after doing a front rotor /pad change on a 03 silv, i was told the abs coming on at low speeds could be fixed by pulling the abs sensor and cleaning the rust under it....well i pulled both sensors on the 2nd one i noticed some of the wire fillaments were coming off....so i did some research on this site and apparently the sensor have a sleeve over them that didnt come out when i pulled them out? anyhow when i was all done and back together i now have a abs light on in the truck...so can someone tell me are both these sensors junk now? is there a way i can test them?

Your sensor actually pulled apart while you were trying to remove it from the hub, causing the ABS light.

 

Anytime you remove the sensor, and the plastic collar stays lodged in the hub, you MUST install a new ABS sensor.

 

As far as the plastic collar--take a pick to it, and slowly lift it out of the hub. It will come out.

 

Now you also know which side was triggering false ABS signals---the side that broke.

 

I would also take your VIN to the local dealer--have them check for any open recalls. Some trucks are covered, under recall for this, some are not.

they both came out the same way, almost like they were supposed to come out like that..apparently not though...are they 100% garbage or can they still function, it seems they come out of that sleeve pretty damn easy

Iron,

Did the plastic come off with the sensors? When you first took them off?

you must measure the voltage at the sensor connector for more than 350MV AC...while rotating the hub.....you may need to use a fine file to remove the rust ...they must be mounted on clean metal ...only .001 of rust will give a low reading..if you get 500++MV AC you should not have any problems...

 

the sensors are junk ..this is a typical designed to fail part with GM charging excessive amounts for a 5.oo part made by slave labor...

 

 

it you have any metal on the sensor pick up the bearing/hub is n/g...

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
