DTC C0222: Right Front Wheel Speed Sensor Signal Missing: Diagnosis
WARNING: This page does not describe the selected car, but rather 54 other vehicles, including the 1999 Oldsmobile Bravada, 1999 GMC Yukon, 1999 GMC Suburban, 1999 GMC Sonoma, and 1999 GMC Savana Special. However, it is still accessible from the selected car via links, so may be relevant.
- Perform diagnostic system check. See DIAGNOSTIC SYSTEM CHECK. After performing diagnostic system check, go to next step.
- Turn ignition off. Inspect right front wheel speed sensor, sensor cable and connectors for signs of damage or corrosion. Inspect wheel sensor toothed ring for looseness. Inspect 4-pin EBCM harness connector. If any damage is found, go to step 7) . If no damage is found, go to next step.
- Raise and support vehicle. Disconnect right front WSS harness connector. Using DVOM, check resistance between sensor terminals "A" and "B". See WSS TEMPERATURE-VS-SENSOR RESISTANCE table. If resistance is as specified, go to next step. If not, go to step 8) .
- Select AC scale on DVOM. Connect DVOM to sensor terminals "A" and "B". Spin wheel by hand while observing voltage reading on DVOM. If DVOM reads greater than 100 mV, go to next step. If not, go to step 8) .
- Disconnect 4-pin EBCM harness connector. Check resistance between harness connector terminals "C" and "E". If reading is infinite, go to next step. If reading is not infinite, go to step 10) .
- Reconnect all harness connectors. Test drive vehicle at speed greater than 15 MPH. If DTC C0222 sets, go to step 9) . If not, go to step 11) .
- Make necessary repairs.
- Replace right front wheel speed sensor.
- Replace EBCM.
- Repair short between wheel speed sensor circuits.
- Malfunction is intermittent. Inspect all connectors and harnesses for damage which may result in high resistance when all components are connected. See DIAGNOSTIC AIDS .
