What Does C1192 Mean?
The right front (RF) wheel speed sensor input circuit is shorted to battery voltage. The ABS module reads constant high voltage on the RF sensor signal line, preventing it from measuring the right front wheel speed. This disables ABS, traction control, and stability control. The corresponding warning lights will be on.
Safety Warning
ABS and traction control are disabled. No anti-lock braking protection on the right front wheel. This is especially dangerous in emergency stops and on slippery surfaces. Drive cautiously and have the repair performed promptly.
Common Causes
35%
Sensor signal wire shorted to a 12V power wire in the wheel well or engine bay harness
25%
RF wheel speed sensor with a failed internal output stage (Hall-effect type)
20%
Corroded or contaminated connector creating a conductive path to a power terminal
15%
Harness damage from road debris, underbody impact, or previous repair work
5%
ABS module input pin fault (internal short to supply)
Diagnostic Steps
1
Disconnect the RF wheel speed sensor connector at the knuckle. Clear codes. If the code changes character (e.g., to an open circuit code), the sensor is shorted internally — replace it.
2
With the sensor disconnected, measure voltage on each harness-side connector pin relative to chassis ground. Neither signal pin should have battery voltage (12V+). If battery voltage is present, trace the wire to find the short.
3
Inspect the wiring path from the RF sensor through the wheel well and along the frame to the ABS module. Focus on areas near power distribution (starter motor cables, alternator wiring, headlight harness).
4
Check the ABS module multi-pin connector. Look for bent pins, corrosion, or debris that might bridge the RF sensor pin to an adjacent power pin.
5
If all external wiring checks clean, use a breakout box or backprobe at the ABS module to check if the module itself is pulling the input high. Module replacement may be needed if it is internally failed.
