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 12, 14, 16 & 18: Wheel Sensor Intermittent Interruption
- Visually check appropriate wheel speed sensor and pulser installation as follows:
- DTC 12 - Right front wheel
- DTC 14 - Left front wheel
- DTC 16 - Right rear wheel
- DTC 18 - Left rear wheel
If a problem is found in wheel speed sensor or pulser, repair as necessary. If wheel speed sensor and pulser appear okay, go to next step.
- Disconnect 22-pin connector from ABS control unit. Measure resistance between appropriate terminals of affected circuit as follows:
- DTC 12 - Terminal No. 9 (Green/Black wire) and terminal No. 8 (Green wire) for right front wheel.
- DTC 14 - Terminal No. 7 (Green/Orange wire) and terminal No. 6 (Light Green/Black wire) for left front wheel.
- DTC 16 - Terminal No. 19 (Green/Yellow wire) and terminal No. 20 (Blue/Yellow wire) for right rear wheel.
- DTC 18 - Terminal No. 17 (Light Blue wire) and terminal No. 18 (Gray wire) for left rear wheel.
See Figure . If resistance is less than 450 ohms, check for short between 2 affected circuits. If resistance is 450 ohms or more, check for short to another wire in wheel sensor circuits. See appropriate WIRING DIAGRAMS. Repair short as necessary. If wiring is okay, clear code and test drive vehicle. If DTC resets, replace ABS control unit.
