Abs problem 😢

[Steve7311]

can anyone help? I had my abs light come so I plugged my reader in and the rear left abs sensor is fluctuating ie, 2,4,1,5,18,1,3. This is happening with the van parked. I replaced the sensor and the rear hub. (The sensor isn’t original) if I unplug the sensor underneath it stays on 0 like the rest. I hope someone can help.
Thanks
Steve.

Bad contact either from the sensor to the chassis connector (which is at the end of the sensor wire) or the ESP connection - clean it with fluid
