My 2002 Altima Sometime the ABS kick in even though in a nice sunny dry road condition, sometime jerking when driving (doesn't matter high or low speed), sometime ABS. Tracking Control and Slip lights all on at the same time.
I did a lots of research over the internet, not much firm solution I can find. A lot of tech suggest the ABS sensor, MAF sensor, Spark plugs and/ or wires, Fuel injectors, Cad converter, etc. but no one know what is the exact problem is because it only happened intermittently.
But if I unplugged one of the ABS sensor, the ABS system will disable, the ABS. Tracking Control and Slip lights will all turn on, but the car have no more jerking and ABS kick in problem. So it will not be the MAF sensor, Spark plugs and/ or wires, Fuel injectors, Cad converter, etc.
To diagnostics and replaced a ABS sensor are very expensive, especially everyone said, when removed the sensor, 99% of the time the blot will break, it need a lots of time to get the remaining bolt back out, that is one of the reason which causing the repair cost so expensive, take up to $300 to 400 to change one sensor.
I am going to show you how to replace both sensor in a very cheap way.
Most of the forum I found and the majority possible problem cause are the rear ABS sensors. Not quite sure left or right, so I went to the Pick and Pull yard to bought a used pair of rear ABS sensors, it cost me CND$30.00, $15.00 each. Way cheaper than you take it out to just get diagnostic.
Follow the sensor wire and plug to replaced both sensors. My car run perfect now, no more jerking, no more ABS kick in by no reason, no more warning light turn on anymore.
Now comes to the biggest problem, when I removed the old sensor, I knew the bolt was going to broke. How can I re-tighten it back? No problem, just let it broke.
This is the way how I fix it: cut a piece of solid electrical wire, about 7 inch long, peel off the wire skin, I only need the copper wire (because copper wire is rust and heat proof).
Unscrew both bigger wheel bearing screws beside the sensor.
Bend the copper wire wrap around the screws, the middle of the wire need to put it through to hold down the back side of the sensor, when tighten the screws back, both screws will tighten the wire and hold down the sensor.
It is very hard to explain , I am going to attach some pictures to show everyone. Basically, with the tax I use around $32.00 to fix the problem.
Sorry about the last picture is quite fuzzy, it is hard to let my camera to get it focus properly, but you should be able to see it.
Because I already did mine, so I just use another screws to show everyone in the pictures how to do it. Also sorry for my English, hope every can understand what I mean.
Cut a wire around 7 inch long.
Peel off the wire skin, only need a solid copper wire
Bend it and wrap around the screw (in clockwise direction because it will be tighten in the same direction), cut the excessive length of wire if need
After bend will be in S shape.
Will mount it back to the car like that.
Finished, when tighten both screws, it will hold the sensor down tight.
