W163 ML320 2002 - Fault Codes P0720 and P0600: Diagnosis and Sensor Issues

Model: w163 ml320 Fault Code: P0600 Posted: 2016-02-13 20:03

I'm experiencing fault codes P0720 and P0600 on my 2002 W163 ML320. I've already checked and cleaned the sensors, and it appears one of them was replaced previously. Any insights or troubleshooting steps for these specific codes in this model? The P0720 indicates a malfunctioning output speed sensor, while P0600 points to a communication failure in the vehicle's control module. Could this be related to wiring, ECU connectivity, or a faulty sensor?
