C0080Wheel Speed Mismatch (Front Axle)
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- 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 tyre 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 tyre 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.
