Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC C1202, C1205, C1208 Or C1211: Condition
DTC sets when wheel speed sensor outputs no signal, such as when a large air gap exists between wheel speed sensor and tone wheel. This monitoring is performed for the period that the minimum velocity rises from 1.2 to 6.2 MPH. When minimum wheel velocity is 1.2 MPH and velocity of other wheels exceeds 6.2 MPH with an acceleration of more than 0.4g, HECU starts comparing velocity of the other wheels with each other. For DTC to set, wheel speed difference must be less than 2.5 MPH and continue for 140 msec. Exception is when the minimum wheel velocity is 1.2 MPH and maximum wheel velocity exceeds 6.2 MPH, and condition continues for 20 seconds or more. Possible causes are:
- Improper wheel speed sensor installation.
- Wheel speed sensor malfunction.
- Brake rotor malfunction.
- Wheel bearing malfunction.
- Wiring harness or harness connector malfunction.
- Hydraulic and Electronic Control Unit (HECU) malfunction.
