I need to know what its supposed to be. I have an ABS light on right now and both front wheels are getting the same resistance as each other when spinning and sitting still. And my rear sensor has way more resistance than the front two and doesn't change with wheel speed.

I think it was 30-40k ohms.

Thanks for the help.

 

I remember testing my rear sensor and I beleive it had 1400 or 1500 ohms and did change slightly while spinning the wheels. The rear sensor is very cheap to purchase compared to the front.

 

Rear sensor should be around 1.5 k ohms

To dynamically test an ABS sensor, connect the meter leads to the sensor, set the meter to a low AC voltage scale, and spin the wheel. A good sensor will give several volts AC during this test.
