C1145 - Right Front Wheel Speed Sensor Input Circuit Failure
Keeping this short and sweet
Currently tested
-ABS Sensor voltage unplugged: .3v to .7v when rotating wheel by hand
-ABS Sensor voltage at ABS terminal: .1v ~ .3v when rotating wheel by hand
-OHMs from ABS Terminal to Wheel Speed sensor: >.1ohms
-Voltage from ABS Terminal to Wheel Speed sensor: 2.3v~2.5v and 0 on other line.
-Fuses
Questions
What should I test next?
Why is there a voltage drop from terminal to sensor although the wiring shows no resistance?
Do you think replacing the sensor will fix the issue?
