89542-52030 SENSOR, SPEED, FRONT RH For TOYOTA YARIS VIOS 8954252030

Product Function Description

The ABS wheel speed sensor is a critical component of your Toyota Yaris anti-lock braking system. This sensor monitors the rotational speed of the front right wheel and transmits this data to the ABS control module. The module uses this real-time information to detect wheel lock-up during braking and modulate brake pressure accordingly, preventing skidding and maintaining steering control . For Toyota Yaris (2006-2011) models, a properly functioning front right speed sensor is essential for safe braking performance, reliable traction control, and overall vehicle stability . This component is designed to factory specifications, ensuring proper fit and reliable signal output.

Common Symptoms of a Failing ABS Speed Sensor

If you are experiencing any of the following symptoms, your ABS speed sensor may be failing and in need of replacement:

• ABS warning light illuminated: The yellow ABS warning light stays on after the engine starts – this is the most common indicator of a faulty sensor

• Traction control light on: The TRAC or VSC warning light illuminates alongside the ABS light

• ABS activates unexpectedly: The ABS system engages during normal braking, causing pedal pulsing when it shouldn‘t

• Speedometer malfunction: The speedometer reads erratically or stops working (on some vehicles, the speed sensor also feeds the speedometer)

• Braking performance issues: The ABS system fails to activate when needed, or the vehicle takes longer to stop in emergency situations

• Diagnostic trouble codes: Codes related to the ABS wheel speed sensor circuit appear (C0035-C0050 range, depending on the specific fault)

If you have confirmed these symptoms through inspection, replacing the ABS speed sensor is the recommended solution.

• Address ABS warning lights promptly to maintain braking safety.

FAQ

Q1: How can I be sure this sensor fits my vehicle?
A1: Check the existing part number on your current sensor. This part fits Toyota Yaris (NCP9#, 2006-2011) front right position. Always verify via VIN.

Q2: Is this sensor for the left or right side?
A2: This sensor is for the front right (passenger side) . The front left uses part number 89543-52030.

Q3: What is the cable length of this sensor?
A3: The cable length is approximately 1120 mm.

Q4: What are the symptoms of a failing ABS sensor?
A4: Common symptoms include ABS warning light, traction control light, ABS activation at low speeds, and braking instability.

After Replacement Still Having Issues?

Replaced the ABS sensor but still having issues? Check these:

1. Was the tone ring inspected? – Damaged or dirty tone ring causes false signals

2. Is the sensor properly seated? – Incorrect positioning affects signal quality

3. Is the connector fully engaged? – Loose connection causes intermittent faults

4. Is the wiring damaged? – Check for cuts, chafing, or corrosion along the cable

5. Are fault codes cleared? – Old codes may persist until cleared with a scan tool

6. Is the ABS module functioning? – A faulty module can cause sensor-related symptoms

7. Is the correct sensor installed? – Front left and right sensors are not interchangeable
