P0725 Hyundai Code - Failed Crankshaft Position Sensor Signal
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.

Discuss the causes and fixes for P0725 Hyundai OBDII Code

I previously have a error code advising crankshaft position sensor failure which was replaced approx 2 months ago. Car would stall at low speeds, would mis fire and was suffering with a loss of acceleration. when the car came back it was showing error code P0725 but I assumed this was just a left over code. After replaceing the sensor it worked fine for a couple of months but the issues have resurfaced. Mechanic who replaced it is now not responding to my attempts to contact him. I assume the part shouldn't have failed this quickly?
-
It's possible that the part failed, but some test that needs to be done to determine if there is something that is making the sensor failed or there is a poor connection or broken wire from the sensor to the Engine Control Module (ECM). I suggest having another mechanic inspect your vehicle.
