Sensor output low during low-speed vehicle operation. Adjust speed sensor to contact
tone ring. Verify condition of tone ring mounting and teeth. Rotate wheel and verify mini-
mum 0.8 volts AC sensor output @ 1 RPS. Verify condition and retention force of sensor
clip. Verify proper sensor lead routing and clamping.

Intermittent sensor output. Adjust speed sensor to contact tone ring. Verify condition of
tone ring mounting and teeth. Rotate wheel and verify minimum 0.8 volts AC sensor out-
put @ 1 RPS. Verify condition and retention force of sensor clip. Verify proper sensor
lead routing and clamping.

Sensor output low or missing during vehicle operation above 10 MPH. Verify condition of
tone ring mounting. Adjust speed sensors to contact tone ring. Rotate wheel and verify
minimum 0.8 volts AC sensor output @ 1 RPS. Verify condition and retention force of
sensor clips. Verify proper sensor lead routing and clamping.

Verify condition and retention force of sensor clips. Check for corroded or damaged 
sensor and ECU wiring and connectors. Verify no continuity from sensor leads to
ground. Verify sensor leads are twisted pair.
