Maybe your speed sensor is dead.. speed sensor is part of ABS system.. you can drive as usual except u have no ABS just regular brake.. and of cos u cannot read the speed.. drive to mechanic to properly identify the problem..

there are all 4 wheel speed sensors located one each at tires. the one that controls the speedometer is the rear left one. check that first and if not it is due to bad abs module. good luck.

Your odometer and trip meter will not work either if the speed sensors kaput. Mine had insulation worn out so wire was exposed. When it rained and the wire got wet, ABS light came on. Was coming back from outstation. Didn't know how fast I was going. In hindsight, should have turned on the phone GPS for speed guidance.

Hi, any contact/shop to buy the wheel sensor. I want to buy the rear left since my speedometer is intermittent with abs/asc lights are on. How about chop shop.. is it recommended?

Plug in diagnostic. It should tell you which side of wheel speed sensors causing the problem. It is located behind the brake disc. Once identified which one, remove it and and check contact and insulation issue first. As what ALIAS said it get easily worn out and expose. If the wire broken, just replace the wire. Mine just use tape insulator and it lasted for long time. Save money lorr.
