Code C0221 Chevrolet Description
The C0221 code for Chevrolet vehicles indicates that there is an issue with the right front speed sensor or its circuit being open. The speed sensor is a crucial component of the vehicle's anti-lock braking system (ABS) and traction control system. This sensor measures the speed of the right front wheel and sends this data to the vehicle's electronic control module (ECM) to help regulate the ABS and traction control systems. When the sensor or its circuit is open, it means that the ECM is not receiving the necessary data, which can lead to impaired ABS and traction control functionality.
Common Causes of C0221 Chevrolet
- Damaged or corroded speed sensor wiring
- Faulty right front speed sensor
- Loose or disconnected electrical connections related to the speed sensor
- Issues with the ECM receiving data from the speed sensor
- Physical damage to the right front wheel speed sensor
Symptoms of C0221 Chevrolet
- ABS warning light illuminated on the dashboard
- Traction control system malfunction light activated
- Erratic behavior of the ABS system during braking
- Loss of traction control on the right front wheel
- Increased stopping distance during braking
How to Fix C0221 Chevrolet
- Begin by diagnosing the specific cause of the issue using a diagnostic scanner to read the trouble codes.
- Inspect the wiring and connections related to the right front speed sensor for any damage, corrosion, or looseness.
- Test the right front speed sensor using a multimeter to determine if it is functioning properly.
- Replace the right front speed sensor if it is found to be faulty.
- Clear the trouble codes, reset the ABS and traction control systems, and perform a test drive to ensure the issue has been resolved.
Cost to Fix C0221 Chevrolet

Discuss the causes and fixes for C0221 Chevrolet OBDII Code
-
Yes it's possible, because the transmission uses the information from speed sensor to calculate shift timing and other functions.
-
Nice that a definition is given, but this info (like the Chilton) doesn't help me identify WHERE the sensor is, nor does it provide a diagram of the circuit. Collusion between the manufacturer and shop mechanics? Lol
Current issue is intermittent power when climbing hills.
