Front wheel speed sensor fault?

Mid-life-crisis · Apr 28, 2024

I have an occasional fault on my 2002 3.0 Range Rover which feels like the front right brake is binding. To relieve it I can touch the brake pedal and the fault clears temporarily. Shortly after it happens, the dash lights up with the usual array of faults including inactive suspension and ABS

I've replaced the front pads (which should have been replaced a while ago)

Among the list of faults my IID tool lists "Front Left Wheel Speed Sensor Open Circuit".
The dash resets OK when I clear this.

Does it seem plausible that a fault in the front LH wheel speed sensor (I presume this is the ABS sensor) results in locking the brake on the opposite front wheel?

Thanks

If the ABS ECU sees a speed difference across the axle due to a faulty ABS sensor, it may well apply the brake on the opposite wheel because the ECU assumes the wheel has lost traction.

Thanks - that's fantastically logical.
I'll investigate and let you know what happens. I may even replace the track rod end too!
