Make Use Of An Ohm Meter To Determine The Abs Sensor

It is clear to acquaint provided your ABS sensor is malicious.


When the brake light comes on, most individuals pep to the mechanic. Nobody wants the brakes to fail. Provided you obtain ABS, the mistake is oftentimes the ABS sensor. This sensor tells the braking system how lasting the wheels are spinning--and the braking action uses this dirt to come between you and the brakes when you are doing something that is going to lock them up. The sensor is manifest to jewel and facile to trial, and you can invest in one at the Car avail store for a sporadic bucks. With a petty attempt you might save hundreds of dollars.


Instructions


1. Attending in your van textbook to clock what the resistence is on tour Anti-locking Breaking Method (ABS) sensor. If you are using a multimeter, you should select the range that will put the needle (for the projected reading) in the middle of the scale. If the range setting is too low, the meter will peg for most readings, and if the range setting is too high the needle will barely move for a correct reading. Zero out the ohmmeter. The brake light does not indicate which sensor is causing the problem. Do not stop checking if you find a bad one--you might as well check them all.


2. Jack up the wheel you are checking and take off the wheel. The ABS sensor is a little canister with a wire coming out of it. Disconnect the wire and unscrew the canister. You can clean it off with a rag with a little brake cleaner fluid.


3. It is 50 ohms on most cars. Provided you obtain ABS on the front wheels only you Testament be checking the sensors for the front wheels matchless. Whether you enjoy ABS on all four wheels you Testament be doing this for all four wheels. Consulting the manual will tell you which arrangement you have. Unfortunately, you will have to replace the wheel and lower it each time. This means holding the meter leads firmly together with one hand and turning the zero adjust knob until the meter reads exactly zero. Now put the leads on the pins of the ABS sensor and read the resistance. It should be very close (within 10 percent) to the value given in the manual--if not, it is bad and should be replaced.
