Chart F4, RF Sensor Output
WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 1990 Pontiac Bonneville, 1990 Oldsmobile Ninety-Eight, 1990 Oldsmobile Eighty-Eight, 1990 Cadillac Fleetwood, and 1990 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
- Wheel Speed Sensors (WSS), that have an output of less than 50mV in Test F should be checked. Also any large differences in output between 2 sensors on the same axle (right/left front or right/left rear) should be checked.
- Signal strength of wheel sensor depends primarily on sensor gap. Low output is often caused by improper sensor mounting (including excessive gap), damaged sensor or wiring harness problems. It is important when replacing or servicing sensor to use anti-corrosive compound (P/N 1051344) between sensor and knuckle.
