Brake Antilock Wheel Speed Sensor problems of the 2007 Toyota Yaris

As I was driving this past winter the abs required maintenance and parking brake came illuminated at the same time. I thought it might have been a frozen connector since the winter has been very cold and bad this year. The speed sensor pig tail and the rear wheel bearing went out. This part was coroded and full of dirt and grime. Even the wires were disengrated. This has happened to other Yaris owners to that I have read on here. This should be a recall. Aproximate cost of fixing this problem is 600. 00.

Break and abs lights on and Toyota knew this was caused by speed sensor corrosion. Which disabled the abs system. Called the dealer but they asked me to call Toyota. I called Toyota, they said problems were not the defect and refused to provide any solutions, asked me to dealer for repair. The Toyota case number is 1302120332.

2007 Toyota Yaris -- abs and brake issue (defective speed sensors) this appears to be a common problem, and unfortunately, my vehicle is also affected. This is mentioned in Toyota service bulletin TSB-0120-08, but Toyota is unwilling to fix my defective speed sensors without charging ~$700.

The contact owns a 2007 Toyota Yaris. While driving approximately 5 mph, the abs and brake lights illuminated. The vehicle was taken to an independent mechanic where the technician stated that the driver side and passenger side speed sensors in the wheel bearings were corroded and would need to be replaced. The vehicle was repaired. The VIN was unavailable. The approximate failure mileage was 76,000. Updated 04/06/lj.

In December 2010, our '07 Yaris' abs light started to turn on intermittently. As days passed, it remained on longer and longer until it just stayed on all the time. Would have lived with no abs except for the fact that we had a newborn on the way. Also, the brake system sporadically shuttered and malfunctioned oddly under normal driving conditions. So we bit the bullet and got it fixed in may 2011. Turns out, the right rear speed sensor malfunctioned due to water infiltration. This is a well known issue and discussed in posts all over the internet. Our Yaris is a commuter car and has never been in water other than what lays on the highway while we drive in rain and snow. It is only a matter of time until the left side goes. We couldn't afford the $800 fix the first time around, but we managed. But we sure won't have the money for the next fix. It just isn't right. My argument is simple: a speed sensor is not an item that should wear out and malfunction in three years. What's more, Toyota has since redesigned this assembly-what I take as their admission of responsibility for the faulty design of this critical abs component. How many other Yaris owners are out there right now who can't afford this expensive fix. Their brake systems working improperly? they do so not just because of a failed part design by Toyota, but more so because Toyota willingly chooses to ignore this widespread problem, refusing to take the responsible action of initiating a recall of this vital safety component. Sadly, it will likely take serious injury or death and the subsequent lawsuit before someone at Toyota cares to take notice. I tried numerous times to speak with Toyota (local dealer and corporate), but they offered no recourse other than to file my complaint. I was told the same as so many others:"your warranty is expired. Sorry, we can't help you. " I am hopeful NHTSA will.

Thirteen months have passed and now I have a failure of the left rear wheel speed sensor to match the failed right rear wheel speed sensor that was replaced. The repair action will be to replace the sensor and wiring harness. Due to excessive corrosion, the dealer is recommending replacement of both the left and right rear wheel speed sensor wiring. This will be the third rear wheel speed sensor failure on two Yaris that I have had to deal with in 14 months. The cold weather and salt used on the roads during a snowy winter appear to wreak havoc on the connection between the wiring harness and the rear wheel speed sensors on the Yaris sedans. A little internet research will lead you to the conclusion that this is a very common problem in canada or anywhere where salt is used on the roads in winter. Since this problem does not present itself on the corolla in the same way, then there must be a design issue on the Yaris. A proper water/weather tight connection between the wiring harness and the rear wheel speed sensors would solve this issue. This is a safety issue as the intermittent connection causes erratic operation (if any) of the abs on these models. I believe there is a TSB released on this subject, but no recall. Consumers (me) are footing the bill for this defect. Three times and counting.

I own a 2007 Toyota Yaris, purchased August 2006. The brake and abs indicator lights starting coming on intermittently in December 2009 (often when it was raining or snowing outside), my dealer said that this was caused by an issue with the right rear speed sensor, and shouldn't indicate any actual problems with the brakes. However, soon afterward (January 2010), I started experiencing brake problems---the brake pedal would shudder or vibrate occasionally, even when I was driving on a smooth surface at low speeds. Even pumping the breaks, I had trouble stopping and slid through a stop sign more than once. My dealer said this indicated that the abs was kicking in when it shouldn't, and recommended a $600 replacement of the right rear speed sensor. I got this repair done, and the problem seems to be solved.

A bad connector leading to the abs speed sensor failed on our Toyota Yaris causing two warning lights to come on. Owners manual states to "stop immediately and contact Toyota dealer". Abs speed sensor was replaced at a cost of over $500 but in fact the problem is a corroded connector. Toyota and dealer stated that a technical serivce bulletin was issued regarding this problem. I was then told that because a "connector" not a "module" failed this problem in not subject to a recall. However, since manual says to "stop immediately" which freaked out my wife this clearly is a safety problem. Also, it should not take $500 to replace a faulty connector. I found a chat-room online where it became clear that many others are having this problem.

The abs light would start coming on from time to time. It would stay on for days at a time (during which time I had no abs), then go off for no reason. The brake pedal started to shudder and vibrate whether or not I was touching it. If it happened to be vibrating while I was actually braking, brake power would be heavily reduced. This has caused me to have to swerve out of the way several times so I don't rear-end someone. This has happened every winter since 2009, and has not gone off since last winter (2011/2012). Many other Yaris owners have complained of this same problem happening. Many attribute it to one or both of the rear wheel sensors. Some have had this replaced for many hundreds of dollars by Toyota; while it fixes the problem for a while, the new sensor becomes faulty within a couple of years (absurdly short amount of time). I believe this is due to water infiltrating the speed sensor. A recall should be made to replace the rear wheel sensors with ones that have better water protection. Toyota has since redesigned the rear wheel sensors on the new Yaris, but fails to offer a recall on the many thousands of dangerous Yaris' on the road.
