DTC 31, DTC 32, DTC 33, DTC 34
CODE DEFINITION - DTC 31, 32, 33, 34
| Code | Definition |
|---|---|
| DTC 31 | LF WHEEL SPEED SENSOR AIR GAP INCORRECT |
| DTC 32 | RF WHEEL SPEED SENSOR AIR GAP INCORRECT |
| DTC 33 | LR WHEEL SPEED SENSOR AIR GAP INCORRECT |
| DTC 34 | RR WHEEL SPEED SENSOR AIR GAP INCORRECT |
- Disconnect suspect wheel speed sensor connector. Using an ohmmeter, measure resistance between wheel speed sensor terminals. Resistance should be 1000-1200 ohms. If resistance is not as specified, replace sensor. If resistance is as specified, go to next step.
- Disconnect negative battery cable. Disconnect ABS ECM connector. ABS ECM is located on right side of trunk, behind trim panel. Measure resistance between ABS ECM connector terminals. See WHEEL SPEED SENSOR CIRCUIT RESISTANCE table. See Figure . If resistance is as specified, go to next step. If resistance is not as specified, repair wiring as necessary.
- Check continuity between ABS ECM connector terminals. See WHEEL SPEED SENSOR CIRCUIT CONTINUITY table. See Figure . If continuity is as specified, clear codes and retest. Problem may be intermittent. If continuity is not as specified, repair wiring as necessary.
