Before you buy anythingOn many vehicles the speed sensor is built into the hub assembly, so the fix is a hub rather than a standalone sensor. Check which yours uses before ordering, because the price difference is large.
What to do next
- Confirm the code with your own scan tool, or have it read free at a chain parts store.
- Decode your VIN so you know your exact engine and build date.
- Work down the causes above from cheapest to most expensive.
- Search NHTSA for a recall or service bulletin covering this symptom on your vehicle.
- Read the brakes buying guide before ordering.
C0035 is a generic OBD-II code, standardized across every make and model sold in the US from 1996 onward. The meaning is the same on any vehicle; the specific part and its location are not.
