Bought this vehicle three weeks ago. My ABS light is on, tire pressure gauge is on, (checked psi, tires holding consistent pressure) and my traction control light is on and will not turn off when clicking the button. I have tried to reset my battery and still nothing works. Does anybody have any idea on what I should do next? I have read a couple things that it may be a speed sensor or even just a wheel sensor. Thank you in advance.
Do you
have the same problem?

Welcome to 2CarPros.

First, it isn't uncommon for the tire pressure monitors to fail. They each have a separate battery that usually lasts about 5 years. However, make sure the pressure is at what is listed inside the driver's door on the tire information label. The only way to confirm that is with a TPMS scanner which can tell you if there is a signal from the sensor.

Next, I feel somewhat confident the ABS and Traction control lights which are both on have something to do with a bad wheel speed sensor. The ABS and TC are tied together. If one fails, the other will. With that in mind, I suggest testing the wheel speed sensors. Here is a link that shows how it is done. Other than this type of test, you will need a live data scanner that can read ABS codes:

Here is a short video showing how it is done:

That is the first thing I would check. Also, here are a few links you may find helpful:

______________________________

I know that seems like a lot of information, but I added it in case you need it. If you find one of the sensors is bad, here are the directions for replacing it. I will start with the front and then the rear. All attached pictures correlate with these directions.

Front:

REMOVAL
BRAKE CONTROL: FRONT SPEED SENSOR: REMOVAL

HINT
* Use the same procedure for the RH and LH sides.
* The procedures listed below are for the LH side.

1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

2. REMOVE FRONT WHEEL

3. REMOVE FRONT FENDER LINER LH

HINT
It is not necessary to fully remove the fender liner. Partially remove it so that the speed sensor connector can be disconnected in a later step.

4. REMOVE FRONT SPEED SENSOR LH

(a)Disconnect the sensor connector.

picture 1

(b)Remove the sensor clip (labeled A), bolt (labeled B) and sensor clamp (labeled C).

picture 2

(c)Remove the sensor clip (labeled D), bolt (labeled E) and sensor clamp (labeled F).

picture 3

(d)Remove the bolt and sensor body from the knuckle.

INSTALLATION
BRAKE CONTROL: FRONT SPEED SENSOR: INSTALLATION

HINT
* Use the same procedure for the RH and LH sides.
* The procedures listed below are for the LH side.

1. INSTALL SPEED SENSOR FRONT LH

NOTICE:
To prevent interference with other parts, do not twist the painted line areas of the sensor wire when installing it.

(a)Set the sensor body into the knuckle, and then install the sensor with the bolt.

NOTICE:
* Keep the sensor tip and sensor installation hole free from foreign matter.
* Firmly insert the sensor body into the knuckle before tightening the bolt.
* After installing the sensor to the knuckle, make sure that there is no clearance between the sensor stay and knuckle. Also make sure that no foreign matter is stuck between the parts.
* To prevent interference between the sensor and magnetic rotor, do not rotate the sensor body during or after the insertion of the sensor body to the knuckle.

(b)Install the sensor clamp and sensor clip as follows.

(1)Simultaneously perform the following: 1) hang the hook part of the sensor clamp (labeled A) on the flexible hose bracket (labeled C); and 2) insert the hook part of the sensor clamp (labeled B) into the flexible hose bracket (labeled D).

NOTICE:
Do not twist the sensor wire when installing the clamp.

(2)Install the sensor clamp to the flexible hose clamp and flexible hose bracket with the bolt (labeled E).

Torque : 19 Nm (189 kgf-cm, 14 ft-lbf)

(3)Insert the sensor clip (labeled F) into the hole on the absorber lower bracket.

(c)Install the sensor clamp and sensor clip as follows.

picture 7

(1)Set the sensor clamp (labeled G) on the side member, and then install the bolt (labeled H).

Torque : 8.5 Nm (87 kgf-cm, 75 in-lbf)

NOTICE:
Do not twist the sensor wire when installing the clamp.

(2)Insert the sensor clip (labeled I) into the hole on the apron.

(d)Connect the sensor connector.
