P1715 Lexus Code - Rear Wheel Speed Sensor Malfunction

Code P1715 indicates a Rear Wheel Speed Sensor Malfunction, meaning the vehicle’s system has detected an issue with the signal from one of the rear wheel speed sensors.

Common symptoms include ABS or traction control warning lights, erratic speedometer readings, and possible loss of ABS or traction control functionality.

Causes include a faulty rear wheel speed sensor, damaged or corroded wiring, a loose sensor connection, or issues with the ABS module.

While the car may still be drivable, safety systems like ABS and traction control may be disabled, increasing the risk of losing control in slippery conditions.

Start by using an OBDII scanner to confirm the code, inspect the rear wheel speed sensor and its wiring for damage, and check for loose or corroded connections.

The faulty sensor must be replaced. Ensure the replacement sensor is compatible with your Lexus model and clear the code with an OBDII scanner after installation.

You’ll typically need a jack and jack stands, a multimeter for testing, a socket set, and an OBDII scanner to diagnose and clear the code.

Yes, excessive dirt, debris, or rust on the wheel hub can interfere with the sensor’s ability to read wheel speed accurately. Cleaning the hub might resolve the issue.

Repair costs typically range from $100 to $300, depending on whether you replace the sensor yourself or have a mechanic perform the repair.

Regularly inspect the wheel speed sensors and wiring for damage, keep wheel hubs clean, and address ABS system warnings promptly to prevent recurring issues.
