C0080 code meaning
Wheel Speed Mismatch (Front Axle)
What C0080 means
Set when the two front wheel speed signals disagree by more than the allowed amount under conditions where they should match, pointing to a wheel-speed or tire problem rather than a single open circuit. The ABS/ESC module continuously compares left and right front speeds; a persistent mismatch on a straight road can mean a failing sensor, a damaged tone ring, a mismatched or badly worn tire or uneven inflation. Indirect-TPMS logic uses the same front-axle comparison to infer pressure loss, so this code and a low-pressure warning can share a root cause. ABS, traction and stability control may be limited and the ABS warning lamp is set while base braking remains. The entry follows the SAE J2012 generic definition and wheel-speed comparison diagnostics.

Symptoms of C0080
- ABS warning lamp on
- Traction or stability control limited
- Possible false low-pressure warning
Common causes of C0080
- Most likelyMismatched, worn or unevenly inflated tires
- PossibleFailing sensor or damaged tone ring
- Less likelyIntermittent sensor wiring
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of C0080 means
| C | Chassis system: brakes, ABS, steering and suspension. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 80 | The exact fault in that area. |
What to do next
- Note C0080 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0080
What does C0080 mean?
C0080 means "Wheel Speed Mismatch (Front Axle)". Set when the two front wheel speed signals disagree by more than the allowed amount under conditions where they should match, pointing to a wheel-speed or tire problem rather than a single open circuit. It is a generic code, so it means the same on every make.
Is it safe to drive with C0080?
Drive gently and only to a workshop. With C0080 the car can go into limp mode (reduced power) to protect itself.
Will C0080 fail an emissions test?
C0080 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0080 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will C0080 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
