Code 26 - Left Front Toothed Wheel Frequency Error: Notes

Toothed wheel generates a voltage pulse as it moves past sensor. EBCM uses these pulses to determine wheel speed. EBCM uses wheel speed sensor signal to calculate vehicle reference speeds and speed, acceleration and slip values for each wheel. These values are used to determine when anti-lock control is needed.

Code 26 will be set if improper speed signals are generated by toothed ring sensor. Some causes are incorrect number of teeth on sensor ring, sensor rings covered with dirt, grease or metallic particles, and damaged toothed sensor ring.

Code 26 may be set if mini-spare tire has been used or tire sizes on vehicle differ from each other.
