seeing if anyone has any info on a F48a code showing up on a Deere 650j Seems to be fuel related it runs rough when giving it throttle
The code regards an issue with the crank position input signal..I assume yours is a tier 3 with a common rail fuel system? If so the sensor is located under the fuel pump on the left side of engine and should have 2500-3500 ohms of resistance between the terminals.
