Ich vermute, dass ich diesen Fehler selbst verursacht habe indem ich in einem Stau bergab meinen legacy 3.0 mit 5-Gang Automatikgetriebe rollen ließ. Ich weiß nicht mehr genau, ob das Getriebe in N oder D stand, ich glaube aber es war D. Meiner Meinung nach macht der Fehler auch Sinn, weil das Motor/Getriebesteuergerät sich 'gewundert' hat, dass sich das Auto bewegt, obwohl sich der Motor nicht dreht. Motorkontrollleuchte und Tempomat Fehler Lampe brannten, gingen aber nach ca. 15 Km aus. Mit FreeSSM ließ sich der Fehler dennoch auslesen. Ich hoffe ich konnte helfen und beruhigen ;)
