So I get an ABS light.
The error code determines it is the passenger side front sensor. The correct resistance is about 18K ohms. The bad sensor shows about 9 ohms. No problem, just replace it.
First, the cost is about $400.00. The same on EBAY.
This has to be the most expensive sensor on any car.
SIDEBAR – Oregon is a wet place. Every 12 months I change the brake fluid with new DOT 4. In the process of bleeding the brakes on the lift rack, a front after market, Teflon lined stainless steel braid covered hose blows up (In the middle)!! The hose is about 8 years old. Wow, I am very lucky. The only thing to do is change all five of the suspect hoses and I do. I don’t want to damn all fancy aftermarket hoses, but damn, this should not happen.
So I go to the local wrecking yard to get something off of the network. The good news is the sensor has been used for many years on the Troopers. Being me, I want to buy a full set. The cost is $150.00 for all four. How about two set for my friends in need. I ask, “These are working sensors, right?”. They say they come off a working car. A week passes and the parts arrive from Salem Oregon. I visit the wrecking yard and find two great balls of bubble wrap, each weighing about 50 lbs.. What’s up with that?
They sent 8 complete hubs with a sensor in each. I am not being charged for shipping, so who cares.
We unwrap the bubble wrap and find the sensors. We take off the retaining bolt and try to remove the steel flange from the hub. We pry, we tap, we wrench. It turns out the body of the sensor is plastic where it inserts into the hub. Brake heat has bonded the plastic to the hub. Penetrating oil will not penetrate. I leave the wrecking yard crew with the removal task. This is an awful design. It should have a metal sleeve for $400.00.
Two days pass and I visit. Good news, the sensors have been removed. All six of them. Two were broken in the removal. Which two? Yup, the front ones. I have two fronts left, They come as Right and Left. The cable brackets determines the side. I measure the resistance of all six sensors. Only one is bad. Yup, it’s the passenger side. I pry off and swap the two brackets from the Pass and Driver side sensors. Last but not least, the electrical connector is broken on only this one sensor.
Today I had the new-used Left-Right ABS sensor installed. The shop had to take off the hub to remove the old sensor. All back and the ABS light is off at last. No code reset was needed.
I have one spare Right and one Left REAR sensor, if anyone needs one. $40.00 plus shipping. I will keep them as stock.
Cheers, Roy
