Title: ABS
Post by: Cable on 09 June 2009, 22:11

i have hooked up my voltmeter to the rear wheel sensors, one of them reads 3.0 volts at 30 mph, and the other one reads 4.5v so then i hooked up one of the front ones and it reads 2.5v at 30 mph, i take it this isnt normal?

You not supposed to measeure the volts.

You are supposed to measure the resistance.

Turn it Resistance at 20, not 200 or 2000.

nah resistance will only measure the resistance in the coil, i checked them and they were all fine, i wated to see what it would read when the car is moving, and the sensors produce an alternating current, but im guessing the air gap needs to be changed but how?
