C0245: Wheel speed sensor frequency error
Drive carefully. Get it checked within a week or two.
Can I drive with C0245?
Yes, but drive carefully and get it checked soon. Wheel speed sensors are reporting drastically conflicting vehicle speeds.
What does C0245 mean?
C0245 stands for Wheel Speed Sensor Frequency Error.
Symptoms you may notice
- ABS, Traction Control, and StabiliTrak warning lights illuminated
- Anti-lock pulse disabled during wet or panic stops (normal brakes work)
- Cruise control disabled by brake safety interlock
How much does it cost to fix?
Repair costs for code C0245 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:
- Mismatched tire sizes or severely uneven tire pressure
- Cracked or missing teeth on an ABS tone ring
- Debris stuck on magnetic wheel sensor ring
- Worn wheel bearing allowing sensor gap fluctuation
What to do next
- Check tire pressure on all 4 tires with a gauge.
- Verify all four tires are identical in size and profile.
- Inspect ABS reluctor rings on drive axles for rust cracks.

About this code
Code C0245 means the brake computer detected conflicting speed frequencies between wheels. If you installed a compact spare donut tire or have one tire at 15 PSI while others are at 35 PSI, this code will trigger. Check tire pressures before replacing parts.
