Product Description
Core Product Description
The 89546-42030 Toyota Speed Sensor is an ABS wheel speed sensor for the rear left-hand side of select Toyota RAV4 models. Also known as a wheel speed sensor or ABS sensor, this component monitors the rotational speed of the rear left wheel and transmits this information to the ABS control unit. The system uses this data to prevent wheel lockup during braking and to maintain vehicle stability.
The sensor is a direct replacement component designed for the second-generation RAV4. It is mounted near the rear left wheel hub and uses a magnetic pickup to generate a speed signal. Over time, sensors can fail due to wiring damage, corrosion, or internal electronic failure, triggering the ABS warning light and potentially disabling the ABS system.
Product Attributes
When Should You Replace It?

FAQ
Q1: How can I be sure this speed sensor fits my RAV4?
A1: The most reliable method is to check the existing part number on your vehicle's rear left speed sensor. This part is confirmed for RAV4 (2001-2005). Always verify via VIN.
Q2: Is this the left or right side part?
A2: This is the rear left-hand side (LH) speed sensor. The corresponding right side part number is 89545-42030 .
Q3: What are the symptoms of a faulty speed sensor?
A3: Common symptoms include the ABS warning light staying on, traction control system issues, and possible fault codes such as C0205 or C0215.
Q4: Do I need to clear fault codes after installation?
A4: Yes. After replacing the sensor, a diagnostic scan tool may be required to clear stored ABS fault codes and turn off the warning light.

Related Product Recommendations
When replacing the ABS wheel speed sensor, it is often recommended to inspect and consider replacing the following related components at the same time. These parts share the same brake system and operating environment.
Recommended Related Parts:
Right-Hand Side Rear Speed Sensor – The corresponding rear right ABS sensor. Part number 89545-42030 . Replacing both rear sensors together ensures consistent performance.
Front Speed Sensors – If rear sensors are showing wear or failure, front sensors may also be approaching end of life. Inspect both front sensors.
Wheel Bearing / Hub Assembly – The speed sensor reads from the tone ring integrated into the wheel bearing. If the bearing is worn, it can affect sensor signal.
